The VSAN PT100 Temperature Sensor is a highly accurate platinum resistance temperature sensor designed for precise temperature measurement in industrial process applications. The PT100 is one of the most widely used temperature sensors across industries due to its exceptional accuracy, excellent repeatability, long-term stability, and reliable performance under demanding operating conditions.
The term PT100 refers to a platinum sensing element that has a resistance of 100 Ohms at 0°C, as defined by the international standard IEC 60751. As the process temperature changes, the resistance of the platinum element changes proportionally, allowing accurate and highly repeatable temperature measurement over a wide operating range.
The VSAN PT100 is manufactured using premium-quality platinum sensing elements enclosed within a rugged SS304, SS316, or SS316L stainless steel sheath, providing excellent resistance to corrosion, pressure, vibration, and harsh industrial environments. It is available in Simplex and Duplex configurations with 2-wire, 3-wire, and 4-wire connection options to meet different application requirements.
The sensor can be supplied with terminal head assemblies, mineral insulated (MI) cables, thermowells, threaded connections, flanged connections, compression fittings, sanitary fittings, and custom mounting arrangements, ensuring compatibility with a wide range of industrial installations.
The VSAN PT100 is suitable for measuring temperatures in liquids, gases, steam, and solid surfaces. It is fully compatible with Temperature Transmitters, Digital Temperature Indicators, PLC, DCS, SCADA Systems, Process Controllers, and Data Acquisition Systems, enabling seamless integration into modern industrial automation systems.
Manufactured according to IEC 60751 standards, the PT100 offers high measurement accuracy with Class A, Class B, and Class AA sensing elements. Its excellent stability, low drift, and long operational life minimize calibration requirements while ensuring dependable temperature monitoring.
The VSAN PT100 is widely used in Power Plants, Oil & Gas, Chemical Industries, Pharmaceutical Manufacturing, Food & Beverage Processing, Water Treatment Plants, Steel Plants, Cement Industries, HVAC Systems, Marine Applications, Paper & Pulp Mills, OEM Equipment, and Industrial Automation, where precise temperature measurement is essential for process control, safety, and operational efficiency.
With its rugged construction, superior measurement accuracy, excellent repeatability, and long service life, the VSAN PT100 provides a dependable solution for continuous industrial temperature monitoring.
The VSAN PT100 operates on the Resistance Temperature Measurement Principle.
The sensing element consists of high-purity platinum with a resistance of 100 Ohms at 0°C. As the process temperature increases, the electrical resistance of the platinum element increases in a predictable and nearly linear manner. Likewise, when the temperature decreases, the resistance decreases proportionally.
The change in resistance is measured by a temperature transmitter, digital indicator, or controller, which converts the resistance value into an accurate temperature reading using the standardized PT100 resistance-temperature relationship defined by IEC 60751.
For high-accuracy industrial applications, 3-wire and 4-wire configurations compensate for lead wire resistance, significantly reducing measurement errors over long cable distances.
The excellent linearity and stability of platinum enable the PT100 sensor to provide highly accurate and repeatable temperature measurements throughout its service life.
The VSAN PT100 Temperature Sensor is extensively used for accurate temperature measurement and process monitoring across a wide range of industries.
