Series PF2A digital flow switches provide a digital display monitoring air flow. The sensors are available both with a built-in display (rotatable) or remote panel-mountable display. Up to four sensors can be monitored by a single PF2_200 series 4-channel monitor, resulting in a 76% reduction in installation space. The sensors provide three types of outputs--NPN or PNP digital, voltage or current type analog, and cumulative pulse type outputs. The PF2A series flow switches are water resistant and conform to IP65. CE marked. Request catalog ES100-54A for more information.
