OMS oil mixed water transmitter
Product Brief
In the oil leakage tank, oil return tank and oil tank with oil-water heat exchange of hydropower station, thermal power plant and large pump station oil system, if mixed with water, it will cause many hazards, the main hazards are: ① water reacts with oil to form acid , Colloid and sludge. ② Reduce lubricity and accelerate the wear of high-stress components. ③Cavitating damage to the control valve or other low-pressure parts; ④Corrosion and corrosion of metal. Therefore, it is necessary to strengthen the monitoring of oil mixed water , so that users can detect and treat the oil in time to ensure the normal operation of the unit and system.
是采用专用电路设计出来的一款性能极高的油混水检测装置。 OMS oil mixed water transmitter is a high performance oil mixed water detection device designed by special circuit. 油混水变送器 。 It has two independent alarm points. The two alarm points are continuously adjustable, and the alarm mode can be set according to the needs on site. It can also provide 4-20mA output or 1-5V output according to needs . Oil mixed water transmitter . 可广泛应用于石油、化工、电力、水处理、冶金、造纸、船舶和锅炉等各行各业的油混水测量。 OMS oil mixed water transmitter can be widely used in oil, water, chemical, electric power, water treatment, metallurgy, paper making, shipbuilding, boiler and other industries to measure oil mixed water.
working principle
传感器是一个圆柱型电容,圆柱型电容器的公式是: The sensor of the OMS oil mixed water transmitter is a cylindrical capacitor. The formula of the cylindrical capacitor is:
,                                     
10 –12 (真空介电常数), Among them, e 0 = 8,854 × 10 –12 (vacuum dielectric constant),
e r = the dielectric constant of the medium between the two poles,
L = height of cylinder;
R 1 = the outer diameter of the inner electrode;
R 2 = the inner diameter of the outer electrode.
For each specific product, except for e r (dielectric constant of the medium between the two poles)       All other parameters have been fixed.
的电路部分通过测量电容值就可以推算出液体的含水量。 Under normal circumstances, the measured medium is pure oil, that is to say, the water content is 0%, then er = ε (oil) is a fixed value, when the oil contains water, because the dielectric constant of water is much greater than For large oils, er = ε (oil mixed water) will change at this time, that is to say, if the water content in the liquid in the cylindrical capacitive sensor changes, the dielectric constant will change, so will the capacitance of the sensor. After the change, the capacitance value changes with the water content. The circuit part of the OMS oil mixed water transmitter can calculate the water content of the liquid by measuring the capacitance value. 输出报警接点信号。 When the water content in the oil reaches the set value, the OMS oil mixed water transmitter outputs an alarm contact signal. The advantage of this cylindrical capacitive sensor is to solve the electromagnetic field shielding problem, the measured results are accurate, high accuracy, low temperature drift, and is not affected by the outside world.
