The Sigma 05 can centrally manage up to three sensing probes with an RS485 interface and the Modbus RTU protocol. Compatible sensing probes are automatically identified by the sensor hub and immediately ready for use. Of the total of five supported physical quantities, three can be assigned to the graphic display and two to the freely configurable analog outputs. The sensor platform supports the company’s sensing probes for CO2, humidity, temperature, ambient pressure and air velocity.
