Questions about our products?

The EE431 measures accurately the temperature of air or liquids in building automation, HVAC and process control.

The measured data is available on the voltage or current output, as well as on the RS485 interface with Modbus RTU or BACnet MS/TP protocol. Alternatively, the EE431 features a passive output with a wide choice of temperature sensing elements.

The device can be mounted either with the plastic mounting flange or via external mounting holes at the enclosure. The innovative immersion well is dedicated for measurement in liquids and allows for fast and safe replacement of the sensor. The EE431 with RS485 interface is appropriate for daisy-chain wiring.

An optional adapter and the free EE-PCS Product Configuration Software facilitate the setup and adjustment of the EE431.

FAQ

  • 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.
