Types and characteristics of water level detector
The height of the liquid medium in the container is called the water level, and the meter that measures the liquid level is called the water level detector. The level gauge is a kind of level gauge. The types of level gauges include input type, ultrasonic, maglev type, pressure type, sonar wave, magnetic flap, radar, etc.
The JXBS-3001-Level series transmitter is mainly composed of three parts: imported load cell sensor, measuring circuit and process connection. It can convert the pressure signal parameters felt by the load cell into a standard liquid level signal. When the sensor is dropped into a certain depth in the measured liquid. The force of the measured medium is introduced into the positive pressure cavity of the sensor.
The atmospheric pressure Po on the liquid surface is connected to the negative pressure cavity of the sensor through a cable air duct. To offset the Po on the front of the sensor. Make the sensor measure the pressure. By measuring the pressure, the liquid level depth can be obtained. This product adopts imported diffused silicon pressure detection sensor with stable signal and high precision. Anti-interference, low temperature drift and high stability. It has high measurement accuracy. It is an ideal liquid level measuring instrument in the field of industrial automation.
Ultrasonic level gauge sensor
Ultrasonic level gauge sensor is a sensor based on 4G mobile network for data transmission. No special communication lines are required. Relying on the ubiquitous mobile phone signal network can realize the Internet of Things detection. The 4G sensor uses a stable and reliable operator network. It has mature technology and stable transmission. Features such as strong signal and wide coverage. At the same time, the device supports timing data collection and active upload to the server platform. Ultrasonic level gauge is a distance measuring instrument developed based on ultrasonic principles.
Use the sent sound pulses. Measure the time at the receiving end to calculate the distance. The shell of the whole machine is made of ABS material. It has light weight and no moving parts. Rugged and durable features. And there is no need for maintenance and on-site calibration. It can be used in conjunction with a computer, data collector or other collection equipment that conforms to RS485. This product has no moving parts, low wear and long service life. Engineering plastic shell, lightweight design, portable, easy to install and disassemble. No maintenance and on-site calibration are required. Imported detection chip is adopted, which has fast response speed; the zero drift is small and the repeatability is good. The product has been tested by EMC and EMI and has strong anti-interference ability. The equipment is stable, reliable and accurate in detection. Remote cloud alarm monitoring.
