Wireless Monitors suit hazardous locations.

Press Release Summary:

Explosion-proof ac and dc Wireless Systems offer continuous monitoring and transmission of 4-20 mA, temperature, and pressure signals out of Division 1 area to safe area, eliminating need for conduit and cable runs in hazardous locations. NEMA 4X version is available for non-explosion-proof applications where waterproof protection is required. Units offer range up to 3,000 ft with no line of sight. Transmit power is 1 mW to 1 W and data transmit interval is 1-60 sec.

Adalet Wireless Offers Continuous Wireless Monitoring In Hazardous Locations

Cleveland, OH, December 1, 2004 - Two new explosionproof wireless systems have been added to the Adalet Wireless family of products. Joining the recently introduced battery powered wireless system are an AC and a DC powered system which are designed for continuous monitoring and transmission of 4 to 20mA, temperature, and pressure signals out of a Division 1 area to a safe area, eliminating the need for costly conduit and cable runs in hazardous locations. A NEMA 4X version is also available for non-explosionproof applications where ruggedized, waterproof protection is required.

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 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.

The Adalet Wireless system come complete with either an Adalet explosionproof Division 1 or NEMA 4X enclosure, signal conditioning for thermocouple, RTD, or pressure transducer inputs, radio transmitter and antenna. A receiver unit is also included which can be installed in any of Adalet's cast aluminum, fiberglass, or stainless steel enclosures.
