Vapour Expansion Series Temperature Industrial Gauges are precise instruments designed to measure temperature in various industrial applications using a vapour-filled sensing element. These gauges operate by detecting the expansion and contraction of a vapor within a sealed chamber, which drives a pointer to indicate the temperature on a clear, easy-to-read dial. Ideal for environments with high pressure or fluctuating temperatures, the vapour expansion design ensures accurate and stable readings. Built for durability and reliability, these gauges are essential for maintaining optimal process conditions and ensuring operational efficiency in industrial settings.
Suitable for media such as air, water, oil, gas, and chemicals that will not attack brass parts. Typical applications will be in demanding automotive, portable air compressors / generators and earth moving equipment where distance reading is required. Vibration resistant.
