Modular Sensor platform
EE680
The Sigma 05 sensor hub represents the central element of the E+E modular sensor ecosystem with intelligent probes, analogue outputs and display. With pluggable, interchangeable probes, the modular sensor platform is suitable even for harsh and challenging environment. The Sigma 05 is available with polycarbonate or die-cast aluminium enclosure. 30 is a state-of-the-art hand-held for precise measurement of various physical quantities, such as humidity, temperature, dew point, CO₂, air velocity, volumetric flow and air pressure.

Sigma 05 with EE072 and EE872 probes
Sigma 05 without display
Flexibility: Multiple Probes and Measurands
The Sigma 05 accommodates up to 3 E+E sensing probes with RS485 interface and Modbus RTU protocol. Up to 5 measurands can be assigned to the two freely selectable and scaleable analogue outputs and to the optional graphic display.
Plug-and-Play
Sigma 05 features automatic detection of E+E probes and performs an autonomous, rule based hub setup. Refer to the user manual for details.
Configuration and Adjustment
The free PCS10 Product Configuration Software allows for easy setup of the Sigma 05, measurand assignment and thresholds, display layout, scaling of the analogue outputs and adjustment of the connected probes.
