E+E EE431 Specifications

EE431
The EE431 duct and immersion sensor measures reliably the temperature (T) in air and liquids and is optimized for building automation, HVAC and process control.
Duct and Immersion Temperature Sensor
Analogue, Digital and Passive Outputs
EE431 + mounting flange
The T 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. In addition, EE431 features a wide choice of sensing elements for passive T measurement.
Easy Installation
The device can be mounted either with the plastic mounting
EE431 + immersion well
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.
Configurable and Adjustable
An optional adapter and the free EE-PCS Product Configuration Software facilitate the setup and adjustment of the EE431.
