It can be divided into two types: input type and side mounted type CBM-2100 CBM-2700 static pressure level gauge (static pressure level gauge/level transmitter/level sensor/water level sensor) is a pressure sensor for measuring liquid level. The static pressure level gauge (level gauge) is based on the principle that the measured liquid static pressure is proportional to the height of the liquid. It uses advanced isolation type diffusion silicon sensitive elements or ceramic capacitive pressure sensitive sensors from abroad to convert static pressure into electrical signals, which are then temperature compensated and linearly corrected to convert into standard electrical signals (generally 4-20mA/1-5VDC). The CBM-2100 CBM-2700 series static pressure level gauge (level gauge) is suitable for measuring the level of various media in systems and industries such as petrochemicals, metallurgy, power, pharmaceuticals, water supply and drainage, and environmental protection. The exquisite structure, simple calibration, and flexible installation method provide convenience for users to easily use. Standard signal output modes such as 4-20mA, 0-5V, 0-10mA, etc. can be selected by users according to their needs. working principle: When the liquid level transmitter is inserted into a certain depth of the measured liquid, the pressure formula on the sensor facing the liquid level is: Ρ=ρ. g.H+Po In the formula: P: Pressure on the liquid surface of the transmitter ρ: measured liquid density g: Local gravity acceleration Po: Atmospheric pressure on the liquid surface H: Depth of liquid input into the transmitter At the same time, the pressure of the liquid is introduced into the positive pressure chamber of the sensor through gas guiding stainless steel, and the atmospheric pressure Po on the liquid surface is connected to the negative pressure chamber of the sensor to offset the Po on the back of the sensor, so that the pressure measured by the sensor is: ρ g. H. Obviously, by measuring the pressure P, the depth of the liquid level can be obtained. Good stability, with long-term stability of up to 0.1% FS/year at full and zero positions. Within the compensation temperature range of 0-70 ℃, the temperature drift is less than 0.1% FS, and within the entire allowable operating temperature range, it is less than 0.3% FS. ◆ Equipped with reverse protection and current limiting protection circuits, the transmitter will not be damaged if the positive and negative poles are reversed during installation.

Liquid level measurement is actually measuring the difference between the hydrostatic pressure of the liquid on the probe and the actual atmospheric pressure, and then converting this pressure difference into a 4-20mA output signal through a ceramic sensor (attached to a stainless steel film) and electronic components.

Preparation before installation
Please pay attention to the following items to ensure that the instrument can be installed correctly:
① Please reserve sufficient installation space.
② Please avoid installation environments with strong vibrations.
Performance parameter working principle: The magnetostrictive level gauge consists of three parts: the detection rod, the circuit unit, and the float. During measurement, the circuit unit generates a current pulse that propagates downwards along the magnetostrictive line and generates a circular magnetic field. A float is installed outside the detection rod, which moves up and down along the detection rod with the change of liquid level. Due to the presence of a set of permanent magnets inside the float, it simultaneously generates a magnetic field. When the current magnetic field meets the float magnetic field, a "twisted" pulse, also known as a "return" pulse, is generated. Convert the time difference between the "return" pulse and the current pulse into a pulse signal to calculate the actual position of the float and measure the liquid level. The leakage of gasoline into the soil is a more serious problem than the volatilization of gasoline into the air. In developed countries, this is a necessary indicator and also the world's top technology. Jiahe Technology's magnetostrictive level gauge not only measures the liquid level and temperature parameters of oil tanks, but also measures leakage. The leakage accuracy reaches 0.375 liters/hour, which can meet the needs of different users and achieve a high performance price ratio. Main performance: Range: 0~25000mm Accuracy: ± 0.3mm Resolution: 0.1mm Environmental temperature: -25 ℃~70 ℃ Liquid temperature: -25 ℃~150 ℃ Process interface: 3/4 "NPT power supply: DC24V Output signal: 4~20mA, two-wire/four wire system, Temperature measurement: -25 ℃~70 ℃ Temperature error: ± 0.5 ℃ Explosion proof grade: Exia Ⅱ BT4 Communication: RS-485, RS-232, Modbus, Hart and other protocols, can be equipped with CAN bus or according to user requirements. ※ Note: Corresponding management system software that can be configured according to usage requirements can display parameters such as liquid level height, temperature, volume, mass, density, etc. of various media, and can automatically generate reports and print, network distribution, remote monitoring, and other advanced management functions. Application scenarios: Magnetostrictive level gauges are used for industrial measurement and control of liquid levels in various tanks such as petroleum, chemical raw material storage, industrial processes, biochemistry, medicine, food and beverage, tank area management, and underground inventory of gas stations. They are also used for monitoring dam water levels, reservoir water levels, and sewage treatment. Other applications include: 1. Strong reliability: Due to the waveguide principle used in magnetostrictive level gauges, there are no mechanical movable parts, so there is no friction or wear. The entire converter is enclosed in a stainless steel tube, which is non-contact with the measuring medium. The sensor works reliably and has a long service life. 2. High accuracy: Due to the use of waveguide pulses in magnetostrictive liquid level gauges, the measured displacement is determined by measuring the time of the starting and ending pulses during operation. Therefore, the measurement accuracy is high, with a resolution better than 0.01% FS, which is difficult to achieve with other sensors. 3. Good safety: The magnetostrictive level gauge has high explosion-proof performance, intrinsic safety, and safe use, especially suitable for measuring chemical raw materials and flammable liquids. There is no need to open the can lid during measurement to avoid the safety hazards of manual measurement. 4. Magnetostrictive level gauges are easy to install and maintain: Magnetostrictive level gauges are generally installed through existing pipe openings on the top of the tank, and are particularly suitable for the installation of underground and operational storage tanks, without affecting normal production during the installation process. 5. Facilitating system automation work: The secondary instrument of the magnetostrictive level gauge adopts standard output signals, which are easy for the microcomputer to process the signals and achieve networking work, improving the automation level of the entire measurement system.
