Description
Thermometer for use in nuclear power plants comprise:
- ■ Resistance thermometer, model TRN - ■ Thermowell/protection tube - ■ Accessories
The model TRN resistance thermometer can be combined with a large number of thermowell/protection tube designs. Operation without thermowell/protection tube is only recommended in certain applications.
Cable couplings are available as accessories.
Special features
- Measuring range from -50 ... +600 °C [-58 ... +1,112 °F]
- For mounting in all standard thermowell/protection tube designs
- Spring-loaded measuring insert
- Pt100 measuring resistors
