ZGard S Sensor

The ZGard S Sensor is designed to detect the presence of carbon monoxide, nitrogen dioxide and combustible gases in air. These sensors employ solid state, electrochemical or catalytic sensors which generate a representative output signal proportional to the calibrated operating range. All Z Gard S Sensors are available with 2 output versions, 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.
