Siemens Building Technology QFA2001 2-Wire Room Humidity Sensor 5% 4-20MA

Siemens QFA2001 Room Humidity Sensor is a highly advanced sensing device that does an efficient measure of indoor humidity. This sensor is designed for use in a number of HVAC systems with a sleek white polycarbonate housing to provide optimum indoor air quality. It measures range of 0 to 95 percent and has a 5% accuracy for a reliable performance. It operates on a 24 VAC voltage, and on a 2 wire configuration with a 4-20mA analog output, making it attractive for integration into existing control systems. The ability to provide precise humidity data for HVAC equipment allows it to perform the control of dehumidification and ventilation processes more precisely.
