Description
Description
The F12IS Digital Gas Transmitter is an Intrinsically Safe (IS) version of ATI’s explosion proof D12 transmitter. In its standard form, it is designed for detection of a variety of toxic gases in hazardous area applications requiring IS devices. In addition, it is also well suited for all general purpose applications where toxic gas measurement is required. For IS installations, this transmitter is also available with a Hart communication option.
Series F12IS Digital Gas Transmitter use ATI’s standard smart sensors for maximum flexibility. Sensors are easily exchanged and contain all calibration constants in sensor memory, eliminating the need for field calibration of transmitters. Sensors may be calibrated on the bench and then simply plugged into the transmitter. Calibration data is read into the transmitter automatically and no other adjustments are normally required. For general purpose gas detection applications, the F12IS transmitter is also available in Non-IS versions. One version provides for easy interface to RS-485 networks using a standard MODBUS communication protocol. A second version provides a complete AC powered instrument with 3 alarm relays (SPST) available for external alarming.
