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.

The HR series dual-core radar level sensor is a non-contact, microprocessor controlled, easy to install and maintain digital level instrument. Through the antenna emitter narrow and low power microwave pulse signals, the pulse signal in the space at the speed of light transmission, encounter reflects measured medium, reflected signal is received, the pulse signal of the transmitted pulse signal and receiving time interval and the datum is proportional to the distance to the surface of the measured medium, the emitting and receiving by measuring the time interval, to realize the antenna to the surface of medium distance measurement.
Built-in LCD display, convenient site setting. It doesn't have to contact industrial media can meet the requirements of most of the material level measurement, so as to thoroughly solve the disadvantages of pressure type, capacitance type, float type of traditional measurement methods such as winding, jam, leaking, corrosion medium, safeguard inconvenience. Thus can be widely used in plastics, coal, grain, sewage disposal, petroleum, chemical, food and beverage, pharmaceutical and other industries. Non-contact measurement, corrosion resistance, easy installation, high measuring accuracy, fast response, long life, good stability, large span, can be used to measure the height of liquid and solid material, in the barn, oil tank, chemical raw materials tank, sewage pool, high corrosive environment, requirements of hygiene, environment of material level measurement is widely used.
