Benefits & Features

The new Ashcroft® Model GC52 is uniquely compact wet/wet differential pressure transmitter, ideal for flow and tank level applications where reliable, low dP measurements are required.

Equipped with the patented SiGlas™ 316 Stainless Steel isolated sensor, the GC52 can monitor a wide variety of wet or dry media.


Available in unidirectional ranges from 0-4 to 0-400 in.W.C and bidirectional ranges up to ±200 in.W.C., the GC52 operates on line (static) pressures up to 300 psi.  A rugged aluminum NEMA 4X / IP65 enclosure measures only 2.56 inches in diameter and incorporates a backlit LCD display for local reading.  The output is a two-wire configurable 4-20 mA signal that can be adjusted to re-range the transmitter or "tare" unwanted fluid head preloads.

In addition, this instrument offers flow measurement/square root extraction, where the momentary flow rate can be displayed and analog signal can be output.
