SmartDisk brings wireless communications to Pressure Relief Devices

The SmartDisk™ Wireless Sensor & Monitoring System provides intelligent, reliable and cost effective communications technology to pressure relief devices without the traditional expense of wiring between the pressure event sensor and the monitor.

Operating Principle

An ultra high frequency radio transmitter is fitted to a pressure event sensor. When an overpressure, flow or other pressure event occurs, the sensor changes state typically from “closed circuit” to “open circuit” and the transmitter broadcasts the event. A receiving station is configured to recognize this transmission.

The receiving station identifies a unique signal from the transmitter and issues an immediate alert identifying the pressure relief device and the pressure event. Annunciation of the event can be through a monitor integral to the receiving station, relay outputs in the receiving station, or existing user control systems. Any simple “change of state” sensor can be integrated into the SmartDisk Wireless Sensor & Monitor System, including: Burst Alert® Sensors, Leak Detector Alert Sensors, Proximity Switches, Pressure Switches, etc.
