SmartDisk
brings wireless communications to Pressure Relief Devices
Introduction
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. |
