Series 4000 Capsuhelic® Differential Pressure Gage

Known for quality, reliability and accuracy, Dwyer designs and manufactures a full-line of Controllers, Data Loggers, Gages, Manometers, Monitors, Remote Displays, Switches, Transmitters, and Accessories to measure, monitor and control pressure, air velocity, flow, fan pressure, duct, and more.

Dwyer’s wide selection extends to Gages, Transmitters, Switches, Data Loggers, and Monitors for Differential Pressure. Dwyer manufactures a range of dial and digital gages to reliably measure and display pressure difference, between two pressure sources using gas or liquid in a process flow.

Pressure, flow and piston-type gages are all found within this category. Clean design, small size and low cost with enough accuracy for all but the most demanding applications, these gages are the best around. Gages are indicators for the difference between two pressures or simply a single pressure.

The Series 4000 Capsuhelic® Differential Pressure Gage is designed to give fast, accurate indication of differential pressures. The gage may be used as a readout device when measuring flowing fluids, pressure drop across filters, liquid levels in storage tanks and many other applications involving pressure, vacuum or differential pressure.

The pressure being measured is held within a capsule which is an integral part of the gage.  This containment of the pressure permits the use of the gage on system pressures of up to 500 psig, even when differentials to be read are less than 0.1 in w.c.

Features

• Gage capsule permits high-pressure usage with small differentials
• Zero and range adjustments outside of gage means no disassembly in normal service
• Time-proven, simple, frictionless movement that permits full scale readings as low as 0.5 in w.c.
• Diaphragm-actuated versus liquid filled gage supports outdoor use

Application

• Fluid flow
• Liquid storage tanks
• Filter pressure drops
• Vacuum or differential pressure
