Conventional invasive type sensors such as RTDs and thermocouples with Thermowells were used to measure process media temperature inside a pipe. Surface temperature sensors were also used to approximate the inside temperature. However, the accuracy of surface temperature sensor is very poor due to ambient temperature fluctuation and other factors.
The major problem with these conventional types of sensors are as follows: -
- High installation time
- Leakage issues due to drilling
- Contamination of process media
- Poor accuracy
At Tempsens, we have developed India’s first noninvasive sensors for measuring the temperature of process media flowing inside the pipe. This sensor eliminate all of the major problems faced by conventional thermowell sensing technology and surface temperature sensors.
The clamp sensor is equipped with an Inbuilt four-digit LCD and microcontrollers ICS which offers many signal processing features. The electronic box with an integrated Keypad helps in setting parameters like pipe material (Mild steel, Stainless steel, copper, and many more ), pipe diameter, pipe schedule, Analog Output, Unit of temp(°C or °F), Response Time, and many more. Our standard non invasive clamp sensor come with 4- 20mA analog output. Other analog outputs options available are 0-20mA, 0-10V. RS-232/RS-485 serial interface card is available as optional.
The clamp sensor is provided with USB 2.0 output port which facilitate the user to take reading when and where required in PC/Computer or update software.The electronics can be powered through a USB port. In this case, no external power supply is required. 24 V DC is required for operation of Analog Output, RS - 232 & RS - 485 & Relay Output.
