Description

The resistance thermometer SCR120-Exi consists of an exchangeable measuring insert, a spacer with a mounting stub and an aluminum connection head in which it is possible to install a programmable temperature transmitter with a 4-20 mA output signal. The measuring insert is a replaceable element of the complete sensor, which significantly reduces the time and costs of servicing the measuring equipment on site. The spring-loaded mounting of the measuring insert ensures its perfect pressure to the bottom of the protective pipe installed on the facility, which shortens the response time to temperature changes and increases measurement accuracy and reduces natural vibrations, which translates into avoiding mechanical and electrical damage. The immersion length, process connection thread, spacer length and sensor head can be selected depending on the application needs/requirements.

Application areas:

  • installations of technological processes in all industries,
  • mechanical engineering,
  • heating, air conditioning and ventilation installations.
