Applications: Adjustable Over Pressure Protectors are used to protect pressure gauges and sensors against the effects of pressures exceeding their maximum rating. They allow low pressures to be measured with great accuracy by a gauge whose rating is less than the maximum pressure that could occur in the process and without damaging the gauge by too high a pressure. Each protector is adjusted to the maximum permissible pressure that the gauge to which it is fitted will withstand and will automatically shut off the gauge if this is exceeded. The valve will remain closed until the system pressure drops approx. 30% below the closing pressure, where upon the force of the spring will open the valve.
