Belden Inc. 83930 0101000 Type J Thermocouple Cable

Product Description

The BELDEN INC. 83930 0101000 is a Type J thermocouple extension cable designed to carry low-level millivolt signals from a Type J thermocouple sensor back to a controller, indicator, or data acquisition system. Built in a 1-pair, 20 AWG configuration, this cable maintains signal integrity over the run length between the sensing point and the instrument. Type J thermocouples use an iron/constantan junction and are common in industrial process environments where temperature measurement accuracy is critical. Licensed electricians and instrumentation technicians typically install and terminate this cable during panel wiring, equipment commissioning, or sensor replacement work.

This extension cable is suited for industrial and commercial applications where Type J thermocouple signals must be extended without introducing measurement error. Proper use of matched-alloy thermocouple extension cable, rather than standard copper wire, prevents the introduction of parasitic thermoelectric voltages at junctions. Typical installation scenarios include connecting wall- or equipment-mounted Type J sensors to PLCs, temperature transmitters, or strip chart recorders in manufacturing, HVAC control panels, and process heating systems.

Key Features

• Type J thermocouple extension cable maintains iron/constantan signal compatibility
• 1-pair construction keeps the signal circuit self-contained within a single cable run
• 20 AWG conductor size provides a balance of flexibility and current-carrying capacity for instrumentation runs
• Designed to minimize thermoelectric error when used with matched Type J sensing elements

Compatibility

Designed as an extension cable for use with Type J thermocouple sensors in industrial and commercial instrumentation systems. Specific compatible equipment or model numbers were not provided in the product data.

Installation Notes

Installation should be performed by a licensed electrician or qualified instrumentation technician familiar with low-level signal wiring practices. De-energize all associated control circuits before terminating or replacing thermocouple extension cable. Maintain polarity throughout the run, as reversing conductors will produce inverted or erroneous temperature readings. Routing should avoid parallel runs with high-voltage power conductors to minimize induced noise on the millivolt signal.
