Product & DescriptionProduct Image
Standard Connector
Thermocouple Accessory

Provides quick coupling and is made to the standard industrial size, thus allowing mating with other regular size plugs and jacks. Made of rugged, thermosettling plastic which has a high impact strength. Extremely tough and shatterproof, these connectors exhibit a low moisture absorption rate, good dielectric constant, and are impervious to fungus attack. Finger grips allow easy handling. The bodies are color-coded to ISA color codes. Symbols for + and - are molded onto the connector body to simplify wiring.

Miniature Connectors
Thermocouple Accessory

Useful with fine thermocouple wire and small diameter probes. Accepts wires from .001" diameter to 20 gauge. Polarized pins make it impossible to mismate. Case is molded from glass-filled thermoset plastics (useful to 400°F). Simple two-piece construction includes removable cap with semi-captive screws and elastomer bushing for wire strain relief.

Compression Fittings
Thermocouple Accessory

Adjustable adapter used for installing thermocouples, RTDs, or other sensors with metal tubular sheaths in pipes or tanks. When the cap is tightened on the body, the ferrule is squeezed tightly and permanently around the probe's metal sheath. The compression fitting and probe assembly are then threaded into place at the temperature measuring site. This provides a torque-free, leak-proof seal.

Thermocouple Wire
Thermocouple Accessory

Standard Grade
Standard Grade meets or exceeds ISA specifications for accuracy. Both legs of the thermocouple wire pair are included in the footage quoted. A variety of insulation is offered to meet the requirements of diverse applications. If the wire is to be used to run more than 20 or 30 feet, it is usually preferable to use the larger, more heavily insulated extension grade wire for the distance run. Temperature limits are located below.


Extension Grade
Extension Grade is used mostly for connecting probes or "hot junctions" to instrumentation. It is generally larger wire and more heavily insulated than the standard grade in order to retard electrical losses along its length. The extension wire types JX and KX (corresponding to thermocouple types J and K) meet the same specifications for accuracy as standard grade up to a temperature of 400°F.
