Z-Gard

MSA’s Z-Gard DS Sensor is designed to detect the presence of carbon monoxide and nitrogen dioxide gases in vehicle storage areas, garages or anywhere else the toxic gases may be found. The electrochemical sensors generate a representative output signal proportional to the calibrated operating range. The sensors are available with two output options a 4-20mA analog output or an addressable RS-485 digital signal. Z-Gard Sensors with RS-485 digital output are specifically designed to operate as a system with any Z-Gard CXII or C 485 Controller. Z-Gard Sensors with 4-20mA can be installed as stand-alone sensors typically integrated with the Z-Gard C Controller or common commercial equipment including PLC, DCS or building automation systems. The sensor status is shown by the green OK LED, indicating proper device operation. The switch drive output can be changed to percentages of full-scale, which can be very useful for testing remote devices that may be connected to the sensor output.
