E+E Sigma 05 is a modular sensor platform with interchangeable measuring sensors for the parameters: Relative humidity, Temperature, CO2 and Air velocity.

The Sigma 05 is a “Sensor Hub” for the intelligent E+E Modbus measuring sensors.
A modular sensor platform can be easily set up with three measuring probes for five different measured values.
The Sigma 05 supports E+E sensor probes for CO2, Relative Humidity, Temperature, Barometric Pressure and Air Velocity making the interface suitable for a wide variety of applications.

The measuring sensors are “plug and play” and are automatically recognized by the Sigma platform.
Up to three different RS485 (Modbus RTU) measuring sensors can be connected to the platform, of which 3 measured values can be shown on the display and two can be linked to a BMS or PLC system via freely programmable analog outputs.

The new free PSC10 configuration software makes it easy to configure the Sigma platform, set and scale measured values and calibrate connected measuring sensors.
For loop validation of the Sigma 05 system, reference measuring probes are available with fixed programmed measured values.

The interchangeability of the sensors and the universal properties of the Sigma 05 system make the platform suitable for a wide range of applications from Pharmaceuticals and Cleanrooms to HVAC and Agricultural applications.
