Metal Digital Pressure Gauge, Color : Blue

Listing ID #1897562

Digital pressure gauges, compared to their analog counterparts with dials and needles, offer a digital display for pressure readings and often come with additional features. Here's a breakdown of their typical specifications.

General Specifications

· Pressure Range: The range of pressure the gauge can measure, similar to other pressure transmitters (e.g., from fractions of psi to thousands of psi).

· Accuracy: Expressed as a percentage of full scale (%FS). Typical accuracy for good quality gauges is ±0.1%FS to ±0.5%FS.

· Display: Digital gauges provide a clear and easy-to-read digital readout of the pressure measurement.

· Pressure Units: They can often display pressure readings in various engineering units like psi, kPa, bar, mmHg, and more.

Performance Specifications

· Temperature Limits: The operating temperature range the gauge can withstand.

· Proof Pressure: The maximum pressure it can handle without permanent damage (typically 1.5 to 2 times the upper pressure range limit).

· Burst Pressure: The pressure that will cause catastrophic failure (typically 4 times the upper pressure range limit).

· Response Time: The time it takes for the display to update in response to a pressure change (usually faster than analog gauges, in milliseconds).

Additional Features

· Data Logging (Optional): Some gauges can store pressure data internally or on an external memory card for later analysis.

· Min/Max Recording: Some models can track and display the minimum and maximum pressure readings recorded during use.

· Calibration: Calibration is necessary to ensure accuracy. Some gauges offer features like user-friendly calibration routines.

· Battery Life: Battery-powered gauges typically specify their operating life on a single battery charge.

· Auto-Shutoff: A power-saving feature that automatically turns off the gauge after a period of inactivity.

· Backlight: A feature for improved visibility in low-light conditions.

· Enclosure Rating (IP rating): Indicates the level of protection against dust and water ingress (e.g., IP54 for dust resistance and splash water protection).

Factors to Consider When Selecting a Digital Pressure Gauge

· Pressure Range: Choose a gauge with a range that comfortably covers the pressure you intend to measure.

· Accuracy: Select a gauge with accuracy that meets your application's requirements.

· Features: Consider additional features like data logging, min/max recording, or backlight based on your needs.

· Environmental Conditions: Choose an enclosure rating suitable for the dust and moisture levels in your application environment.

· Portability: If portability is important, consider the size and weight of the gauge.

By understanding these specifications and factors, you can select a digital pressure gauge that offers the right combination of features, accuracy, and usability for your specific pressure measurement needs.
