2.2 Description
The model TR57-M pipe surface resistance thermometer consists of a
temperature probe and a clamping xture (pipe adapter).
Any change in the temperature causes a change in the resistance of the
sensor in the temperature probe. This change can be measured directly
or can, optionally, be converted via a temperature transmitter into a
4 ... 20 mA signal proportional to the temperature.
The clamping xture serves to adapt the temperature probe to the
process and features a detachable connection which enables the
dismounting of the temperature probe. The entire measuring chain
(sensor, transmitter if required, connection cable) can be calibrated on
site, without having to disconnect the electrical connections.
