What does a pressure transducer do?
A pressure sensor (Pressure Transducer) is a transmitter that can sense pressure signals and convert them into usable output electrical signals according to certain rules.
The pressure sensor usually consists of a pressure sensitive element and a signal processing unit. According to different test pressure types, pressure sensors can be divided into gauge pressure sensors, differential pressure sensors and absolute pressure sensors.
How do you test a pressure transducer?
Today I will mainly introduce three common detection methods for pressure sensors. Hope it helps everyone.
1. Pressure test. The method of detection is to power the sensor. Use your mouth to blow the air hole of the pressure sensor. Use the voltage file of a multimeter to detect the voltage change at the output of the sensor. If the relative sensitivity of the pressure sensor is large. This amount of change will be obvious. If nothing has changed. You need to use a pneumatic source to apply pressure instead.
2. Zero point detection. Use the voltage file of a multimeter. Detect the zero output of the sensor under no pressure. This output is generally mV level voltage. If the technical specifications of the sensor are exceeded, the zero deviation of the sensor is out of range.
3. Detection of bridges. It mainly detects whether the circuit of the sensor is correct. It is generally a Wheatstone full-bridge circuit. Use the ohm file of the multimeter to measure the impedance between the input terminals and the impedance between the output terminals. These two impedances are the input and output impedances of the pressure sensor. If the impedance is infinite, the bridge is disconnected. It means there is a problem with the sensor or the definition of the pin is not correct.
How does a 3 wire pressure transducer work?
The output signal of the two-wire pressure transmitter is generally 4-20MA. The supply voltage is 24VDC. The two wires are a red (representing positive 24V power supply), and a black or blue (representing positive signal output). The wiring method is that the red wire is connected to the positive source and the blue wire is connected to the signal positive, and then the power supply negative and the signal negative are shorted.
The three-wire pressure transmitter is generally a voltage output. Wire one (red power supply is positive), one black (power supply is negative), and one yellow (signal output is positive). The output ground is common to the power supply.
Why shouldn’t you use a pressure transducer with high oxygen environment?
Oxygen plays an important role in the smelting process, chemical industry, national defense industry, and healthcare. However, the process of oxygen production and use is extremely prone to combustion and explosion.
The analysis is based on the mechanism of the “three elements” of combustion and explosion (combustible materials, oxidants, and excitation energy). The high-purity high-pressure oxygen transported in the oxygen pipeline is a very strong oxidant. The higher the purity, the higher the pressure, the stronger the oxidation, the more dangerous.
The potential sources of excitation energy for combustion or explosion are roughly the following: friction, compression heat, impact force, arc, resonance, etc.
In the construction of industrial oxygen pipelines, multiple cleaning processes such as derusting, scrubbing, sand blasting, blowing, degreasing, and acid cleaning should be carried out. Remove the oil and impurities in the pipeline to make it reach the condition of transporting oxygen medium. Check and accept according to relevant standards, and use it after passing the test.
For oxygen pressure measurement, choosing a clean instrument filled with inert oil not only improves the safety level, but also greatly reduces the risk of economic and time loss caused by maintenance or failure replacement.
