## Description

The 20P-100 Pressure Swichgage is a 2" dial, diaphragm-actuated pressure-indicating gage with a built-in electrical limit switch, which is used for tripping alarms and/or shutdown devices. This dual-scale instrument has a range of 0-100 psi (690 kPa) [7.0 bar]. The gage mechanism is enclosed in a steel case coated to resist corrosion. A polycarbonate, break-resistant lens and a polished, stainless steel bezel help protect this rugged instrument. 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. Inside the 20P-100, the gage pointer acts as a pressure indicator and as one switch pole which completes a circuit when it touches the adjustable limit contact. Contacts are grounded through the case and have a self-cleaning motion to ensure electrical continuity. The 20P-100 Pressure Swichgage was specifically designed to protect engines and equipment in oil field, marine, irrigation, construction and trucking applications by monitoring engine lube pressure, water pump pressure, hydraulic pressure and air pressure. This popular instrument features a beryllium copper diaphragm, a 1/8-27 NPTM brass process connection, and exceeds SAE standards.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Good guage
*by P***R on September 26, 2019*

I put them on all my guzzis, well made. I have the hoses made at a local pneumatic hose shop and use a motorcycle alarm speaker instead of a warning light because i don't want to always be looking down at the dash.
