Industrial Wireless System For OEM Sensors and Instruments

Cleveland, OH, - Adalet Wireless has announced an industrial wireless system specifically designed for manufacturers of sensors and monitoring instrumentation. The AWJA wireless system from Adalet Wireless provides a wireless link to any sensor or instrument which utilizes a contact closure or analog 4-20mA signal. The system has been designed for installations requiring point to point or multiple field transmission points. The Adalet Wireless multi-point system allows up to sixty field transmitters to communicate with one to four receiver base radios. The lightweight systems can be customized to include a company logo or unique color scheme for a complete OEM wireless system. A second version, the AWJD, is available for simple contact closures.

Adalet Wireless systems are an innovative, cost cutting solution for transmitting temperature, pressure, or other data signals in explosionproof Division 1 or industrial areas. Hazardous location wiring is extremely expensive or totally unfeasible in many applications. Adalet Wireless products eliminate the need for expensive conduit and wires in hazardous or any industrial location.

This major innovation by Adalet Wireless will enable many new, creative applications in Class I, Division 1 and industrial locations. Activities such as data collecting, sensor monitoring, and process control, previously unthinkable because of constraints with hard wiring, are now possible with the Adalet Wireless link. The process control engineer can now implement solutions never before available.
