DM-1124 DigiMag® differential digital pressure gage, range 2-0-2" w.c.

The Digi Mag Series DM-1000 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. The Digi Mag Digital Gages are more versatile than analog gages with their ability to be field-programmed to select pressure, air velocity or flow operation depending on model. The DigiMag Digital Gages have an added feature for filter applications where a set point can be input where the display will blink when the filter is dirty, alerting the user that a maintenance action needs to occur. Programming the Series DM-1000 is easy using the menu key to access 4 simplified menus which provide access to, depending on model: security level; engineering units; K-factor for use with various Pitot tubes and flow sensors circular or rectangular duct size for volumetric flow operation; filter set point; view peak and valley process readings; digital damping for smoothing erratic process applications; display update to conserve battery life; zero and span field calibration. The Series DM-1000 DigiMag Digital Differential Pressure and Air Flow Gages possess a full-scale accuracy of 1% on ranges down to 2 in H2O and 2% accuracy down to the very low range of 1 inch to 0.25 in H2O. DigiMag Digital Differential Pressure Gages offer power versatility by working with 9-24 VDC line power or simply 9V battery power. If using line power and connecting the 9V battery, the battery will act as a back-up if line power is lost or interrupted.

Advanced and User-Friendly Design

The DM-1125 is crafted for both precision and convenience, featuring a user-friendly push-button zero adjustment, clear 4-digit digital display, and easy push-on tubing connectors. Its anodized aluminum front panel and polycarbonate housing provide robust protection, while the power flexibility supports different installation setups. Mounting is streamlined with included hardware, ensuring hassle-free wall or surface placement.

Reliable Accuracy and Fast Response

Engineered with a digital differential pressure sensor and solid-state microprocessor, the DM-1125 delivers an impressive accuracy of 1% full-scale and a typical response time of just 1 second. This makes it highly effective in environments where quick, reliable pressure readings are critical for maintaining operational safety and efficiency.

FAQs of Dwyer USA DM-1125 Digi Mag Differential Pressure Gauge:

Q: How do I install the DM-1125 Digi Mag Differential Pressure Gauge?

A: Installation is straightforward. Mount the gauge onto a flat wall or surface using the provided screws and rubber grommets. Connect your pressure lines to the push-on tubing connectors (compatible with 1/8 NPT female threads). Ensure it is powered by either a 924 VDC supply or a 9V battery before use.

Q: What is the recommended process to perform a zero adjustment?

A: With the DM-1125 powered on and both pressure ports open to atmospheric air, press the push-button zero adjustment to calibrate the display to zero. This should be done before each use for optimal accuracy, especially if temperature or position has changed.

Q: Where can I use the DM-1125 pressure gauge effectively?

A: This gauge is designed for monitoring differential air and compatible gas pressures in industrial, HVAC, cleanroom, and laboratory settings. Its IP54 rating allows use in environments where moderate dust and moisture protection are necessary.

Q: What are the main benefits of using this digital pressure gauge over analog options?

A: The DM-1125 provides digital accuracy (1%), rapid 1-second display updates, easy zeroing, and better readability with its 4-digit LCD. Unlike analog Bourdon tube gauges, it is less prone to drift and can be recalibrated quickly.

Q: When should I replace the battery, and how do I know if power is low?

A: Battery life depends on usage, but the gauge will indicate low power on the digital display. Replace the 9V battery when you observe diminished display clarity or a low battery icon. Alternatively, use a stable 924 VDC power supply for continuous operation.

Q: What pressures and media are suitable for measurement by the DM-1125?

A: It is suitable for measuring differential pressures of air and non-corrosive, compatible gases within the 0125 Pa range. It is not intended for liquids or aggressive gases that could damage its neoprene seals or sensor.
