Wireless Level Field Unit
The new Wireless Level Field Unit is designed to measure hydrostatic level in a vented tank and is available with an integrated sensor or an extended sensor. In situations where the level measurement point is low to the ground or the tank is surrounded by a containment dike, the extended sensor allows for more advantageous positioning of the wireless transceiver without compromising accuracy. This Field Unit is self-contained, fully wireless, and samples pressure at regular intervals based upon user specification. With a transmission range of up to 10,000 ft using extended range antennas, and a battery life of up to 5 years, these easily installed, FM approved, Class 1, Division 1 Level Field Unit provide measurement and monitoring variables that are often unattainable with wired solutions. The 900 MHz ISM license-free units assure complete security, with frequency-hopping spread spectrum (FHSS) communications technology.

Wireless Output Devices Allow Remote Monitoring
Complementing a line of integrated wireless field units, these analog, digital and analog/digital output modules enable processors to remotely monitor equipment and process conditions with no field wiring. They allow the integration of wireless monitoring instrumentation into existing control systems for a variety of applications. The analog modules provide four 4–20-mA analog outputs, the digital modules provide eight switch-closure outputs that report the conditions of the input switches and the status of the field units, and the analog/digital modules combine the capabilities of both. Typical installed costs are said to be 90% less than those of conventional wired devices.
