Hengesbach TP 30 Contact Resistance Thermometer

Hengesbach TP 30 Contact Resistance Thermometer temperature sensors have been specially designed to record the surface temperatures of resting media, e.g. tanks. The pressure with which the movable sensor tip is pressed against the surface (which may be uneven) optimize adaptation to the measuring point and guarantees recording of the surface temperatures during stationary processes, in combination with the head-sensitive, installed Pt100 measuring element.

The system is easy to install via the G½ welding socket, which – depending on the prevailing installation options – can be selected for installation either on top of or flush with the wall of the tank. Thermal conductance paste is recommended to improve heat transmission.

The resistance thermometers can be delivered either with a directly connected cable or with a stainless steel field housing and can also be used outdoors, as they fall into the protective category IP 67. Single or double PT100 temperature sensors according to EN 60751, Class A, guarantee a high degree of accuracy. Optional programmable measuring transducers can be used for longer transmission routes.

Hengesbach TP 30 Features:

  • no contact with the medium
  • head-sensitive installation of the measuring resistance for optimal temperature recordings
  • the measuring point can be retrofitted
  • optionally with cable connection or head transmitter
  • can be serviced during operation
