Senva TGD-ACX-A : Duct Mount Toxic Gas CO Sensor/Controller, 0-10V, 0-5V, 1-5V and 4-20mA Selectable Output, LCD Display, Clear/Tinted Enclosure, 7-Year Warranty
The Senva TGD-ACX-A is a duct-mounted toxic gas carbon monoxide (CO) sensor and controller with various selectable 0-10V, 0-5V, 1-5V, and 4-20mA output. The TGD-ACX-A features a clear/tinted enclosure with an LCD display and comes with a 7-year warranty. It includes fan and alarm relays, each with specific setpoints that are menu-selectable. The 3-1/2 digit LCD display indicates CO levels, with corresponding LEDs for normal, warning/fan relay, and alarm/alarm relay conditions. An audible alarm with a 85dB Piezo transducer can be set to activate for 30 minutes above the alarm setpoint. The CO sensor, based on electrochemical technology, boasts an accuracy of ±5% of the default range and a resolution of 1ppm. The device is UL2034 Listed Component certified.
Applications
- Ensure adequate air flow in occupied spaces
- Ideal fo parking lot garages
- Alert occupants of elevated gas levels
- Directly control exhaust fans
