What are the performance characteristics of ultrasonic liquid level sensors?
Ultrasonic level gauges can adopt two-wire, three wire, or four wire technology. The two-wire system is: power supply and signal output are shared; The three wire system is: the power supply circuit and the signal output circuit are independent. When using DC 24V power supply, a 3-core cable can be used, and the negative end of the power supply and the negative end of the signal output share the same core wire; When using AC 220V power supply or DC 24V power supply and requiring complete isolation between the power supply circuit and the signal output circuit, a 4-core cable should be used. DC or AC power supply, with 4-20mADC and high/low switch output. The range of the split type ultrasonic level gauge is 0-50 meters, with multiple forms to choose from, suitable for various corrosive and chemical applications, high accuracy, remote signal output, and PLC system monitoring. The working principle of the ultrasonic liquid level meter in English is that the ultrasonic transducer (probe) emits high-frequency pulse sound waves, which are reflected back on the surface of the measured material and converted into electrical signals by the transducer The propagation time of sound waves is directly proportional to the distance they travel to the surface of an object The relationship between the distance S of sound wave transmission, the speed C of the sound sail, and the time T of sound wave transmission can be expressed by the formula: S=C × T/2. The probe part emits ultrasonic waves, which are then reflected by the liquid surface and received by the probe part. The distance from the probe to the liquid (object) surface is proportional to th
2. How is the pressure unit mlc converted to international standard units?
mlc is the abbreviation for meter liquid column, which means meter liquid column. 1 mlc=0.01Mpa1 standard atmospheric pressure=760mm mercury column=76cm mercury column=1.01325 × 10 ^ 5Pa=10.336m water column. 1 standard atmospheric pressure pants with a torque of 101325 N/㎡. (In calculations, it is usually 1 standard atmospheric pressure=1.01 × 10 ^ 5) To make accurate calculations, the relationship is as follows: Pressure conversion relationship: 1 dyn/cm2=0.1 Pa, 1 Torr=133.322 Pa, 1 mmHg=133.322 Pa, 1 mmHg=9.80665 Pa, 1 engineering atmospheric pressure=98.0665 kPa, 1 kPa=0.145 pounds force per square inch (psi)=0.0102 kilograms force per square centimeter (kgf/cm2)=0.0098 atmospheres (atm), 1 pound force per square inch (psi))=6.895 kilopascals (kPa)=0.0703 kilogram force per square centimeter (kg/cm2)=0.0689 bar=0.068 atmospheres (atm) 1 physical atmosphere (atm)=101.325 kilopascals (kPa)=14.6400392 pounds per square inch (psi)=1.01325 bar
3. Translate the experimental principle of the plate hole flowmeter into English
Orifice Meter is also known as differential pressure flowmeter is determined by a test piece (cutting pieces) and the second device (differential pressure transmitter and flow indicator), is widely used in gas, steam and liquid flow measurements. It has the characteristics of simple structure, easy maintenance, stable performance, and reliable use. Has a simple structure, easy maintenance, stable performance, reliable and so on.
