E+E ELEKTRONIK EE431 – DUCT AND IMMERSION TEMPERATURE SENSOR

The EE431 duct and immersion sensor reliably measures the temperature (T) in air and liquids and is optimized for building automation, HVAC and process control. It is engineered for long-term stability and ease of integration. For liquid applications, the stainless steel probe is used with a thermowell, utilizing a unique fixing spring that ensures constant thermal contact between the sensor and the well. For air applications, it mounts directly to the duct wall. The device is highly flexible, allowing users to configure measuring ranges and communication parameters via internal DIP switches or an optional USB configuration adapter.

The measured data is available on the voltage or current output, as well as on the RS485 interface with Modbus RTU. 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.
