Pressure sensors from American Sensor Technologies (AST) are serving as components in a remote monitoring system that ensures optimal operations of safety trailers used on remote sites as emergency first aid stations.
Mining, construction, oil fields, and other industrial sites are often located miles away from medical facilities. Nomadic safety trailers are equipped with a variety of first aid equipment to immediately address medical conditions and stabilize an injured person until the arrival of first responders. To help monitor the readiness of their remote safety trailers, Nomadic uses a monitoring system from Global Monitoring to check the various operating parameters of each trailer.
Tracking Essential Operating Parameters
Integrated with AST pressure sensors and other transducers installed on the safety trailers, Global Monitoring's Messenger™ Remote Monitor tracks essential operating parameters of the Nomadic safety trailers on a 24/7 basis including: including water temperature and levels, fuel levels, ac power, and generator status.
Series AST44LP low pressure transducers monitor water levels of tanks installed in the trailers that supply an emergency shower and eyewash station. As water is dispensed from the emergency shower at a rate of 20 gal per minute and from the eyewash at a rate of 3 to 4 gal, Nomadic constantly monitors water level in the 315 gal tank to be sure there is always water available for use. Processing data provided by these Class I, Division I intrinsically safe pressure transmitters, the Messenger™ Remote Monitor provides periodic status reports to Nomadic Safety on water usage to indicate if trailers must be serviced before regular maintenance. The Messenger™ also sends alerts if AST pressure sensors indicate that water levels are below pre-programmed points.
The Messenger™ Remote Monitor automatically sends updates and service requests to key personnel via satellite as many remote sites do not have adequate cellular service or none at all. The Messenger™ uses low-Earth-orbit (LEO) communication satellites that orbit just a few hundred miles above the arth's surface to provide cost-effective tracking, monitoring, and messaging capabilities to and from anywhere in the world.
