From steel plants and power stations to refineries and defence facilities, industrial operations often depend on specialised equipment that consumers rarely see.
Temperature measurement and control is one such area.
The Tempsens IPO brings a long-established industrial technology company to the public markets. Based in Udaipur, Tempsens manufactures temperature sensors, industrial heaters and specialised cables designed to operate in demanding industrial environments.
Founded in 1976, the company remains family-run and is now managed across three generations. Its customers are primarily businesses and industrial organisations rather than individual consumers.
The company has reported healthy revenue and profit growth in FY26. However, cash generation declined because more money became tied up in inventory and working capital.
Another important point is the structure of the IPO: around 85% of the issue is an Offer for Sale, meaning most of the money raised will go to existing shareholders rather than the company.
This makes it important for investors to understand both the business fundamentals and what the IPO proceeds actually mean.

What Does Tempsens Do?
Tempsens manufactures specialised products used to measure, monitor and control temperature in industrial environments.
Its customers include businesses operating in sectors such as:
- Steel
- Power
- Refineries
- Defence
- Heavy manufacturing
- Other industrial applications
The company operates entirely in the B2B market.
Its products are not typically sold directly to consumers. Instead, they become part of industrial plants, machinery and production processes.
This gives Tempsens exposure to industrial capital expenditure and manufacturing activity.
What Products Does Tempsens Manufacture?
Tempsens operates across three main product categories.
Temperature Sensors
Temperature sensors are the company’s largest product segment, contributing approximately 45% of revenue.
These include devices such as:
- Thermocouples
- RTDs
- Infrared temperature measurement systems
Thermocouples and RTDs are sensors that measure temperature through direct contact.
The company also manufactures infrared systems that can measure temperature from a distance without physically touching the object.
This can be particularly useful in high-temperature or hazardous industrial environments.
Industrial Heaters
Industrial heaters contribute approximately 21% of revenue.
These products are used to heat materials during manufacturing and industrial processes.
Applications can include furnaces, production equipment and other industrial heating requirements.
Specialised Industrial Cables
Specialised cables contribute approximately 35% of revenue.
Unlike standard electrical cables used in homes and offices, these cables are designed to operate in harsh environments.
They can be engineered to withstand:
- Extreme temperatures
- Fire
- Corrosive conditions
- Heavy industrial environments
This gives the company exposure to industries where reliability and product durability are particularly important.
Why Is Tempsens’s Temperature Sensor Business Important?
Tempsens has a strong position in India’s temperature measurement market.
The company is India’s largest temperature-sensor manufacturer by revenue.
One notable differentiator is its infrared temperature measurement business.
According to the information provided, Tempsens is the only Indian company manufacturing these non-contact infrared temperature measurement products, while other Indian players rely on imports.
This creates a potential competitive advantage because domestic manufacturing can reduce dependence on imported equipment and may allow the company to respond more quickly to local customer requirements.
However, investors should continue evaluating whether this advantage translates into sustainable pricing power and long-term growth.
How Strong Are Tempsens’s FY26 Financials?
Tempsens reported healthy growth in both revenue and profitability during FY26.
Financial Snapshot
| Particulars | FY25 | FY26 |
| Revenue | ₹379 crore | ₹445 crore |
| Profit After Tax | ₹63 crore | ₹71 crore |
| Operating Cash Flow | ₹54 crore | ₹42 crore |
Revenue increased approximately 17.5% to ₹445 crore.
Profit after tax increased around 13.6% to ₹71 crore.
This shows that the company continued to grow despite operating in a specialised industrial segment.
However, operating cash flow moved in the opposite direction.
Why Did Cash Flow Decline Despite Higher Profit?
Operating cash flow declined from approximately ₹54 crore to ₹42 crore during FY26.
The primary reason was higher working capital.
Approximately ₹21 crore became tied up in additional inventory.
In simple terms, the company had more money invested in products and materials that had not yet been sold or converted into cash.
This creates an important difference between accounting profit and actual cash generation.
Why Does Inventory Matter?
Imagine Tempsens manufactures products worth ₹20 crore but does not immediately sell them.
The company may incur manufacturing and material costs today, while the revenue and cash collection occur later.
The business can therefore report healthy profitability while having less cash available at the same time.
For an industrial manufacturer, inventory is necessary to fulfil orders and maintain production.
However, continuously increasing inventory can put pressure on cash flow.
What Is the Working Capital Risk?
Another important indicator is the time taken for money to move through the company’s operating cycle.
According to the information provided, the period increased from approximately 152 days to 210 days over two years.
That represents an increase of around 38%.
A longer working-capital cycle means more money remains tied up between purchasing materials, manufacturing products, selling them and finally collecting payment.
This is worth monitoring because continued growth in the working-capital cycle could require additional financing.
If you are trying to understand whether working-capital pressure affects the overall investment case, a financial advisor in Ahmedabad can help assess the company’s cash conversion and financial position alongside your broader portfolio.
What Are the Main Risks in the Tempsens IPO?
Although Tempsens has a strong position in its niche, investors should consider several risks.
Working Capital Is Increasing
The biggest financial concern is the increasing amount of time the company takes to convert operating investments into cash.
The operating cycle increased from approximately 152 days to 210 days.

