Threaded thermometer
Description
The model TFT35 threaded thermometer is used for temperature measurement of liquid and gaseous media in the range -50 ... +200 °C [-58 ... +392 °F].
It can be used for pressures up to 100 bar. All electrical components are protected against splash water and are designed to withstand vibration.
The thermowell with fixed threaded connection or adjustable compression fitting enables direct installation into the process. All wetted parts and also the case are from stainless steel.
The case and the exchangeable measuring insert are screwed together using a knurled nut. This enables the exchange of the measuring insert without having to remove the instrument from the process.
