Electronic pressure gauge for measuring pressure

Manometers are created to measure the pressure values of gas and water. On the functional part, the instruments are quite different. By design, they can also be different. In this case, it is important to consider the model manufacturer.

Displays in devices are installed the most diverse. To date, there are both black and white, as well as color modifications. The number of buttons for control depends on the functionality of the device. In order to get a deeper understanding of this issue, it is necessary to disassemble the main types of manometers.

Automobile modifications for tires

High-precision automobile gauges are distinguished. However, the reverberator pressure is capable to hold a maximum of 900 bar. In this case, management fees are set very different. Some models are equipped with controller units. By function, the manometers are quite different. Many of them are able to fix the values. Also there are devices with a barometric option. With the function of automatic testing of pressure gauges there is little.

Gas manometer

Gas manometers are manufactured with selective reverbs. In this case, the instrument's accuracy factor does not exceed 0.2 IW. On the displays the models differ. On average, the electronic pressure gauge for gas pressure is capable of withstanding at 650 bar. Some modifications can be connected to a personal computer. Expanders for models are installed with different sensitivity.

Water model

There are a lot of water manometers on the market. The housings of these instruments are well protected and do not let moisture pass. Also on the market there are many shock-resistant modifications. The display of water pressure gauges, as a rule, is set to a small size. The function of fixing the value is available in all devices. Their filters are of the grid type. On average, the pressure of an electronic water manometer is capable of withstanding 1200 bars.

Devices with a barometric function

Devices with a barometric function are sold with displays of different resolutions. Chips for models are most often used three-channel type. Reverb, in turn, is only suitable for magnetic. Filters in these devices can be installed very different. If we talk about the parameters, the pressure of the devices is maintained at 700 bar. The error in this case does not exceed 0.2 IV.

Some models have a connector for connecting a personal computer. Use devices are capable even at a temperature of -10 degrees. However, it is important to take into account the shortcomings of manometers of this type. First of all, we are talking about the low sensitivity of the device. In this case, expanders are installed, as a rule, at 5 microns. All this suggests that models with large pressure values can give a large error.

Devices with the option of automatic testing

An electronic manometer for measuring this type of pressure in our time is very rare. Chips for models fit three- and four-channel. Directly the reverbs are installed in a closed type. By the interface of the model can be very different. Sensitivity augers have an average of 6.6 microns. In this case, the control units are of different design.

If we consider modern modifications, then special zener diodes are installed there. The signal is transmitted directly by using reference diodes. Resonators on the characteristics are quite different. On the average, the error in gauges of this type does not exceed 0.3 IV. Use the device for frost and heat.

Manometers with storage devices

Manometers with memory devices are often used in the industrial sphere. They are also great for carrying out various experiments. Directly, microcircuits for devices are often selected four-channel type with output to a personal computer. Reverb can be found both open and closed.

The filters for the models are modular. Taking into account all the above, the accuracy of measurements in instruments is fairly high. However, to temperature conditions they are very demanding. In turn, the moisture resistance of the manometers of this type are very different.

Models on dual-channel chips

An electronic digital manometer on a two-channel chip is able to accurately determine the pressure. Most often models of this type are installed with built-in reverbs. Directly filters are used modular type. With respect to the accuracy parameter, the models can be quite different.

This threshold is also affected by the threshold pressure that the device can withstand. Tetros in this case are not available in all manometers. It is also important to note that the reference diodes in devices are installed on a conductor base. Resonators for today are very diverse.

Application of three-channel microcircuits

Three-channel chips allow first of all to connect a manometer to a personal computer. On the functional part of the device are very different. Reverbs are usually of an open type. On sensitivity, the expanders are not much different. On average, this parameter fluctuates around 6.5 microns. Controllers can be found with or without zener diodes.

Accutire Pressure Gauges

The electronic tire gauge Accutire is equipped with a three-channel microcircuit. In this case, management is quite simple. Directly reset function is available. There is no built-in memory for this model. The sensitivity of measurements is at the level of 0.2 IV. Directly the connector under the PC is available.

To the ambient temperature, this electronic pressure gauge is very demanding. The case is not moisture-resistant in this case. If we talk about design features, it is important to note that the reverb manufacturer provides a modular type. The controller unit itself is available without a zener diode. The reference diodes in the manometer are set to three. The resonator is used for low sensitivity.

Model Accessories

This tire manometer (electronic) is distinguished by a high-sensitivity resonator. The function of automatic testing in the device is provided. The interface in this case is PP20. The reference diodes for signal transmission are set to three.

The control unit is used without a zener diode. However, the chip has a three-channel type. It is also important to mention that the model has an interrupt mechanism. If necessary, you can turn off the pressure gauge very quickly. The system pressure is maintained at a maximum of 850 bar.

Features of BMW pressure gauges

This electronic pressure gauge is equipped with an interrupt mechanism. In this case, the resonator is used with moderate sensitivity. Up to 500 bar the error of the device is equal to 0.3 IW. The connector for connecting to a PC in the device is missing. The model can be operated at a maximum temperature of +45 degrees. The barometric function of this gauge is not provided. Filters for the model are only modular.

This electronic gas manometer is made on the basis of a three-channel microcircuit. In this case, the reverb is an open type. In turn, the filter is installed modular. There is no interrupt mechanism for this device. It should also be noted that the expander in the manometer is used for two contacts. According to the documentation on the device, its sensitivity is equal to 5.5 microns.

The control unit for control is used with a zener diode. In this case, this electronic manometer has the fixation function. There are three reference diodes in the device. For better signal transmission, a special tetrode is used. The interface for the model is P232. The resonator is presented with good conductivity. If we talk about the parameters of the manometer, then first of all it is necessary to indicate the error of the model.

At the same time, the system is able to withstand a pressure of at most 900 bar. A connector for a personal computer is provided for the model. The temperature compensation index ranges from -15 to +40 degrees.
