Senva TGD-ACM-A : Duct Mount Dual Combustible Gas Sensor/Controller, Carbon Monoxide (CO) and Methane (CH4), 0-10V, 0-5V, 1-5V and 4-20mA Selectable Output, LCD Display, 7-Year Warranty
The Senva TGD-ACM-A is a duct mount dual combustible gas sensor/controller designed for monitoring Carbon Monoxide (CO) and Methane (CH4). It features selectable output options including 0-10V, 0-5V, 1-5V, and 4-20mA. Equipped with a 3-1/2 digit LCD display, this device comes with a 7-year warranty. The analog outputs are menu-selectable, and the fan relay, set at 300 ppm by default, is capable of handling 1A@24/30VDC. The alarm relay, set at 600 ppm by default, also has a 1A@24/30VDC capacity. The device includes LEDs indicating normal, relay, and alarm statuses, along with an audible alarm (85dB Piezo transducer) with a duration of 30 minutes above the alarm setpoint. The CO sensor, of electrochemical type, boasts an accuracy of ±5% of the default range and a life expectancy of over 7 years, covering an area of 5000-7500 square feet.
