Gas Actuated Series Industrial Temperature Gauges are precision instruments designed to provide accurate temperature measurements using a gas-filled sensing element. These gauges operate by expanding and contracting a gas within a sealed chamber in response to temperature changes, which drives a pointer to indicate the temperature on a clear, easy-to-read dial. Ideal for high-pressure and high-temperature environments, they offer robust performance and durability. The gas-actuated design ensures reliable and stable readings, making these gauges essential for monitoring and controlling temperature in demanding industrial applications.
Suitable for media such as air, water, oil, gas, and chemicals that will not attack stainless steel parts. Typical applications will be in a general industrial heating, air- conditioning, food, petroleum, and chemical industry. Vibration resistant.
