Spring-Loaded RTD/Thermowell Assemblies
with General-Purpose Connection Heads
Spring-Loaded RTD/Thermowell Assemblies with General-Purpose Connection Heads are designed for use with various thermowell types.
Complete assemblies can be ordered by selecting the RTD assembly below, the thermowell from the thermowell section of this catalog, and a
temperature transmitter from the back of this section. Assemblies without a thermowell can be ordered by selecting the sensor assembly from
this page and inserting the "S" length in table 2-0. These sensors are supplied with a 316 stainless steel sheath and are available in various
tolerances and temperature ranges as noted in the tables below.
