Digital Pressure Gauges

Intelligent digital Pressure Gauges have full electronic structure and use battery-powered. The intelligent digital pressure gauges have some benefits as follows: flexible use, simple operation, easy debugging, safety, reliability and so on. So they have been widely used in hydropower, water, so they are very easy for on-site installation. Specifically, front-end high-precision piezoresistive pressure sensor is used and the output signal is processed by the high-precision, low temperature drift amplifier, then sent into the high-precision A/D converter to be converted into digital signal, after computing and processing the actual pressure value is showed on the LCD display.

Advantages of CG Digital Pressure Test Gauge

Our calibrated digital hydraulic pressure gauges are miniature smart product applied with international dinosaur measurements and accurate temperature proof. The pressure value can be measured continuously and realistically since our digital pressure gauge has high accuracy. It is very suitable for on-site and laboratory use, to complete precision pressure measurement, general pressure gauge, precision pressure measurement, etc. The working table of the pressure instrument can also be widely used in occasions requiring precise pressure measurement. It is also a replacement of traditional medical pressure gauges such as medical pressure precision gauges and electric contact pressure gauges. What’s more, our digital water pressure gauge with data logger will record peaks automatically. It has high stability with good temperature compensation and time drift. Our pressure gauge digital display is internationally accepted with 11 kinds of pressure unit conversion, such as MPa, kPa, Pa, mbar, bar, psi, mmH2O, mmHg, inH2O, inHg, kgf/cm2. The power supply methods of our digital pressure test gauge are also various whether you use a battery or a power adapter.


Digital Hydraulic Pressure Gauge VS Digital Air Pressure Gauge

The digital Hydraulic Pressure Gauge and digital Air Pressure Gauge generally can be used interchangeably (that is, the commonly used hydraulic oil and air medium can be used interchangeably), as long as the range and accuracy of the digital gauge are satisfied. But if it is a corrosive medium, such as oxygen and hydrogen, the digital pressure tester for ammonia gas cannot be interchanged with the pressure gauge for hydraulic oil. Generally, the gas medium is measured at a relatively low pressure, but there are also high-pressure gases, especially military products. Gases of tens of MPa can also be measured. The range of the pressure digital meter cannot determine what medium is being measured.


Digital Pressure Test Gauge Working Principle

The digital pressure test gauge uses the analog-digital conversion principle to convert the measured voltage into a digital quantity, and the measurement result is displayed in digital. To be specific, the digital pressure test gauge uses a pressure sensor to convert the pressure into an electronic signal. The most commonly used sensor is a piezoresistive pressure sensor which is equipped with a diaphragm of many piezoresistive elements. When the medium of a digital high pressure gauge is under pressure, it will cause a change in the cross-sectional area of the piezoresistive element because of the deflection of the diaphragm, then the coupled resistor will detect the change. Generally there are 2 gauges of a digital water pressure meter, one is to indicate the total pressure (reading a little higher), the other is to indicate the chuck pressure (reading a little lower), if there is a tail seat, then one more pressure gauge. It’s very simple to distinguish, step on the foot switch or press the switch on the panel to make the chuck open, there should be a moving table pointer, this is the chuck hydraulic meter; the one that doesn't move is the general pressure gauge.

How to Choose Digital Pressure Gauge

When choosing a digital pressure gauge, there are several factors to consider to ensure you select the right one for your needs. Here are some important points to keep in mind:

Pressure Range: Determine the pressure range you need to measure. Digital pressure gauges come with different pressure ranges, so it's crucial to select one that can handle the specific pressures you intend to measure.

Accuracy: Consider the required accuracy for your application. Different gauges have varying levels of accuracy, so choose a gauge that meets your precision requirements.

Display: Check the display of the digital pressure gauge. Ensure that it has a clear and easy-to-read digital display that shows the pressure values accurately. Consider factors such as the size of the display, backlighting, and any additional features like graphs or data logging.

Units of Measurement: Verify if the gauge supports the units of measurement you require. Digital pressure gauges can display pressure readings in various units, such as psi, bar, kPa, or others. Make sure the gauge offers the unit of measurement you need.

Pressure Connection: Evaluate the pressure connection compatibility. Consider the type of pressure connection required for your application, such as NPT, BSP, or other specific fittings. Ensure that the gauge you choose has a compatible connection mechanism.

Durability: Assess the durability and build quality of the gauge. Depending on your application, you may need a gauge that is resistant to certain environmental factors, such as moisture, dust, or extreme temperatures. Look for gauges with sturdy construction and suitable protection ratings.

Power Source: Determine the power source for the gauge. Some digital pressure gauges use replaceable batteries, while others have rechargeable batteries or are powered by an external power source. Consider your preference and the availability of power sources in your intended application.

Additional Features: Consider any additional features you may need. Some digital pressure gauges come with features like data logging, wireless connectivity, or the ability to store and recall pressure readings. Assess these features based on your specific requirements.

Price: Set a budget for the digital pressure gauge. Compare prices and features of different models to find one that offers the best value for your needs.

Brand and Reviews: Consider the reputation of the brand and read customer reviews. Look for gauges from reputable manufacturers known for producing reliable and accurate instruments. Customer reviews can provide valuable insights into the performance and usability of a specific gauge.

By considering these factors, you can choose a digital pressure gauge that aligns with your requirements and provides accurate pressure measurements for your application.


Can Digital Pressure Gauge Be Used in Different Environments?

Yes, digital pressure gauge can be used in different environments. Digital pressure gauges are designed to measure and display pressure accurately and can be used in a variety of applications and industries.

One of the advantages of digital pressure gauges is their versatility. They can be used in both indoor and outdoor environments, as they are often designed to be durable and resistant to environmental factors such as temperature, humidity, and dust. However, it's important to note that not all digital pressure gauges are suitable for all environments. Some gauges may have specific environmental ratings or limitations, so it's crucial to choose a gauge that is appropriate for the specific conditions in which it will be used.

For example, there are digital pressure gauges available that are specifically designed for harsh or extreme environments, such as those found in the oil and gas industry or industrial manufacturing processes. These gauges may have features like rugged casings, high IP (Ingress Protection) ratings to protect against dust and water, and resistance to vibrations or shocks.

On the other hand, there are also digital pressure gauges that are more suitable for clean and controlled environments, such as laboratories or medical applications. These gauges may have a higher level of precision and accuracy but may not be as rugged or resistant to harsh conditions.

Before using a digital pressure gauge in a specific environment, it's essential to review the manufacturer's specifications, ratings, and guidelines to ensure that the gauge is suitable for the intended use. Additionally, proper installation and regular maintenance are important to ensure accurate and reliable measurements in any environment.
