This sensor measures differential pressure or air volume flow. The measured values are transmitted via the analogue output and via Modbus RTU. The output type is selectable: 0-10 VDC / 0-20 mA / 0-100 % PWM. The differential pressure range and all other settings can be adjusted via Modbus RTU. Some settings can be adjusted via jumpers. The supply voltage is 24 VAC or 24 VDC. It can be used in the range of 0 to 2.000 Pa.
