YNXC-100 Seismic-Resistant Magnetic Assist Electrical Contact Pressure Gauge

The YNXC-100 Electrical Contact Pressure Gauge combines accurate pressure indication with automatic electrical switching, making it an ideal solution for industrial pressure monitoring and process control.

Designed with a magnetic assist contact mechanism, the YNXC-100 provides reliable switching performance, excellent vibration resistance, and long service life in demanding industrial environments.

It is widely used in hydraulic systems, compressors, pumps, water treatment, petrochemical processing, and factory automation.

What Is an Electrical Contact Pressure Gauge?

An electrical contact pressure gauge measures pressure while simultaneously controlling electrical circuits through preset switching points.

When the pressure reaches the configured upper or lower limit, the internal electrical contacts automatically open or close, allowing the gauge to control equipment such as:

• Pumps

• Compressors

• Solenoid Valves

• PLC Systems

• Alarm Devices

• Industrial Controllers

Unlike a standard pressure gauge, it provides both visual pressure indication and automatic process control.

Working Principle

The YNXC-100 uses a precision Bourdon tube pressure sensing mechanism combined with a magnetic assist electrical contact system.

As pressure changes, the Bourdon tube drives the pointer across the dial.

When the pointer reaches a preset switching point, the magnetic-assisted contact mechanism activates, producing a stable switching signal with reduced arcing and improved contact reliability.

The magnetic assist design significantly extends contact life compared with conventional mechanical contact gauges.
