Cooper Bussmann 6142-20-3 Capillary Thermometer 48 in

Product Description

The COOPER BUSSMANN 6142-20-3 is a front-flange capillary thermometer designed to sense and help regulate temperature in refrigeration and HVAC equipment. With a 48-inch capillary length and a measurement range of -40 to 60 degrees F (-40 to 15 degrees C), this thermometer provides reliable temperature sensing across low-temperature applications. The front-flange mounting orientation simplifies panel installation and provides a secure, clean fit. HVAC technicians and refrigeration service pros use this type of instrument to monitor system temperatures and prevent equipment from operating outside safe thermal limits.

This thermometer is suited for use in refrigeration units, walk-in coolers, reach-in cases, and similar low-temperature enclosures where accurate capillary-based temperature sensing is required. The 48-inch capillary length allows for flexible probe placement relative to the control or display location. The operating range covers both standard refrigeration and sub-zero applications, making it a practical fit for commercial and light industrial refrigeration service work.

Key Features

• 48-inch capillary length for flexible probe-to-controller routing
• Temperature range of -40 to 60 degrees F (-40 to 15 degrees C) covers typical refrigeration service needs
• Front-flange mounting orientation for panel or enclosure installation
• Compact housing: 6.75 inches long, 4.6 inches wide, 2.5 inches tall
• Lightweight at 0.33 pounds for easy handling and installation

Compatibility

Designed as an OEM-style replacement capillary thermometer for refrigeration and low-temperature HVAC equipment requiring a front-flange, 48-inch capillary sensing element in the -40 to 60 degrees F range.

Installation Notes

Installation should be performed by a qualified refrigeration technician or HVAC service professional. Power down and de-energize the unit before removing or installing any temperature sensing components. Ensure the capillary tube is routed without sharp kinks or contact with abrasive surfaces to maintain sensing accuracy. Follow applicable local codes and manufacturer service procedures when accessing sealed refrigeration systems.
