E+E EE471 Specifications

EE471
Temperature Sensor with Remote Probe
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.
