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

-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
