Thermocouple Spring-LoadedProbes with Connection Head

Spring-Loaded Probe

Open head

THMJ & K - CXX-03

THMJ & K - CXXR-03Replacement Probe

1/2” x 1/2” NPT HexNipple

Overview• All temperature sensors are pre-built stock items• Probe

- Spring-loaded for positive tip contact in thermowells- Type J or K thermocouple elements to meet many

temperature sensing applications- 1/4” diameter, 316 SS sheath to protect against harsh

environments- Magnesium Oxide (MgO) insulation provides

vibration dampening and protection against thermal shock

- 4”, 6” or 12” probe length• Connection Head

- Cast aluminum NEMA 4 screw cover head with captive gasket

- One turn cover removal & installation eliminatescross threading and saves time

- 3/4 NPT conduit opening with internal stop to prevent overtightening and installation damage

- Gripping ribs on cover edge- Stainless steel cover chain

• Wiring- Ceramic terminal base- Brass terminals with stainless steel screws eliminate

the need to wrap connections around screws- Elevated terminal block for easy wire termination

• Made in the USA

Overview• All thermowells are pre-built stock items• Thermowells designed for use with ProSense

spring-loaded thermocouple and RTD probeselminate the need for a separate probemounting fitting or adapter

• Drilled bar stock one piece construction (nowelds) from 304 or 316 stainless steel

• 1/2” and 3/4” NPT male process threads available

• Designs and fabrication comply with ASMEB31.1 and boiler and pressure vessel codes

• Material complies with NACE MR 0175 / ISO 15156

• CRN registered for all Canadian provinces• Made in the USA

-Using spring-loaded probe design ensures positive tip contact with thebottom of the thermowell.

-Probes with hex nipple thread directly into thermowell. No additionalprobe mounting fittings are required.

NOTE: RESPONSE TIME IS REDUCED WHEN INSTALLED IN A THERMOWELL. BE SURE TO INSTALL THE PROBE SO THAT IT CONTACTS THE END

OF THE THERMOWELL FOR FASTER RESPONSE.. THERMAL COMPOUND MAY BE USED DEPENDING ON APPLICATION
