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.
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.
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.
Available Sensing Probes for Sigma 05
EE072 - Humidity and Temperature Probe
EE074 - Temperature Probe
EE671 - HVAC Air Velocity Probe
EE680 - Air Velocity and Temperature Sensor for Laminar Flow

A functional and accuracy check of the Sigma 05 can be performed with the E+E Reference Probe Modbus RTU instead of the regular sensing probes. The reference probe supplies fixed values for a wide choice of measurands and features an individual certificate. Refer to the Reference Probe Modbus RTU Quick Guide for further details.
