integrity. Not an electronic test of some kind but a true test of sensor response to gas.

MODEL F12/D TOXIC GAS DETECTOR INSTALLATION OPTIONS • Power: Available in 12-24 VDC, 115 VAC, or 230 VAC configurations The sensor holder in the F12/D is normally mounted to the transmitter enclosure. For applications where this configuration is not ideal, there are a number of different configurations for meeting specific requirements. These include a 6 ft. (1.9 m) cable extension, a remote junction box for longer sensor separation distances, and a duct mount sensor. • Interchangeable Sensors: The F12/D accommodates 60 different sensor modules • Sensor Verification: Auto-Test generator option...

SMART SENSORS The F12/D uses ATI smart sensors that allow easy interchangeability. Each sensor contains signal conditioning electronics and data memory. Sensors can be calibrated using a spare unit in the shop to avoid using calibration gases in the plant. Sensors may also be returned to ATI for factory calibration, which is useful for gases that are costly or difficult to obtain. Each sensor adjustment (zero or span) is stored in sensor memory and can be reviewed on the F12/D display. This data is very useful in assessing the sensor's condition and estimating remaining sensor life. AVAILABLE...
