Indoor Temperature Humidity Sensor

We are engaged in manufacturing, exporting and supplying excellent quality Indoor Temperature Humidity Sensor in Padova, Veneto, Italy.
HD48. and HD49. series of transmitters measure temperature, relative humidity and dew point. Versions with only standard analog output or with only RS485 output with MODBUSRTU protocol are available. The models with analog output provide a signal suitable for transmission to a remote display, recorder or PLC. The models with RS485 output are suitable for connection to a PC or PLC.
The models of the HD48. series are active transmitters and accept both direct and 24Vac alternating power supply; they have standard current (4a 20mA) or voltage (0a 10V) outputs, or a serial RS485 output, depending on the model. The models of the HD49. series are passive transmitters instead, and thus suitable to be inserted in a 4a 20mA current loop.
The HD48. and HD49. series of transmitters are designed for temperature and humidity
The HD48.. and HD49.. transmitters measure relative humidity with a well proven temperature compensated capacitive sensor that assures precise and reliable measurements in the course of time. The transmitters of the HD48.. and HD49.. series are available in two probe temperature ranges:
standard -20a +80A C and extended -40a +150A C for the most critical applications. A stainless steel 20I m filter protects the sensors against dust and particles (other filters are available for different applications).
