DPC200-AC, measuring range: 0...6000 Pa (Pascal) Output: 0...10 V (Volt), supply voltage: 90...260 VAC (alternating current) / (50 / 60 Hz)
The DPCs are electromechanical differential pressure/volume flow controllers with a diaphragm measuring system and comprehensive evaluation software. They are used to measure and control the smallest differential pressures of non-aggressive gases, especially air.
The DPCs are electromechanical controllers for differential pressure and volume flow that use a diaphragm measuring system and comprehensive evaluation software. They are ideal for measuring and controlling very low differential pressures of non-aggressive gases, especially air.
They are ideal for use in the field of air conditioning technology, e.g. for controlling fans, monitoring room pressure or regulating filters. The devices make it possible to control the air flow or maintain a constant pressure in a closed environment.
In addition to the analog output, there is a further alarm output (open collector, max. 30 V / 30 mA or relay 250 Vac / 10 A) for limit value monitoring or filter monitoring. The device provides a standardized output signal as a volume flow sensor. For pressure or volume flow control, the output signal is used as a manipulated variable for PI control.