This contributed to the decline in operating cash flow despite higher profit.
Investors may therefore want to monitor:
- Inventory levels
- Receivables
- Operating cash flow
- Working capital requirements
Legal Dispute at an Acquired Company
Tempsens acquired Techin Gauges during FY26.
The acquired company is involved in a legal dispute involving approximately ₹11 crore.
According to the information provided, a partner company alleges that directors of Techin Gauges diverted business from a shared customer to a company operated by their own family.
The case remains pending.
This is an important governance and legal risk because the dispute relates to the operations of a newly acquired business.
Investors should monitor the eventual outcome and whether the matter results in any financial or operational impact.
How Is the Tempsens IPO Structured?
The total IPO issue size is approximately ₹650 crore.
However, most of the issue is not fresh capital.
Issue Structure
| Component | Amount |
| Offer for Sale | ₹555 crore |
| Fresh Issue | ₹95 crore |
| Total Issue | ₹650 crore |
Approximately 85% of the IPO is an Offer for Sale.
This means existing shareholders are selling a substantial portion of their holdings.
Only ₹95 crore will be raised as fresh capital for the company.
How Will the Fresh Issue Be Used?
The company plans to use the ₹95 crore fresh issue proceeds for:
| Purpose | Approximate Amount |
| Debt Repayment | ₹55 crore |
| Equipment & Capacity | ₹18 crore |
| General Corporate Purposes | Balance |
The largest portion of fresh funds will be used to repay existing debt.
Around ₹18 crore will be allocated towards equipment and capacity-related requirements.
This means the company will receive relatively limited fresh capital compared with the overall IPO size.
Is the Tempsens IPO Mainly a Fundraise or an Exit?
This is an important question for investors.
With approximately ₹555 crore out of ₹650 crore coming through an Offer for Sale, the majority of the IPO proceeds will go to existing shareholders selling their shares.
Only ₹95 crore represents fresh capital for Tempsens.
Therefore, the IPO is primarily a partial exit for existing shareholders, rather than a large fundraise for business expansion.
An Offer for Sale does not automatically indicate a negative outlook.
However, investors should understand that the company’s balance sheet will not receive the full ₹650 crore.

How Should Investors Evaluate the Tempsens IPO?
Tempsens operates in a specialised industrial segment with established products and a strong position in temperature measurement.
The company has demonstrated:
- More than four decades of operating history.
- Leadership in India’s temperature-sensor market.
- Exposure to industrial sectors.
- Growing revenue.
- Growing profitability.
- A specialised non-contact temperature measurement offering.
- A diversified product portfolio.
However, investors should also evaluate:
- Increasing working capital requirements.
- Declining operating cash flow.
- Inventory build-up.
- The Techin Gauges legal dispute.
- The large Offer for Sale component.
- Future industrial demand.
- IPO valuation.
Imagine Amit, a long-term investor interested in India’s manufacturing sector.
He likes Tempsens because its products are specialised and serve industries such as steel, power and defence.
But instead of looking only at its market position, he also examines why cash flow declined despite profit growth and why the operating cycle has increased significantly.
He also considers how much of the IPO actually goes into the company.
This gives him a more complete picture of the investment opportunity.
Understanding Manufacturing IPOs With Professional Guidance
Specialised manufacturing companies require investors to examine more than revenue and profit growth.
Working capital, inventory management, customer payment cycles, debt, capacity utilisation and the purpose of the IPO proceeds can all affect the investment case.
A financial advisory company in India can help investors evaluate such businesses in the context of their investment goals, risk tolerance and existing portfolio allocation.
Professional guidance can be particularly useful when an IPO combines strong business fundamentals with issues such as declining cash conversion or a large Offer for Sale.
Conclusion
The Tempsens IPO offers investors exposure to a specialised industrial manufacturing company with a long operating history and a strong position in India’s temperature-sensor market.
The company has grown its revenue from ₹379 crore to ₹445 crore and profit from ₹63 crore to ₹71 crore in FY26.
However, cash generation has weakened.
Operating cash flow declined from ₹54 crore to ₹42 crore as more capital became tied up in inventory, while the operating cycle increased from approximately 152 days to 210 days.
The legal dispute involving the recently acquired Techin Gauges is another factor investors should monitor.
The IPO structure is also important. Approximately 85% of the ₹650 crore issue is an Offer for Sale, while only ₹95 crore represents fresh capital for the company.
Therefore, investors should not view the entire ₹650 crore as money being raised for business expansion.
As with any IPO, investors should evaluate business quality, cash flow, working capital, risks, valuation and their own investment objectives before making a decision.
