N2020-04 Ultrasonic Single Channel External Adhesive Liquid Level Switch Introduction: External mounted liquid level switch is a new type of liquid level monitoring and alarm device, mainly used to monitor the liquid level of storage tanks, achieve upper and lower limit alarms, or monitor whether there is medium present in pipelines (dry state protection). This device is particularly suitable for liquid level process control in industries such as pharmaceuticals, petroleum, chemical, power, and food. External mounted liquid level switches are divided into ultrasonic and acoustic waves, among which the external mounted ultrasonic liquid level switch detects the liquid level through high-frequency ultrasonic pulses generated by its sensor (probe). Ultrasonic external mounted liquid level switch is a measurement method that uses ultrasonic radiation, with one sensor emitting and the other sensor receiving; Determine the presence of liquid between two sensors based on the strength of the received ultrasonic signal; Relay output and LED warning can be configured as single channel or dual channel liquid level switches, with fast response speed and high accuracy. characteristic: 1. Non contact measurement: The sensor (probe) of the external mounted ultrasonic level switch is installed on the outer wall of the measured container, without direct contact with the medium, achieving non-contact measurement and avoiding the drawbacks of traditional level switches that require openings on the container wall and hot work. 2. High measurement accuracy: The externally attached ultrasonic level switch can accurately determine whether there is liquid in the container at the monitoring point by detecting the reflection characteristics of ultrasonic pulses on the container wall and liquid. The measurement accuracy can reach 2mm. 3. Wide applicability: External mounted ultrasonic level switches can be applied to containers made of various hard materials such as metals and non metals. The thickness of the tank wall through which the emitted signal can penetrate can reach 70mm, and are suitable for metal tanks with a thickness of about 4mm ranging from Φ 500mm to Φ 1200mm in this example. Technical parameters: Power supply: 10.8V~13.2V or 21.6V~26.4V Display: LED alarm (red light) Output: Relay Convenient configuration of single liquid level and dual liquid level Separate installation, with the probe and control box installed separately. Protection level: IP65
