Tempsens Instruments (India) Ltd – Company Overview

Incorporated in 1990, Tempsens Instruments (India) Limited is a diversified thermal engineering and specialised cable manufacturer engaged in the design and manufacture of customised temperature sensing solutions, electrical heating solutions, and specialised cables. The company caters to mission-critical applications across industries such as power generation, steel, oil & gas, petrochemicals, aerospace, pharmaceuticals, automotive, cement, nuclear, defence, and food processing.

Tempsens is the largest manufacturer of contact and non-contact temperature sensors in India by revenue, with an estimated 10.5% market share in the temperature sensor segment in Fiscal 2026. The company has also expanded its electrical heating business, strengthening its presence beyond its core temperature-sensing portfolio.

Between April 1, 2023 and March 31, 2026, Tempsens served more than 1,000 unique customers. Its customer base remains well diversified, with revenue from its top 10 customers consistently accounting for less than 19% during the period. The company follows a balanced Project/OEM and Maintenance, Repair and Operations (MRO) business model. While Project and OEM orders provide access to large, approval-intensive projects, MRO revenues are supported by recurring replacement requirements, regulatory compliance, and plant maintenance.

The company has a strong international presence, exporting its products to more than 80 countries, including the UAE, Germany and Poland. Its global operations are supported by 15 manufacturing units and 28 distributors, with a presence across Asia Pacific, Africa and the Middle East, Europe, and North and South America. As of March 31, 2026, Tempsens had 731 permanent employees.
