Digi Mag Differential Pressure Gauge 0.50-0-0.50 in H20

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 DigiMag 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. Digi Mag 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.

Accurate and Reliable Readings

With 1% full-scale accuracy and a fast 1-second update rate, the DM-1123 ensures trustworthy, real-time differential pressure measurements. Suitable for both laboratory and field use, this gauge provides stable, repeatable results without analog output, emphasizing display clarity and precision.

Flexible and User-Friendly Operation

Selectable units for in H2O, mm H2O, Pa, and kPa enable versatile applications across varied measurement requirements. The digital zero adjustment is quick and convenient, streamlining setup and ongoing calibration. Designed for straightforward integration, the units surface or panel mount configuration suits a wide range of installation scenarios.

Durable and Industrial-Grade Build

Housed in a robust, textured ABS plastic case and sealed with Buna-N for added safety, the gauge withstands operating temperatures from 0 to 60C and overpressures up to 10 psi. IP54 equivalent ingress protection shields it from dust and moisture, making it ideal for industrial environments.

FAQs of Dwyer USA DM-1123 Digi Mag Differential Pressure Gauge:

Q: How is the Dwyer DM-1123 differential pressure gauge calibrated and zeroed?

A: Calibration is simplified with its push-button digital zero adjustment. This feature allows users to quickly set the baseline pressure reading, ensuring accuracy before each use without the need for manual calibration equipment.

Q: What media can the DM-1123 measure pressure of, and are there limitations?

A: The unit is designed to measure differential pressure of air and other non-corrosive gases only. It should not be used with corrosive substances or liquids to avoid damaging the sensor and internal components.

Q: When should I replace the battery in this gauge, and what type does it require?

A: The DM-1123 operates on a standard 9V alkaline battery. Replace the battery as soon as display performance drops or as indicated by the gauges battery alert, typically after extensive periods of continuous use.

Q: Where can this pressure gauge be mounted, and what mounting options are included?

A: This model supports both surface and panel mounting. The package includes a sturdy mounting bracket, enabling secure installation on flat surfaces or within equipment panels as required in industrial settings.

Q: What is the process for changing pressure measurement units on the DM-1123?

A: Pressure units are selectable via the user interface on the digital display. Users can switch between in H2O, mm H2O, Pa, and kPa effortlessly during operation or initial setup.

Q: How does the lack of analog output affect integration with monitoring systems?

A: As a display-only model, the DM-1123 does not provide analog output for remote monitoring. For applications requiring data transmission to external systems, users should consider gauges with analog or digital outputs.
