Senva TGM-ANX-A : Metal Wall Mount Toxic Gas NO2 Sensor/Controller, 0-10V, 0-5V, 1-5V and 4-20mA Selectable Output, LCD Display, 7-Year Warranty
The Senva TGM-ANX-A is aMetal Wall Mount Toxic Gas NO2 Sensor/Controller, equipped with a range of selectable outputs including 0-10V, 0-5V, 1-5V, and 4-20mA, complemented by an LCD display and a remarkable 7-year warranty. This sensor/controller is designed for diverse applications, ensuring optimal air circulation in occupied spaces, making it ideal for parking lot garages. It serves to alert occupants of elevated gas levels and allows for direct control of exhaust fans. The specifications include a power supply of 15-30VDC/24VAC, with analog outputs and programmable options for versatile usage. The fan relay and alarm relay characteristics, along with their respective setpoints, provide comprehensive control. The 3-1/2 digit LCD displays NO2 ppm, while LEDs indicate the status with green for normal, yellow for warning/fan relay, and red for alarm/alarm relay. An audible alarm exposure feature, backed by an 85dB Piezo transducer, ensures heightened awareness in case of gas exposure exceeding setpoints. The NO2 sensor, based on electrochemical technology, boasts an accuracy of ±5% of the default range and a resolution of 0.1ppm, with a remarkable life expectancy exceeding 7 years.
