Dial thermometers, Bi-metal

 

Dial thermometers with scale ranges from -200 to +700 °C

Dial thermometers work on the bimetal, expansion or gas actuation principle. This enables scale ranges of -200 to +700 °C in different class accuracies, response times and resilience to environmental influences. Diverse connection designs, stem diameters and individual stem lengths enable a flexible measuring location design. Dial thermometers with remote capillaries are particularly versatile. All thermometers are suited for operation in a thermowell if necessary.

Thermocouples

 

Thermocouples are temperature sensors that generate a voltage directly dependent on temperature. Compared to resistance thermometers, they are particularly suited for high temperatures up to 1,700 °C. Instrument designs from mineral-insulated sheathed cable are very resistant against extremely high vibration loads (depending on instrument model, sensor element and wetted materials). The accuracy classes 1 and 2 apply for thermocouples in accordance with IEC 60584 as well as the standard and special classes in accordance with ASTM E230.

 

A.   Thermocouple, Model TC10-0

Industrial assembly

 

Thermocouples in this series can be combined with a large number of thermowell designs. Use without a thermowell is permitted when using a fixed (welded) fitting.

Temperature transmitters

 

Temperature transmitters convert the input signal from a wide range of sensors, such as resistance sensors and thermocouples, but in some cases also from potentiometers, into a standardised output signal (e.g. 0 … 10 V or 4 … 20 mA). With digital temperature transmitters, the sensor type and the measuring span can be freely configured, along with many further options such as the error signalisation or a measuring location identification.
