Dwyer Series DM-1000 DigiMag® Digital Differential Pressure and Flow Gages

 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 DM-1000 DigiMag® Digital Differential Pressure and Flow Gages monitor the pressure of air and compatible gases just as its famous analog predecessor the Magnehelic® Differential Pressure Gage. All models are factory calibrated to specific ranges. The 4-digit LCD can display readings in common English and metric units so conversions are not necessary. The simplified four button operation reduces set up time and simplifies calibration with its digital push button zero and span.

Features

• Field programmed reduces installation time
• User selectable parameters for pressure, air velocity or flow permits same device for multiple applications
• Specialized filter set point for alerts when maintenance is due
• Security levels permit matches the correct access to right skill
• Power versatility works with 9-24 VDC or 9 V battery allows deployment in a variety of spaces wired or not

Application

• Filter monitoring
• Air velocity or flow
• Blower vacuum monitoring
• Fan pressure indication
• Duct, room or building pressures
• Clean room positive pressure indication
