Advantages of Waterproof Pressure Transmitters
The installation of a waterproof and breathable membrane can not only allow the external air of the locomotive pressure transmitter to enter the interior of the pressure transmitter and work normally, but also effectively prevent external moisture from entering the interior of the locomotive pressure transmitter. Ensure the pressure inside the transmitter The sensor will not fail to function due to the humidity of the external environment.
Setting up a waterproof and breathable membrane can maintain the balance of internal and external air pressure, thus ensuring the consistency of the product under atmospheric pressure in various places, thereby ensuring the correct measurement.
If the pressure sensor is located at the bottom of the measuring range, for example at the bottom of a tank, the pressure is proportional to the height of the liquid directly above it.
If the tank is vented, the pressure sensor can also be configured as a vented gauge measurement type, correcting for changes in air pressure through the vent tube in the cable.
A pressure sensor can be used to measure tank pressure.
Installed at the lower end of the water storage container, the measured pressure is the water pressure.
If it is a pressure sealed water storage container. Differential pressure sensors can be installed at the uppermost and lowermost ends of the container. The measured pressure is the water pressure.
Fluid pressure sensors are mainly used in: construction machinery, hydraulic and pneumatic systems, petrochemical, energy and water treatment, water conservancy and hydropower, compressors and other fields.
For example: fluid pressure sensors are used in hydraulic systems.
The pressure sensor is mainly used in the hydraulic system to complete the closed-loop control of the force.
When the control spool moves suddenly, a peak pressure several times the system working pressure will be formed in a very short time.
In typical mobile and industrial hydraulics, any pressure sensor would quickly be destroyed if it was not designed for such extreme conditions. Shock-resistant pressure sensors are required.
There are two main methods for the pressure sensor to achieve impact resistance, one is to change the strain gauge chip. Another method is to connect external coils.
Generally, the first method is adopted in the hydraulic system, mainly because of the convenience of installation. Another reason is that the pressure sensor is subjected to constant pressure pulsations from the hydraulic pump.

The pressure sensor can monitor the water pressure at the pressure measuring point of the water supply pipeline.
For example, 7 electromagnetic flowmeters are installed on the main network of the urban water supply area, and a pressure sensor monitoring device is installed at the same time. Use big data to monitor and judge the operation of the urban water supply network in real time. Realized water volume, water pressure on-line monitoring and whole-process monitoring.
Water pressure sensor is a kind of pressure sensor commonly used in industrial practice. It is widely used in various industrial dynamic environments, water conservancy and hydropower projects, transportation and construction equipment, production automatic control systems, aerospace technology, ship technology, transportation pipelines and other areas.
The core of the water pressure sensor is usually made of diffused silicon. The working principle is that the pressure of the measured water pressure acts directly on the diaphragm of the sensor. Make the diaphragm produce a micro-displacement proportional to the water pressure. Change the resistance value of the sensor. and electronically detect this change. And convert and output a standard measurement signal corresponding to the pressure.
Sino-Inst is a manufacturer of Waterproof Pressure Sensors. We supply more than 15 types of Waterproof Pressure Sensors.
There are many types of pressure sensors, such as resistance strain gauge pressure sensors, semiconductor strain gauge pressure sensors, Silicon piezoresistive pressure sensors, inductive pressure sensors, capacitive pressure sensors, resonant pressure sensors and capacitive sensors.
The waterproof pressure transmitter adopts high-precision and high-stability chip assembly of imported stainless steel isolation diaphragms. The product is manufactured through precise structural design, reasonable temperature compensation, linear processing circuit, V/I conversion and fully sealed welding process for stainless steel shell.
