- Product Detail
-
- Commodity name: Ultrasonic Air Detector Medical Sensor Liquid Pot Sensor Signal Sensor 5VDC 12VDC 24VDC Measuring 8-12mm Tube
- Commodity ID: 306
typical application:
Hemodialysis machine pipeline bubble detection, blood perfusion machine pipeline bubble detection, other liquid flow pipeline bubble detection
Timely monitoring, etc.
working principle:
According to the different propagation characteristics of ultrasonic waves in different media, through special circuit analysis and processing, to
Intelligently identify the medium condition in the monitored flow pipe.
Product technical features: :
1. High precision, strong anti-interference ability, response time 500μS;
2. The snap-in tube installation does not need to cut off the pipeline, and has no pollution to the detection liquid;
3. Not affected by changes in fluid color and pipe material, it can detect air bubbles in most liquids;
4. Low cost, long life, low power consumption, maximum 45mA, optional 5VDC or 7.5-15VDC power supply;
5. This model is suitable for infusion tubes with an outer diameter of 19 to 23mm, other diameters or rigid pipelines can be customized according to user requirements.
Wide application;
Wiring Instructions:
Red—+5V
Black - 0V
Blue - upper liquid level signal
Yellow - lower liquid level signal
Green - door close signal
Gray - Shield Ground
testing method:
1. Detect the door closing signal: Power on the product, connect the red test lead of the multimeter to the green wire, and the black test lead to 0V, when the door is not closed
The output is a low-level signal, and the output is a high-level signal when the door is completely closed;
2. Upper liquid level detection: connect the red test lead of the multimeter to the blue wire, and insert the consumables filled with half of the liquid into the product detection tank.
Fasten the cover, when the liquid in the consumables fills the upper liquid level detection point, the output will be a high level signal for a while, and the upper liquid level will be detected.
When there is no liquid in the consumables at the detection place, the output is a low level signal;
3. Lower liquid level detection: the red test lead of the multimeter is connected to the yellow wire, and the detection method is the same as that in 2.2
