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.

Non contact ultrasonic level switch is a kind of non-contact, high reliability, high cost performance, easy installation and maintenance of material level measuring instrument.It doesn't have to contact medium can meet the requirements of most of the material level measurement.Firing pulse and receives the pulse interval and the antenna to the surface of the measured medium is proportional to the distance, to calculate the distance on the surface of the antenna to the measured medium. Ultrasonic Level Sensor, As shown in Picture below, the ultrasonic sensor Tx transmits ultrasonic waves reflected after encountering an obstacle received by the ultrasonic sensor Rx calculates the distance d of the obstacle according to Time-Of-Flight (TOF):d = (C x t)/2

The Separated Liquid Flow Sensor A1MF can be used to detect high and low water levels, etc., and give a signal when the water level reaches a certain position. The Non contact Infrared Level Sensor is a device used to sense the level of liquid in a tank. There is a board in the plastic housing. When the liquid level rises, it drives the prism, level switch will output low voltage signal. When the liquid level falls, infrared level control will output high voltage signal. The photoelectric liquid level switch uses the principle of optical reflection to measure, the performance of level sensor will be affected when it is exposed to direct sunlight or other infrared interference. Adjust the mounting angle or use a hood to avoid it. The photoelectric liquid level switch has high precision, low price, high reliability and wide application environment, it is less affected by strong acid, alkali and viscosity.
