Easytemp TSM487
Compact thermometer with screw-in thread
for universal applications
Application
The TSM487 compact thermometer is used for universal
applications. Preferred applications are where
no high process pressures and no extreme temperatures appear.
Function
The compact thermometer assembly includes a fiberglass insulated
insert which is protected by a thermowell with process connection
. The terminal head is according to DIN 43729, form B, and is
G½”
made of aluminum. The built-in head transmitter converts the
resistance value into a temperature linear 4...20 mA analog output
signal.
