      PRESSISION Temperature Sensor

      PRESSISION Temperature Sensor

      PRESSISION Temperature Sensor

      The ASHCROFT® PRESSISION temperature sensor measures the pressure of an inert gas contained in a gas cartridge to determine the temperature.

      All PRESSISION temperature sensors are tailored to the specifi c needs of the customer.

      Size, shape and material of the temperature sensor, as well as the length of the connection of the stainless steel capillaries are always customer-specific.

      The main advantages of the PRESSISION temperature sensor are:

      • Best possible accuracy for temperature measurement <= 0.1 % of the measuring span
      • Safety – No electricity in the process
      • Measurement of the averaged temperature (along a length, over a diameter)
      • Short response time: Up to 5x faster than a mineral-insulated sensor
      • Alternative measuring principle to traditional measuring methods like Pt100 and thermocouples

      Performance Features

      • Averaged temperature over the temperature sensor
      • Customised temperature sensors up to several metres
      • Alternative to RTD’s and thermocouples
      • High stability, very low drift
      • Constant volume gas thermometer with high-precision pressure transmitter
      • Inert gas fi lling, pressure transmission via stainless steel capillary
      • Compensation of ambient temperature
