About DWYER USA DPG-200 Digital Pressure Gauge

DWYER USA DPG-200 Digital Pressure Gauge

Series DPG-200 Digital Pressure Gage, 14.70-0

The SERIES DPG-200 Digital Pressure Gage has a precise ±0.25% full scale accuracy. The 4 digit digital display will reduce the potential for errors in readings by eliminating parallax error commonly produced with analog gages. The DPG-200 is packaged in a durable extruded aluminum case designed to meet NEMA 4X (IP66). The unit is powered by 12-24 VDC/VAC and contains two alarm set points along with a 4-20 mA process output. A four-button keypad allows easy access to features. These features include backlight, peak and valley, auto zero and conversion of the pressure units.

The included 9V alkaline battery lasts up to 2000 hours, and the device allows for simple field recalibration as needed. Factory-calibrated for immediate use out of the box, it also includes a protective boot, instruction manual, and maintenance is minimal thanks to its digital design and rugged build.

FAQs of DWYER USA DPG-200 Digital Pressure Gauge:

Q: How do I operate the DWYER DPG-200 Digital Pressure Gauge?

A: Simply connect the gauge using its 1/4 NPT male fitting to your equipment, power it with the included 9V battery, and select your preferred pressure unit on the digital display. Use the on-panel zero button to ensure accurate readings before use.

Q: What types of media can this digital pressure gauge measure?

A: The DPG-200 is suitable for measuring the pressure of air, gases, and non-corrosive liquids. It is not intended for corrosive or aggressive media that could damage the internal sensor or seals.

Q: When should I recalibrate the DPG-200, and how is it done?

A: Periodic recalibration is recommended depending on usage frequency and accuracy requirements. The DPG-200 is factory calibrated but allows field recalibration using appropriate reference standards, ensuring continued measurement reliability.

Q: Where can this pressure gauge be used effectively?

A: Thanks to its IP67 water and dust resistance and shockproof rubber boot, the DPG-200 performs reliably in industrial, laboratory, and field environments, including outdoor or harsh conditions where durability is essential.

Q: What are the main benefits of using the DPG-200 over analog gauges?

A: The DPG-200 offers higher accuracy, digital data readings (including peak/min hold), easy unit switching, durability, and minimal maintenance. The backlit display and data hold features enhance usability, especially in low-light or complex scenarios.

Q: How long does the battery last, and how do I know when to replace it?

A: The included 9V alkaline battery lasts up to 2000 hours. If the display dims or readings are unstable, it is time to replace the battery, which is a straightforward process following the instruction manual.

Q: What process is required for installation and usage?

A: Installation involves connecting the gauge via its threaded port, ensuring sealing with the NBR gasket if required. Power on, select the desired unit, and confirm zero adjustment before taking readings. Minimal calibration and maintenance make the process user-friendly.
