The EE071 accurately measures relative humidity and temperature and calculates physical quantitites such as dew point temperature, mixing ratio and absolute humidity.

The Modbus RTU digital interface allows for easy integration into networks. The compact design with M12 connector facilitates the installation and fast replacement of the probe.

The sensing element is perfectly protected against pollution and corrosion and stands for long term stability even in harsh environment. With an appropriate radiation shield EE071 is also suitable for outdoor applications.

  • What is the difference between Modbus RTU and Modbus TCP/IP?

    The main difference is the hardware interface. The Modbus RTU protocol runs on RS485 Hardware while Modbus TCP/IP protocol on Ethernet hardware.

  • What is the difference between a 2 wire and a 3 wire current output?

    Transmitter with "two-wires" technology receive the power from the process, and the signal is carry on return wire (closed current loop). With technology "three-wires" the power supply is separate from current output: 2 wires are the power supply and third carry the signal.
