DPF-MITH-SI Temperature and Humidity Sensor MODBUS RTU RS-485
- Manufacturer: DPF Sensors
- Category: Meteorology – Climatology, SENSORS, Humidity Sensors, Temperature sensors, Temperature sensors for air conditioning, Temperature - Humidity
The DPF-MITH-SI from DPF Sensors It is a temperature and relative humidity sensor with communication MODBUS RTU RS-485, designed for industrial automation, HVAC, electrical panels and integration into BMS, PLC and SCADA systems.
The equipment allows continuous environmental monitoring in electrical cabinets, photovoltaic inverters, data centers, technical buildings and energy facilities, monitoring the internal conditions of sensitive electronic equipment.
Thanks to its highly stable capacitive technology, native MODBUS RTU output and support for IEEE-754 registers, the sensor is suitable for integration into industrial automation systems and remote monitoring.
The device incorporates digital temperature and humidity calibration using internal MODBUS registers.
The compact ABS UL94-V0 housing allows for wall or DIN rail mounting in industrial and energy applications.
