Digital Pressure Gauges
Intelligent digital pressure gauge chinahave 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 gaugesare 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 gaugeare 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.
