Integrated shell vibration sensor universal SDJ705L

pressuretransmitterIn recent years, ininstrumentation and metersThe demand in the industry is constantly increasing, while at the same timeproductThe requirements for accuracy, stability, and price are also becoming stricter, which requires enterprises to constantly innovate and develop, and provide customers with better product user experience.

As a precision instrument, products play an important role in the petroleum and petrochemical industry. The transmitter can not only convert some commonly used quantities into expected demand electricity, but also amplify some commonly used quantities.

The main function of pressure transmitters is to apply pressure commonly used in petroleum and petrochemical industriessignalTeleport toelectronDevices, throughADConversion, reflected incomputerIn terms of operation, for example, taking water pressure as an example, the pressure signal generated by water pressure is transmitted to electronic devices to generate corresponding signalscurrentAt present, the current of most transmitters is 4-20mA. Through corresponding algorithm formulas, the converted current of the transmitter is also increased by the increase of the pressure signal generated by the pressure.

Macroscopically speaking, transmitters measure pressuresensorTo achieve the magnitude of pressure, and then through module circuits, AD conversion is achieved to obtain voltage or current within a usable range. From a microscopic perspective, pressure is reflected on integrated silicon pressure components, forcing them to deform under pressure and causing the bridge to act, resulting in corresponding voltage and current. The voltage and current obtained in the early stage are then amplified and converted into usable voltage or current through an amplification circuit.

Main performance of pressure transmitter:

1. Widely used as the tested medium, it can measure oil, water, and paste materials compatible with 316 stainless steel and 304 stainless steel, and has a certain degree of anti-corrosion ability;

2. High accuracy, high stability, using imported original sensors, good linearity, and high temperature stability;

3. Small size, light weight, easy installation, debugging, and use;

4. Stainless steel fully enclosed shell, with good waterproofing;

5pressure sensorDirectly sensing the pressure of the measured liquid level, without being affected by the foaming or deposition of the medium.

Features of pressure transmitter:

1. It has the ability to actively compensate for nonlinearity, temperature drift, and time drift of sensors through software. It can self diagnose and perform self inspection on the sensor after power on to check if all parts of the sensor are normal and make judgments. Data processing is convenient, and data can be actively processed according to internal programs, such as statistical processing, removal of abnormal values, etc.

2. It has bidirectional capabilitycommunicationFunction.microprocessorNot only can it receive and process sensor data, but it can alsoinformationReact to sensors to regulate and control the measurement process. It can store and recall information, including sensor feature data, configuration information, and compensation characteristics.

3. Having numerical quantityinterfaceOutput function, can outputdigital signalConveniently connect with accounting machines or field buses.

Pressure transmitters are commonly used to monitor tank levels in various industries. The insufficient accuracy of these pressure measurements can lead to equipment damage, process changes, and other costly consequences, especially when using small tanks and low pressure ranges. There are many different types of liquid level sensors on the market, including floating, ultrasonic, and laser, which can meet the requirements of most applications.
