Pressure on wireless!

Emerson Process Management has introduced the industry’s first WirelessHART® pressure gauge. 

The Rosemount Wireless Pressure Gauge 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 are plagued with quality and reliability issues. These issues are commonly associated with overpressure, vibration, corrosion, extreme temperatures, and accidental damage. Additionally, mechanical gauges are unable to communicate a device status.

“As part of our Pervasive Sensing™ portfolio, this new gauge design fundamentally changes how customers use pressure gauges by helping them make better business decisions,” said Bob Karschnia, vice president and general manager of wireless products at Emerson Process Management. “Real-time insights provide actionable information that improves personnel safety while reducing facilities’ costs and time.”

Emerson’s new Rosemount Wireless Pressure Gauge utilises field-proven piezoresistive sensor technology to deliver reliable pressure readings. With the flexibility to accommodate changing process conditions, the Wireless Pressure Gauge also gives up to 150X 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, causing inaccurate readings or process to spill.

The Wireless Pressure Gauge eliminates mechanical gauge common weak points by removing the components that inhibit the device from reporting/displaying pressure and providing up to a 10-year life, which reduces maintenance cost and time. The large 4.5 inch (11.5cm) gauge face provides easy field visibility.
