The explanation is mainly to clearly analyze the liquid level transmitter and the input level gauge, and compare and analyze the two.
Liquid level transmitter: It is the extension and development of pressure transmitter technology. According to the principle that the pressure of liquid of different specific gravity is different at different heights, the volume and liquid height of water, oil and paste are realized. Accurate measurement and transmission of weight.
Advantages of the level transmitter:
1. Easy to install, easy to use, and interchangeable.
2. It is suitable for the measurement of the liquid level and interface of the liquid medium in the container. In addition to on-site instructions, it can also be equipped with remote transmitters, alarm switches and detection functions.
3. The indication is novel, the reading is intuitive, the eye-catching, and the direction of the observation indicator can be changed according to the user's needs.
4, the measurement range is large, not limited by the height of the storage tank.
5. The indicating mechanism is completely isolated from the measured medium, with good sealing performance, high reliability and safe use.
7. High-quality sensing has high sensitivity and fast response, accurately reflecting subtle changes in flow or static liquid level, and high measurement accuracy.
8, with intrinsic safety explosion-proof and isolation and explosion-proof capabilities, can be applied to a variety of hazardous locations.
9, the anti-blocking design can achieve the measurement of the level of the paste medium.
10, 100% aliquot scale, LED, LCD three indicator head, on-site reading is very convenient.
11, 4-20mA DC two-wire system signal transmission, strong anti-interference ability, long transmission distance.
12, fine and unique zero point, full range, non-linear compensation, to ensure the accuracy of the instrument within the scope of use conditions, long-term stability.
13. The pressure sensor directly senses the liquid level pressure and is not affected by the foaming and deposition of the medium.
14. It can be used to measure oil, water and paste compatible with 316 stainless steel. It has certain anti-corrosion ability.
In contrast, the input level gauge: the input level gauge (input level transmitter) is based on the principle that the measured hydrostatic pressure is proportional to the height of the liquid, using the piezoresistive effect of diffused silicon or ceramic sensitive components. , the static pressure is converted into an electrical signal. Temperature compensated and linearly corrected. Converted to 4-20mADC standard current signal output. The sensor part of the input level transmitter can be directly put into the liquid, and the transmitter part can be fixed by flange or bracket, which is very convenient for installation and use.
Input level gauge features
1, good stability, high precision
2. The input type liquid level transmitter is directly put into the measured medium, and the installation and use are quite convenient.
3, solid structure, no moving Parts , high reliability, long service life from water, oil to a viscosity of the paste can be measured with high precision, not affected by the measured medium foaming, deposition, electrical characteristics Range of temperature compensation. The input level transmitter has reverse polarity protection and overload current limit protection.
4, input type, straight rod type, flange type, thread type, inductive type, screw type, float type structure design, equipped with anti-blocking design, easy to install, easy to use, strong interchangeability, high quality sensor The sensitivity is high, the response speed is fast, and it accurately reflects the subtle changes of the flow or static liquid level, and the measurement accuracy is high.
