DESCRIPTION

 

Murphy offers a variety of highly reliable thermocouple and RTD (Resistance Temperature Detector) assemblies and 4-20 mA DC output RTD transmitters.

 

 

 

Their innovative features include a 304 stainless steel thermowell that provides protection to the spring-loaded element. The cast aluminum connecting head meets NEMA 4 requirements and includes an RTD transmitter or a ther- mocouple/RTD terminal block mounted on ceramic Steatite and rated NEC Class 2.

 

The complete assemblies are offered in 2-1/2, 4-1/2, or 7-1/2 in. thermowell insertion lengths.

 

THERMOCOUPLE ASSEMBLIES WITH THERMOWELL

Available in types J or K, the thermocouple assemblies have ungrounded elements in a 304 stainless steel spring loaded sheath. For product compatibility see back page (replacement parts and thermocouple extension wire are available).

 

RTD ASSEMBLIES WITH THERMOWELL

Resistance temperature detector (RTD) assemblies are available with a 100 ohm platinum element, 3- wire leads, and spring loaded 316L stainless steel ele- ment sheath.

 

 

RTD TRANSMITTER ASSEMBLIES WITH THERMOWELL

 

RTDT assemblies transmit process variable temperatures. Available as part of the temperature sensor assemblies or as a separate units, the RTDT’s accept 2 or 3 wire, 100 ohm RTD’s. The RTD transmitters are loop powered, they feature linearized 4-20 mA DC outputs and have reversed polarity protection.

 

 

 

 

APPLICATIONS

 

Murphy’s temperature sensing assemblies fit in a variety of industrial processes and applications. Their ruggedness and characteristics make these assemblies a popular and price-competitive choice.
