Non-contact level sensor switch is designed to provide clamp on level measurement for non-metal container and pipe. With our patented technology, the level sensor can detect level inside from external surface of containers. That means it won't contact liquid and don't need to open closed container or cut it. Thus, it doesn't pollute the liquid. The non-metal material can be plastic, glass,ceramics,etc,and typical non-metal containers mainly have tank,pipe,bottle,barrel,drum,etc.

The economic non contact liquid level sensor is developed on advanced signal process technology by high speed signal process chip. It can measure liquid level of closed container by penetrating the wall of container. The liquid level sensor is usually fixed on the vertical side of non-metal container, and doesn't need to cut holes. It is easy to install and don't stop manufacturing. It can still work well even though the containers have various of poisonous materials,strong acid, strong alkali,etc.

With low cost and good performance, the level sensor switch has been widely used in water tower, pipe, water tank, environment protection device, medical device, close-stool, whirlpool tub, coffee maker, water dispenser, etc.

  • Induction surface material: ABS
  • Relative humidity:5%-95%
  • Dimension:16x11x5mm(only sensor without cable)

Non Contact Level Sensor Switch for Solid

Except used for liquid,e.g. water,etc, the level sensor switch can be used for solid level measurement,which mainly includes particles and powder. The following picture is used for bean level monitor.non-contact-level-sensor-switch-solid

 

Non Contact Level/Flow Switch Sensor for Pipe Level

 

   (Non Contact Level Test for Closed Tank by Side Vertical Tube)

This type product is specially designed for non-metal pipe test. It can be used to measure level and flow of pipes.The pipe diameter shouldn't be less than 10mm. Pipe material is non-metal,e.g.plastic,PVC,glass,rubber,acrylic,ceramics(no water absorbent),etc. The non-contact level flow switch is low cost solution. If you require higher performance or for metal pipes,you may select our non-invasive ultrasonic flow meters.

Specification:

  • Level accuracy:+/- 1.5mm;
  • Power supply: 5-24VDC
  • Current consumption: 5mA
  • Response time:50S
  • Environment temp.:0 - 85 Deg.C
  • Max output current: 1-100mA
  • Output way: NPN,PNP,High/Low electric level optional
  • Output voltage(high electric level):InVCC
  • Output voltage(LOW electric level):0V
  • Protection class: IP67
  • Induction surface material: ABS
  • Relative humidity:5%-95%
  • Dimension:28x16.9mm(check the picture below)

Application condition for pipe(liquid):

  • Dynamic viscosity<10mPaS, normal measurement.
  • 10mPaS<Dynamic viscosity<30mPaS, test may be effected.
  • Dynamic viscosity>30mPaS, can't measure.

Note: As the temperature becomes higher, the viscosity is down.Most of high viscosity liquid are easily effected. Please pay attention to temperature changing while measuring viscosity liquid.
