LLE Series Liquid Level Sensors Description
The enhanced series of liquid level sensors incorporates a photo-transistor trigger which provides a digital output that denotes the presence or absence of liquid.

The mode of operation is derived from the principle of total internal reflection. An LED and photo-transistor are housed within a plastic dome at the head of the device. When no liquid is present, light from the LED is internally reflected from the dome to the photo-transistor. When liquid covers the dome, the effective refractive index at the dome-liquid boundary changes, allowing some light from the LED to escape. Thus the amount of light received by the photo- transistor is reduced and the output switches, indicating the presence of liquid. This method of liquid level sensing is very fast, and almost instantaneous for water.

Agecho ultrasonic sensors salient features:
Agecho ultrasonic sensors are available with output options such as analog current 4-20ma, analogue voltage 0-5v, on/off signal, trigger output for multi-sensor application, pulse width , serial ttl , serial rs 232c.
Agecho is very useful non-contact type of sensing or presence or counting of object. On/off type signal is also available.
Agecho sensing range: 200mm to 1000mm … up to … 6000mm. (19.7feet) (0-200mm is dead band).
Agecho accuracy is 1% of the full scale.
Agecho operating voltage 12v dc, with reverse polarity protection.(24v dc optional)
Agecho is self-calibrated. Microcontroller is present in each sensor. This provides direct distance/depth reading with better calibration and communication with the controller module.
Agecho is very easy to install, rugged design for use in dusty and humid conditions, suitable for outdoor as well as indoor use.
Agecho very useful for non-contact distance/level measurement. The distance of the target is measured, not just its presence, but gives directly 4-20ma, serial or pulse width data proportional to the distance of the target.
Agecho operating temperature 0 to 65 degree celsius.
Agecho temperature compensated measurement for better accuracy (optional).
Agecho unaffected by ambient light, object color or any other optical characteristic. Works with hard materials like metal sheet, plywood, or soft materials like cloth and paper, rubber etc.

FS-IR02B series Water Liquid Single Point Level Sensor, the theory is infrared, it can totally replace traditional float level switch, it controls the level though output high or low voltage. When the detected level is in air, due to reflect of the prism,most of light will enter receiver LED, optical level sensor will output high voltage. When the detected level is in water, due to refraction of the liquid, just less of light enter receiver LED, optical level sensor will output low voltage.

The FS-IR2003D is a single point liquid level switch that can operate in high pressure, high temperature, and aggressive
environments due to its stainless steel and glass construction. This level switch offers industrial supply voltages and outputs that can directly drive loads. This model has a wide operating voltage, which is from 5VDC to 24VDC. The output ways have two types, NPN and PNP. The sensor can detect the presence or absence of almost any liquid, and can be configured to output a high or low signal in either a wet or dry state.

The microcontroller based Stainless Glass Range liquid level switches are solid state, incorporating an infra-red LED and
phototransistor which are optically coupled by the tip when the sensor is in air. When the sensing tip is immersed in liquid, the infrared light escapes making the output change state. The sensor can detect the presence or absence of almost any liquid type; oil or water based. It is insensitive to ambient light and is not affected by foam when in air or by small bubbles when in liquid.
