UM344-2

MODEL DESIGNATION AND SPECIFICATIONS

Table 8.4 provides a list of replacement thermocouples and RTDs for Model 344T series thermal sensors. In critcal applications, it may be desirable to have on-hand spare elements. All thermal elements are 1/4” in diameter with a 316SS sheath and grounded measuring junction. All thermal elements are spring loaded. The length of the assembly, computed as A + F + U, must be supplied. For cast aluminum or cast iron connection heads add 2” to the computed length for T/Cs and RTDs.

Table 8.5 lists thermocouple wire for common thermocouple types. Thermocouple wire is twisted-shielded pair, 20 gauge, PVC insulated. RTD wire is 16 or 20 gauge 3-wire twisted-shielded.
