Product details
The digital pressure gauge produced by our company adopts imported MCU and high resolution AD converter, which can meet the requirements of high precision and low power consumption. Large screen LCD display, data clear and easy to read. The shell is made of stainless steel, resistant to corrosion and mechanical pressure. The whole body adopts sealing technology, which can be applied in a variety of complex environments. A 2-year continuous lithium battery is an ideal alternative to a mechanical powered meter.

1. Process characteristics

2、 Main uses:
1. Oilfield water injection, pressure measurement of wellhead container equipment;
2. Crude oil export: pressure measurement at inlet and outlet of pipeline pump of power equipment;
3. Petrochemical Industry: vacuum, micro pressure and corrosive gas and liquid pressure measurement in production process;
4. Refrigeration, process monitoring system;
5. High temperature medium, viscous medium, liquid height measurement;
6. Pressure measurement of air conditioning, gas processing equipment, ventilator, medical equipment, laboratory, compressor, etc;
7. Other suitable places.


3. Operation instructions
The sensor and display processing part of the product adopts an integrated design structure, which is easy to use. The instrument and the measured mechanism are directly connected by thread, and there is no requirement for the placement angle of the instrument. Before using the measurement, the approximate pressure range of the measured target should be estimated, so as to avoid mechanical damage to the sensor due to excessive pressure beyond the measurement range. The pressure response time of this product is 1s.


4. Precautions
This product is a precision instrument, which uses liquid crystal display technology. If it is used in strong light, the service life of the LCD screen will be reduced, and the data may not be identified clearly. Our factory will not be responsible for the consequences of the accident. The silicon pressure gauge should be used to measure the pressure of the strong acid and alkali medium. This product uses non rechargeable lithium batteries. The used batteries should be properly treated (they can be sent back to our factory for unified treatment) to avoid environmental pollution. When used at high or low temperature (more than 50 ℃, less than - 10 ℃), heat sink should be added when the temperature is higher than 50 ℃. Otherwise, the accuracy of measurement cannot be guaranteed. Moreover, lithium battery may explode at high temperature. Attention should be paid to the instrument temperature during storage or transportation. As this product is an electronic product, it will cause the instrument failure when it is used in strong electromagnetic field, resulting in inaccurate indication or no display at all, but it will not cause essential damage to the instrument. Different instruments have different pressure measuring ranges. Under normal conditions, they can be used within 10% of the measuring range. If they are used beyond the range further, the mechanical damage of the sensor may be caused, and then the leakage of the measuring gas or liquid will be caused. This damage is irrecoverable. Our factory will not be responsible for any consequences caused by this.


Troubleshooting V
During the transportation and use of the product, due to environmental interference and improper operation, the instrument may not work and display normally. For simple faults, users can eliminate them by themselves, and other faults need to be returned to the manufacturer for maintenance. The following list shows the troubleshooting methods.
