The EE471 temperature sensor with remote probe measures reliably
the temperature (T) in applications with space restrictions and is
optimized for building automation, HVAC and process control.
Analogue, Digital and Passive Outputs
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, EE471 features a wide choice of sensing
elements for passive T measurement.
Easy Installation
The design with remote probe is appropriate for installations where
electronic shall be protected against high temperature or strong vibrations. Product specific information for the remote probe is printed all along the cable. The innovative immersion well is
dedicated for measurement in liquids and allow for fast and safety replacement of the sensor.
Configurable and Adjustable
An optional adapter and the free EE-PCS Product Configuration Software facilitate the setup and adjustment of the
EE471.
