Industry-first wireless pressure gauge improves safety

Emerson Process Management has introduced the industry’s first wireless HART pressure gauge.

The Rosemount wireless pressure gauge (WPG) enables remote collection of field data, keeping operators updated on changing field conditions and improving personnel safety by reducing manual operator rounds and field exposure.

Mechanical gauges face quality and reliability issues commonly associated with overpressure, vibration, corrosion, extreme temperatures, and accidental damage.

Additionally, mechanical gauges are unable to communicate a device status.

Emerson’s new Rosemount WPG utilises field-proven piezoresistive sensor technology to deliver reliable pressure readings.

With the flexibility to accommodate changing process conditions, the WPG also gives up to 150 times greater overpressure protection compared to traditional gauges, which provides for a safer field environment by using two layers of process isolation.

Bourdon tube gauges have traditionally been a mainstay for taking pressure readings in the field, but are limited to visual indication of process conditions when an operator is present.

Bourdon tubes also use moving parts, which can break or wear over time due to use and vibration, leading to inaccurate readings or spillage.

The WPG eliminates mechanical gauges’ common weak points by removing the components that inhibit the device from reporting and displaying pressure and providing up to a 10-year life, which reduces maintenance cost and time.

The large 4.5” (11.5cm) gauge face provides easy field visibility.
