Negative pressure sensor suitable for excavator YN52S00016P3

Differential pressure sensor is a kind of pressure sensor, which can measure positive pressure, differential pressure and negative pressure, but they have different methods in detecting pipeline connection. The negative pressure sensor is also a kind of pressure sensor, which measures the pressure value when the pressure to be measured is less than the predetermined pressure value.

1.Negative pressure sensor is the most commonly used pressure sensor in industrial practice, which is widely used in various industrial automatic control environments, involving oil pipelines, water conservancy and hydropower, railway transportation, intelligent buildings, production automation, aerospace, military industry, petrochemical, oil wells, electric power, ships, machine tools, pipeline air supply, boiler negative pressure and many other industries.

2.When the negative pressure side is the same as the atmosphere, the pressure measured on the positive pressure side is gauge pressure;

3.When the negative pressure side is sealed and evacuated, the absolute pressure is measured on the positive pressure side;

4.When the positive pressure side and the negative pressure side are respectively connected with the measured object, it measures the differential pressure between the sampled points of the measured object;

5.When the positive pressure side is the same as the atmosphere, what is measured on the negative pressure side is negative pressure, which can also be said to be vacuum.

1. Product structure

All-stainless steel sealing and welding structure adopts imported diffused silicon piezoresistive movement, high-precision stable amplification circuit and high-precision temperature compensation circuit, which has better accuracy and stability. The micro-pressure sensor adopts imported pressure-sensitive chip, and the shell adopts 316L stainless steel sealing and welding structure, which has good moisture-proof ability and excellent medium compatibility, and is suitable for measurement and control in occasions with weak medium pressure.

2 Second, product features

① The sensitivity coefficient of piezoresistive pressure sensor is 50-100 times larger than that of metal strain pressure sensor. Sometimes the output of piezoresistive pressure sensor can be measured directly without amplifier.

② Because it is processed by integrated circuit technology, its structure size is small and its weight is light.

③ High pressure resolution, which can detect micro-pressure as small as blood pressure.

④ The frequency response is good, and it can measure the pulsating pressure of several tens of kilohertz.

⑤ It is made of semiconductor material silicon. Because the force sensing element and detecting element of the sensor are made on the same silicon chip, it is reliable, with high comprehensive accuracy and long service life.

Stable performance, specially designed and produced for OEM customers.

The silicon sensor imported from Germany has excellent corrosion resistance, impact resistance, overload resistance, vibration resistance and wear resistance.

◇ Wide working temperature range, high comprehensive measurement accuracy and good long-term stability.

◇ Standardized design and production ensure the advanced nature, practicability and quality stability of products.
