The Gastronics’ True Wireless^� Transmitters feature a unique patented method of wireless monitoring that eliminates not only the high installation costs of hardwired systems, but the cost of wireless RTU’s.

The Gastronics’ True Wireless^� Transmitters incorporate up to a 5 watt UHF (450-470mHZ) radio directly into the gas transmitter, thus eliminating the need for wiring to a Remote Radio Terminal Unit (also known as an RTU). A typical radio telemetry system using RTU’s, while reducing significant installation costs, still requires both the high cost of the RTU as well as the installation costs to wire the gas monitor to the RTU. The True Wireless� Transmitters go a step further by completely eliminating the need for the RTU as well as the associated installation costs.

The Gastronics’ True Wireless^� Transmitters are designed to radio transmit PPM levels, battery voltage and alarm information directly to one or more Gastronics RTU’s. The keypad on the face of the True Wireless^� allows the user to configure site addresses, trigger on change levels, analog filtering, STEL/Hi/HiHi alarms and security access codes. A separate maintenance security access code allows an authorized maintenance person to access sensor calibration settings from the same keypad. The True Wireless� Transmitter radio strength is sufficient to penetrate in and out of buildings, throughout an industrial plant facility and miles beyond.
