Easytemp TSM187

Compact thermometer with screw-in thread
for challenging applications

Application

The TSM187 compact thermometer range covers a wide variety of
market needs worldwide. Typical application can be found in the
chemical and pharmaceutical industry, food, water and waste water
and power plants. Preferred applications are
where requirements are short response time mechanical strength.

Function

The compact thermometer assembly includes a replaceable insert in
mineral insulated cable which is protected by a thermowell with
process connection . The terminal head is according to DIN
43729, form B, and is thermally uncoupled by a extension neck.
The built-in head transmitter converts the resistance value into a
temperature linear 4...20 mA analog output signal.
