The Ashcroft®GL42 low-differential pressure-indicating transmitter mates a four-digit LCD to Ashcroft’s existing low-differential pressure transmitter to provide a local reading as well as a 4- to 20-mA output. These features allow communication with a remote data acquisition device as well as a visual reading at the pressure source. Selectable engineering units, adjustable display response times, an IP65 enclosure, and several mounting options allow the GL42 to be applied to a variety of installations. Available ranges are from 0/0.1 to 0⁄25 inch H20 and bidirectional to ±30 inches H20.
