The 20T and 25T Mechanical Temperature Gauges are durable and precise instruments designed for reliable temperature measurement in various industrial applications. Featuring a mechanical design, these gauges operate without the need for external power, using a direct sensing mechanism to provide accurate temperature readings. The 20T and 25T models are known for their robust construction and clear, easy-to-read displays, making them suitable for monitoring temperatures in machinery, processing systems, and other demanding environments. Their dependable performance ensures effective temperature management and contributes to the safe and efficient operation of industrial systems.
The 20 Series (2 inch/51 mm dial) and the 25 Series (2-1/2 inch/64 mm dial) Swichgage models are diaphragm-actuated, temperature-indicating gages with built-in electrical switches for tripping alarms and/or shut-down devices.
Ranges are available from 32°-120°F (0°-45°C) through 300°-440°F (160°-220°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.
These vapor-actuated gages feature 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.
For series 20T and 25T, 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. They have a self-cleaning motion to enhance electrical continuity.
These instruments are used on equipment in oil field and monitoring engine coolant, crankcase oil and transmission oil.
