These sensor assemblies are generally supplied to suit thermo pockets or thermowells but are also supplied as replacements or to suit existing thermo pockets & thermowells. It consists of a temperature sensing element housed in a stainless steel protective sheath and are spring loaded to ensure bottoming. They can be terminated with termination block, 4/20mA temperature transmitter or with flying leads to connect to existing unit. Available with PT100,PT1000,Thermocouple or NTC Thermistor.
