ABBITZ Model 399C Indicating Switch


   Barton® Model 288C Indicating Switch

ABBITZ Model 399C
Differential Pressure Indicator w/ Switch


The Model 399C DP Indicating Switches are used by Commercial, Industrial and Military for liquid level indication of Fuels, Oils, FLOX, CO2, Ammonia, Nitrogen, Helium, Hydrogen, Argon and many other fluids and gases. They are also used to measure Differential Pressure and Flow of those fluids and Gases with the ability of actuating a switch on increasing or decreasing differential pressures. Built as a drop in replacement for the Barton model 288, 288A and 288C, the ABBITZ 399C has the same form, fit and function. We have made some improvements on some of the internal components. A comparison of the Barton 288C and the ABBITZ 399C can be seen on the chart below.
