## Overview

The Murphy 20T-250-4-1/2 Temperature Swichgage combines precise temperature monitoring (130-250°F) with a built-in electrical switch to trigger alarms or shutdowns. Housed in a corrosion-resistant steel case with a break-resistant polycarbonate lens, it features a 4-foot sealed capillary tube and a self-cleaning contact mechanism for reliable, long-lasting performance in demanding industrial environments.

## Description

The 20T-250-4-1/2 is a 2" Temperature Swichgage. This very popular design features a diaphragm-actuated, temperature-indicating gage, with a built-in electrical switch for tripping alarms and/or shutdown devices. This model has a 4 foot capillary length with a standard 1/2-14 NPT threading, and a temperature range from 130-250°F (54-121°C). The gage mechanism is enclosed in a steel case coated to resist corrosion. A polycarbonate, break-resistant lens and a polished, stainless steel bezel help protect this rugged, built-to-last instrument. This vapor actuated gage features a sealed capillary tube and a sensing bulb. When subjected to heat, the liquid in the sensing bulb changes to vapor creating pressure against the diaphragm mechanism. The diaphragm translates this vapor pressure into a mechanical gage reading. Inside the 20T-250-4-1/2, the gage pointer acts as a temperature indicator and as one switch pole which completes a circuit when it touches the adjustable limit contact. Contact(s) are grounded through the Swichgage case. This gage has a self-cleaning motion to enhance electrical continuity.
