Relative humidity and temperature probe DB4385

duct-mountresistanceRS-485

RS485 Interface Duct Humidity and Temperature Sensor for HVAC DB4385 sensor is designed to measure the temperature and relative humidity of interior air in spaces by a common internal sensor, whose signal is processed by a microprocessor and converted into a MODBUS RTU output signal. It is widely used in measurement scenarios such as industrial sites, telecommunication base stations, offices, supermarkets, production workshops, warehouses, and construction sites. Specification Measurement range - Humidity:0%RH~100%RH; Temperature:-40~120℃(measurement range supports customization) Accuracy@20%RH~80%RH @25℃ - Humidity:±3%RH; Temperature:±0.4℃ Interface - RS485, Modbus RTU Response time - 1.6s Programmable address - 1~255 Baud rate - 1200~115200 Supply voltage - 12~24VDC Transmitter operating temperature - -20℃~80℃ Power consumption - ＜4W Material - Transmitter:cast aluminum; Probe:304 stainless steel; Probe:copper sintering
