Level Transmitter Level Sensor Controller Input Water Level Sensor 4-20MA

Description: Main application areas of the product Low liquid level monitoring of open liquid tanks, depth or level measurement of wells or open waters, groundwater level measurement, sewage treatment, water supply, chemical and pharmaceutical industries, constant pressure water supply systems and other industries liquid level measurement and control. 2: Main technical parameters Accuracy level: 5% Power supply range: 12～36VDC Output signal: 4～20mA Probe material: stainless steel Medium temperature: -30～60℃ Environment temperature: -40～85℃ 3: Principle of static pressure measurement When the sensor is thrown into a certain depth in the measured liquid, the formula for the pressure on the liquid surface of the sensor is: Ρ=ρ.g.H + Po Where: P: Pressure on the liquid level of the level gauge ρ: Density of the measured liquid g: acceleration of gravity (according to 9.8015 during debugging) Po: atmospheric pressure on the liquid surface H: The depth of the sensor into the liquid At the same time, the pressure of the liquid is introduced into the positive pressure cavity of the sensor through the gas-conducting stainless steel, and then the atmospheric pressure Po on the liquid surface is connected to the negative pressure cavity of the sensor to offset the Po on the back of the sensor, so that the pressure measured by the sensor is: ρ. gH, obviously, the liquid level depth can be obtained by measuring the pressure P. The input type liquid level transmitter adopts a high-performance diffused silicon piezoresistive pressure sensor as the measuring element. After a high-reliability amplifying processing circuit and precise temperature compensation, the gauge pressure or absolute pressure of the measured medium is converted into a standard voltage. Or current signal. This product is small in size and easy to use and install. It can measure the height of the liquid level from the end of the transmitter to the liquid surface directly by putting it in the water 5: Product features Adopt advanced circuit processing technology, stable performance and high sensitivity; multiple ranges, maximum measurable 200m (water column pressure); use 316L stainless steel isolation diaphragm, suitable for multiple measurement media; flexible configuration, different configurations can be selected according to needs; Type and split type are optional; reverse polarity and overvoltage protection; anti-shock and lightning protection design; laser resistance temperature compensation, zero point and range can be adjusted on site; wide range of corrosion resistance, suitable for a variety of media; overload and resistance Strong interference ability and stable performance.
