Contact Pressure Gauge Double NO 0..4bar (58psi) Stainless Steel 100mm Class 1 Below Connection

Contact pressure gauges are pressure gauges with an integrated pressure switch. Depending on the pointer position of the indicating measuring instrument, switch contacts make or break circuits. This contact pressure gauge has a connection point located below the gauge and measures pressure from 0 to 4bar (0 to 58psi). The scale division is 0.1 bar and the measurement accuracy class is 1 (±1% maximum deviation). The case is made of stainless steel and it has a G 1/2 inch stainless steel 306l (1.4404) connection port. It has an IP65 rating, and is suitable for a temperature range of -20 to 200 °C (-4 and 392 °F). This gauge has double normally open (NO) contacts. The 1st and 2nd contacts close when the respective setpoint value is exceeded. The recommended minimum difference between two contacts is 20% of the measuring span. The switch hysteresis is typically 2..5%. This version is a magnetic-snap action model with switch version S. Check the datasheet for the maximum switching power. Furthermore, for low voltages the load should never be below 20mA to guarantee good switching reliability.

A calibration certificate is not available.
