STT-27 High Pressure Temperature Sensor

High pressure temperature sensor.

The STT-27 High Pressure Temperature Sensor is designed for applications where the sensor is screwed directly into high pressure chambers or pipework. The housing is manufactured from 316 stainless steel and machined from a single piece of bar stock, helping eliminate welds and weak points in the design.

The sensing element can be supplied as a thermocouple, thermistor, or resistance thermometer, and is secured in place with solid epoxy potting. A range of cable options is available to suit the application and installation environment.

Key features

  • Pressure resistance up to 1000 bar

  • Thread options: BSP / NPT

  • Customisable probe diameter and immersion length

  • Available with thermocouple, thermistor, or resistance thermometer sensing elements

  • Suitable for media temperatures up to 250°C

  • Robust 316 stainless steel wetted parts

  • IP65 environmental protection
