Resistance thermometers TOPE3, TOPE4 are designed for screw-fitting directly into process or into machine parts. Adjustable spring force of sensor provides optimum measurement conditions in environment where vibrations and turbulences appears. Additional external thermowell of TOPE3 version allows for easy sensor disassembly without unsealing process installation. These thermometers are suitable for liquid and gaseous media under moderate mechanical load and normal chemical conditions.
TOPE3 sensor consists of thermometric resistor, protection tube made out of stainless steel, connection cable, adjustable bayonet cap with spring and additional external thermowell with threaded process connection. TOPE4 sensor is provided with bayonet adaptor, without additional external thermowell.
Insertion length, process connection, construction type, number of sensors, accuracy, cable insulation and method of connection can be selected individually for the respective application.
