Diffused Silicon Pressure Transmitter Selection Guide
When selecting a diffused silicon pressure transmitter, it is recommended that you consider the following factors:
- Measuring range: Select the appropriate measuring range based on the actual measured pressure range. If the actual measured pressure value may exceed the range, a transmitter with a larger range needs to be selected to avoid damage.
- Accuracy level: The accuracy level of diffused silicon pressure transmitters is usually between 0.1% and 0.5%. Select the appropriate accuracy level according to the actual measurement accuracy requirements. The higher the accuracy level, the higher the price.
- Temperature range: The operating temperature range of the diffused silicon pressure transmitter is generally between -40℃~85℃. The actual working environment temperature needs to be considered when selecting to ensure that the transmitter can work normally within a certain temperature range. We support high temperature and low temperature customization.
- Media compatibility: The diaphragm material and sealing material of the diffused silicon pressure transmitter need to be compatible with the measured medium. Select the appropriate transmitter diaphragm and sealing material according to the actual properties of the measured medium (such as corrosiveness, viscosity, etc.).
- Output signal: The output signal of the diffused silicon pressure transmitter is generally an analog signal of 4~20mA or 0~5V. Select the appropriate output signal type and specifications according to actual needs.
- Explosion-proof level: If it is used in explosive, flammable and other dangerous environments, you need to choose an explosion-proof diffused silicon pressure transmitter and ensure that it meets the relevant explosion-proof standards.
- Installation method: Choose the appropriate installation method according to the actual installation environment and space. Such as guide rail installation, bracket installation, etc. Ensure easy installation, firmness and reliability.
Of course, you can also contact our sales engineers directly. We will select the appropriate pressure transmitter based on your measurement conditions.
What is an electronic pressure transmitter?
Electronic pressure transmitter is a device that converts pressure into electric signals for control and remote transmission. It can convert physical pressure parameters such as gas and liquid sensed by the load cell sensor into standard electrical signals (such as 4~20mADC, etc.) to supply secondary instruments such as indicating alarms, recorders, and regulators for measurement and indication. and process regulation.
Most of the industrial pressure transmitters we use now are Electronic pressure transmitters.
What are the four types of pressure transmitters?
There are many ways to classify pressure transmitters. Here we classify them according to the measurement principle.
There are four common pressure sensors:
1. Strain gauge pressure sensor
Strain pressure sensors are sensors that measure pressure mainly by measuring the strain of elastic elements. Depending on the materials used, strain elements are divided into metals and semiconductors. When conductors and semiconductor materials are mechanically deformed, their resistance changes.
2. Piezoresistive pressure sensor
The piezoresistive pressure sensor is a sensor made of the piezoresistive effect of single crystal silicon material and integrated circuits. When the single crystal silicon material is subjected to force, the resistivity will change. At this time, through the measurement circuit, an electrical signal proportional to the change in force will be output.
3. Capacitive pressure sensor
Capacitive pressure sensors mainly use capacitors to convert the measured pressure into a pressure sensor that changes the capacitance value. The electrodes of the capacitor should be round metal films or metal-plated films. The membrane deforms when it experiences pressure. At this time, the capacitance changes and an electrical signal is formed.
4. Piezoelectric pressure sensor
Piezoelectric pressure sensors use the piezoelectric effect. Use electrical components and other machinery to convert pressure into electricity. Instruments for related measurement work.
