Description

The 20P Series (2 inch/51mm dial) SWICHGAGE models are diaphragm-actuated, pressure-indicating gauges with built in electrical switches. These switches are used for tripping alarms and/or shutdown devices.

The 20P Series gauge mechanism is enclosed in a steel case coated to resist corrosion with a polycarbonate, break-resistant lens and a polished stainless steel bezel.

Accuracy and protection from moderate overpressure is assured by a unique, unitized diaphragm chamber. A built-in pulsation dampener helps eliminate pointer flutter and is removable for cleaning.

For the 20P Series the gauge pointer acts as a pressure indicator and as one switch pole which completes a circuit when it touches the adjustable limit contact.

These gauges have two adjustable contact points which trigger upon high/low pressure.
