Pipe surface temperature sensor
  • Operating range -40...+80 °C or -30...+105 °C
  • Pt1000 sensor
  • For pipes Ø16...60 mm
  • PVC insulated cable

ET243 surface temperature sensor is designed for measuring temperature on closed pipe systems or other round or flat surfaces. The sensor can be conveniently fixed with a nylon cable tie without any mechanical preparation of the measurement site.

Indirect temperature measurement avoids disturbing flow of the medium and the measurement object is hardly affected by the low thermal mass of the sensor. On the other hand, lack of pressure and chemical effects ensures longer lifespan of the sensor.

It must be considered that large differences in temperature between the measurement medium and surroundings have a direct effect on the measurement result. In such cases, additional insulation around the sensor and the cable in at least 10 cm range is advisable. To improve heat transfer from surface to the sensor, heat-conductive paste can be supplied.
