Intelligent non-contact Level Sensor / detector It adopts advanced signal processing technology and high speed of the signal processing chip, the thickness of the container will be less relevant for the measure level, and the high level of the sealed container, the true non-contact measurement is made. The level sensor (detector) will be mounted on the top / bottom of the outer container (The high level and low level), it will be useless to drill a hole to the non-metal container, the installation is very simple. this measure level sensor sensor is the most ideal for various toxic materials, strong acid, strong alkali and various liquids in high pressure sealed container. There will be no special requirements for the liquid medium and the material vessel, and 'widely used.
Features:
- Non-contact liquid level sensors for non-metallic wall the container without direct contact with the liquid,
- They are not subject to corrosion acids and alkalis and other corrosive liquids, or other debris from the scale effect.
- Intelligent memory function and the level of regulation of the level, Status display level, multi-point serial connection, supports NPN output, high-low output level, PNP output, RS485 output signal
- Detection is accurate and stable, able to detect the level of boiling water
- Pure structure of the electronic circuit, not-mechanical work, duration of life and stable performance.
- High stability, high sensitivity, strong interference capability, free from external electromagnetic interference. There are a special treat for frequency interference common mode noise, compatible with all 5 ~ 24 V Power adapter in the market.
- Strong compatibility, penetrate various non-metallic containers, such as plastic, glass, ceramic and other containers, sensing distance up to more than 10mm, liquid, powder, Particulate can be detected.
- Open collector output, wide voltage range (5 V ~ 12 V or 12 V ~ 24 V), suitable for connecting the various circuits and applications of the product.

Principle of Operation:
Intelligent non-contact level detector detection is the use of capacity in water detect whether the liquid is present, when there 'is liquid access to the detector, c 'it is static due to distributed capacitance capacity exists in the detector,
when the increase in level and close to the detector, the parasitic capacitance of the liquid will couple to this static capacity, capacitance value of the final detector becomes larger, this change in IC input capacitance signal to convert the signal, make the change of capability to convert some of the signal change, and then by a certain algorithm to detect and determine the measure of the amount of change, when the change exceeds a certain threshold level reaches the sensor point.
