Wireless pressure sensor for pressure monitoring and alarm applications

13 September 2016

SignalFire Wireless Telemetry has introduced Pressure Scout, an intrinsically safe wireless pressure sensor that supports pressure monitoring and alarm reporting as part of the SignalFire Remote Sensing System.  

The first in a line of wireless integrated sensors, the Pressure Scout consists of a pressure sensor integrated with a wireless node and internal battery. The Pressure Scout is said to offer a low-cost alternative to conduit-wired or other wireless pressure monitoring solutions. Applications could include well tubing and casing pressure monitoring, tank level monitoring and compressor station status monitoring.  

As part of a wireless remote monitoring and control network, the Pressure Scout provides along-range transmission to the Signal Fire Gateway where pressure data becomes available via a Modbus RTU or TCP interface. Available in standard pressure ranges, it performs rapid (5 sec) pressure sampling with configurable alarm reporting. Units offer local pushbutton zeroing. Operable in temperature ranges from 40ºC to 80ºC the Pressure Scout can also operate in challenging outdoor environments.  

Operating on low power, the unit utilizes an internal battery that powers the integrated pressure sensor and radio for up to 10 years. For example, an application requiring a five second pressure sample interval for alarming, with a one minute reporting interval will last for 6.5 years. Extremely compact, units are both easy to install and maintain.
