PFMB, Digital Air Flow Sensor, 2-Color Display, IP40, 2-200 Lpm
PFMB7201 is a digital flow sensor compatible with air and nitrogen. Its thermal sensor is protected in a bypass flow path to reduce contact with moisture and contaminants, avoiding accuracy deterioration and damage. Dimensions and weight have been reduced dramatically compared to the legacy PF2A. The 3-digit LED display can be red or green, changing when a set point is reached. Either instantaneous or accumulated flow can be shown. Options include inline or bottom piping entry, cable connector type, a manual flow adjustment valve, and panel or bracket mounts. Two outputs are available, including two switch signals, or a switch and analog signal. PFMB is IP40 rated, and C-UL-US, CE and RoHS compliant.
