Dwyer Instruments DM-1124

DM-1124 DigiMag® differential digital pressure gage, range 1-0-1" 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.

Robust and Reliable Performance

With an IP65-rated enclosure and solid ABS construction, the DM-1124 Digi Mag Differential Pressure Gauge stands up to challenging environments. It measures differential pressure in air and non-corrosive gases, supporting a temperature range from 0 to 60C for operation and -20 to 70C for storage. Suitable for various applications, its industrial grade design ensures lasting reliability.

Intuitive Operation and Versatile Output

The DM-1124 features a user-friendly interface, including a pushbutton zero adjustment directly on the front panel and a clear LCD digital display. It also offers selectable output signals (420 mA or 010 V), allowing integration with different monitoring and control systems. High and low alarm settings are easily programmed for added safety and prompt alerts.

FAQs of Dwyer USA DM-1124 Digi Mag Differential Pressure Gauge:

Q: How is the DM-1124 Digi Mag Differential Pressure Gauge installed?

A: The DM-1124 can be surface or panel mounted using the included mounting screws. Its compact design and 1/8 NPT female thread make it compatible with standard piping configurations for monitoring air or non-corrosive gases.

Q: What types of output signals does this gauge provide for external systems?

A: It offers user-selectable output signals: either 420 mA or 010 V, which are compatible with most industrial data acquisition, monitoring, and control systems.

Q: When should the zero adjustment feature be used, and how does it work?

A: Zero adjustment should be performed during initial setup or when recalibration is needed. Simply press the pushbutton on the front panel to reset the gauge reading to zero, ensuring accurate measurements.

Q: Where is the DM-1124 typically used?

A: This gauge is ideal for use in industrial environments in India and worldwide, particularly for HVAC, process control, filtration monitoring, and clean rooms needing precise pressure differential readings.

Q: What is the process to set high/low pressure alarms?

A: High/low alarm thresholds can be configured by the user through the control interface, allowing the device to alert operators if pressure levels go outside the desired range for added safety and operational efficiency.

Q: How does the DM-1124 gauge benefit industrial applications?

A: It provides real-time, accurate differential pressure readings with a high-resolution display and versatile alarm functions, reducing downtime and enhancing the reliability of air or gas-based systems.
