Modular sensor platform with interchangeable sensing probes

The Sigma 05 performs as a sensor hub for E+E Elektronik’s intelligent Modbus probes. It makes it simple to set up a modular sensor platform with up to three probes and five measurands. The device supports the company's sensing probes for CO2, humidity, temperature, ambient pressure and air velocity, making it ideal for a wide variety of applications.

The platform can manage up to three sensing probes centrally with an RS485 interface and the Modbus RTU protocol. Its compatible sensing probes are automatically identified by the sensor hub and are instantly ready for use. Of the five supported physical quantities, three may be assigned to the graphic display and two to the freely configurable analogue outputs.

The sensing probes are connected to the platform either directly or by an M12 cable. Connecting and replacing the intelligent probes is easy and quick, thanks to the plug-and-play functionality.

The platform features a rugged IP65/NEMA 4 enclosure and is offered with or without a display. With the multiple, high-quality sensing probes, it can be employed in HVAC, cleanroom or agricultural applications, for example. Thanks to its modular plug-and-play design, the sensor platform provides a high degree of flexibility.
