DWYER DM-1104 DIGIMAG DIFFERENTIAL PRESSURE GAUGE

DigiMag Differential Digital Pressure Gage,Range 0-1.00WC

The DigiMag 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. 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.

Versatile Installation and Operation

Designed for flexibility, this gauge can be mounted either horizontally or vertically and fits standard panel cutouts. With screw terminal block connections and a polycarbonate, matte-finish enclosure, installation is straightforward and maintenance is minimal.

Advanced Features and Compliance

The DM-1104 offers advanced capabilities, including push-button zero adjustment and optional analog outputs for system integration. It meets CE and RoHS standards, providing assurance of quality and safe operation in commercial and industrial settings.

FAQs of DWYER DM-1104 DIGIMAG DIFFERENTIAL PRESSURE GAUGE:

Q: How do you reset the zero point on the DWYER DM-1104 Differential Pressure Gauge?

A: Zero adjustment is performed easily using the push-button located on the device. Ensure the gauge is vented to ambient pressure before pressing the push button to guarantee accurate resetting.

Q: What environments is the DM-1104 suitable for?

A: This device is ideal for use in HVAC systems, air handling units, clean rooms, and ducts. Its IP54-rated enclosure and wide operating and storage temperature ranges make it suitable for industrial applications requiring measurement of air or non-corrosive gases.

Q: When should the optional analog output be used?

A: The optional analog output (0-5 V or 4-20 mA) should be used when you require real-time monitoring, control integration with building automation or process management systems, or remote data logging.

Q: Where should the DM-1104 be mounted for optimal performance?

A: For best results, the gauge should be panel-mounted in either a horizontal or vertical orientation as per your system design. The included mounting bracket and installation manual provide detailed instructions for secure installation.

Q: What is the process for connecting power and signal wiring to the DM-1104?

A: All electrical connections are made via the screw terminal block. Carefully follow the installation manual to connect the 9-30 VDC power supply and, if needed, configure the optional output terminals for signal transmission.

Q: How does using the DM-1104 benefit HVAC and cleanroom monitoring?

A: With its fast response, high accuracy (2% full scale), and robust construction, the DM-1104 ensures reliable monitoring and control of air pressure. This helps maintain optimal operational conditions, improves energy efficiency, and supports compliance with cleanroom and HVAC standards.
