Flat Pressure Sensor is a type of pressure sensor that specifically refers to the measurement diaphragm without pressure holes. Also known as a flat film pressure sensor.

Flat Pressure Sensor is a special pressure sensor most commonly used in industrial automatic control. It is widely used in the pressure measurement and control of viscous media such as chemical coatings, paints, mud, asphalt, crude oil, etc. It solves the problem that conventional products are easy to block and cannot be used continuously, etc. defect.

The Flat Pressure Sensor elastomer adopts imported materials, diaphragm isolation technology, no pressure holes in the test head, and no viscous medium clogging during the measurement process.

Principle of Flat Pressure Sensor

The flat membrane pressure sensor test head adopts the pressure-free mode to ensure that there is no blockage of viscous media during the measurement process, and to ensure that the pressure detection works normally.

It adopts super-large diaphragm design, the core adopts highly sensitive material, diaphragm isolation technology, and integrated structure design.

The medium and high temperature pressure-sensitive chip and heat pipe structure are used in the measurement of high temperature medium, which effectively solves the drawbacks that the electronic components inside the sensor cannot withstand high temperature.

Frequently
Asked
Questions

pressure transducer often called a pressure transmitter, is a transducer that converts pressure into an analog electrical signal.

Although there are various types of pressure transducers, one of the most common is the strain-gage base transducer.

The conversion of pressure into an electrical signal, is achieved by the physical deformation of strain gauges, which are bonded into the diaphragm of the pressure transducer, and wired into a Wheatstone bridge configuration.

Pressure applied to the pressure transducer produces a deflection of the diaphragm, which introduces strain to the gages.

The strain will produce an electrical resistance change proportional to the pressure.

Fluid Pressure Sensors refers to sensors that can be used to measure the pressure of liquid media. Such as measuring pressure of Oil, Fuel and other fluid systems (select a sensor with the appropriate range for your system). Fluid Pressure Sensors have important uses. For example, the direct measurement of pressure in a fluid line. For example, put Fluid Pressure Sensors into the liquid, measure the liquid pressure, and estimate the liquid level. For example, by measuring the differential pressure of Fluid, the flow rate of the pipeline can be calculated.
