These high pressure thermocouple plug sensors are ideal for vessel applications, pressurized containers and applications requiring mounted NPT security. The 304SS sheath has a 6.4mm (1/4") dia. that extends 1/2" from the end of the 1/4 or 1/8NPT pipe plug. Other length sheaths are available. The thermocouple-grade lead wires are stranded 20 AWG, fiberglass insulated, and stainless steel overbraided with stripped leads. Connectors are attached on request. Junctions are grounded or ungrounded for a pressure rating of up to 2500 psi. Exposed junctions are available for air or gas temperature measurements at ambient pressures. To tighten mounting threads, there is a hex section that is 22mm (.56") across flats that are 5.8mm (.23") wide.

Is the cable (excluding the leads) IP68 rated (i.e. can the cable be submersed underwater)?

Asked by: Max23
Thank you for your inquiry. No, the cable is not IP68 rated.

Hi - do these thermocouples couple with a certain reader/display/temperature logger? I would ideally want a logger/digital out reading and a digital temp display. Thank you!

Asked by: Jaja
Thank you for your inquiry. Yes. Please take a look at our thermocouple meter/datalogger models HH806AU and OM-HL-EH-TC. FYI these dataloggers will require a miniature male thermocouple connector. For more questions, please call 1-888-826-6342.
