These spring loaded probe assemblies offer a choice of two styles of protection heads to meet environmental and size requirements. The probes can move up to 1/2 " in the direction of the head's axis. The thermocouples are available in J, K, T or E calibrations, with either 304SS or Inconel® sheathing (high temperature Super OMEGACLAD™XL or 321SS provided on request).
Standard lengths are 12" including 1/2" for the pipe thread in the relaxed state. Other probe lengths are available. Both the thread on the spring loaded probe and the extension wire opening are 1/2" NPT. The NB2 head includes a compression fitting nut and rubber ferrule for 1/8" to 1/4" O.D. wires or tubing.

The moving internal terminal block with attached probe is standard on all models. Consult the Custom Engineering Dept. for price and delivery on a wide variety of non-metallic and other specialized heads.

If ordering an NB1-CASS-14U-12-SL, is the actual probe length 11.5" (including 0.5" of NPT thread insertion)?

Asked by: harley1
That is correct the probe from tip to 0.5" up the NPT threads is 12".
