THE INTRISTICALLY SAFE MONITORING SYSTEM WITH INTELLIGENT SENSORS

摘要

The paper presents the extended intrinsically safe systems of temperature monitoring which use heavy duty temperature cables with intelligent sensors. Intelligent sensors are connected in unique 1-Wire interface. Similarly, other sensors detecting humidity, flow on base 1-Wire interface, may be controlled in this system. These systems are applicable to grain elevators and cooperation objects in the same storage, for example: silos batteries, horizontal storages and others. In these large-area objects there are many independent computer stations cooperating with the central station. Application tests have confirmed advantages of the intelligent sensors and their usefulness in temperature monitoring systems and particularly: accuracy, reliability, facility for intrinsically safe systems, low cost etc.
