DC24V Ultrasonic Float Level Switch Anti Corrosion 4-20MA 0-15m

Product Specification

           MC Anti-corrosion and explosion-proof ultrasonic level meter 4-20MA

Introduction

Ultrasonic level meter is a monitoring instrument for measuring liquid height, tank height and material position. The instrument itself can adopt two wire system, three wire system or four wire system technology, two wire system: power supply and signal output common; Three-wire system: single X power supply loop and signal output loop, when using DC 24V power supply, can use a 3-core cable, the negative end of the power supply and the negative end of the signal output share a core wire; Four-wire system: when the USE of AC 220v power supply, or when the use of DC 24V power supply, the power supply loop and signal output loop is completely isolated, should use a 4-core cable. Dc or AC power supply, with 4~20mADC, high and low switching output.

Operating principle

Anti-corrosion and explosion-proof ultrasonic level meter is a digital level meter controlled by microprocessor. In the measurement of ultrasonic pulse from the sensor (transducer), the sound wave reflected by the surface of the liquid is received by the same sensor, through the piezoelectric crystal converted into electrical signals, and the time between the transmission and reception of the sound wave to calculate the distance from the sensor to the surface of the liquid to be measured. Due to the use of non-contact measurement, the measured medium is almost unlimited, can be widely used in a variety of liquid and solid material height measurement.

Algorithm optimization, intelligent filtering, high frequency signal, strong penetration, stable measurement

1. Liquid crystal display liquid level value, measurement data at a glance

2. The electrical interface is made of ABS material, resistant to impact and aging

3. Integral seal to prevent dampness from affecting the performance of the whole machine

Intelligent acoustic wave technology can carry out intelligent echo analysis, without any debugging and other special steps, this technology has the function of dynamic thinking, dynamic analysis. The precision of the instrument is greatly improved, the precision of liquid level reaches 0.5%, and it can resist all kinds of interference waves.

Performance characteristic

1. Choose high-quality power module, components choose imported high stability and reliable devices, can completely replace the same type of imported instruments

2. Acoustic wave intelligent technology software can carry out intelligent echo analysis, without any debugging and other special steps, this technology has the function of dynamic thinking and dynamic analysis

3. The liquid level accuracy is 0.25%, which can resist various interference waves

4. Range :0-15 meters, various forms of optional, suitable for all kinds of corrosive, chemical applications, high precision, remote signal output,PLC system monitoring

Construction

                                             Product dimension drawing

Installation method: bracket installation is generally adopted in open environment. Cut a round hole with a diameter of 60mm on the installation position of the tank or tank with the instrument's own flange, put the instrument probe into it, and then screw the flange upward to ensure that the probe surface of the instrument is level with the measured liquid level

B(Blind area): 0.35 m to 0.6 m       D: ullage         L: level

H:Height              F: Distance from the wall(0.3~2m)         L:L-D         

1. The datum level of measurement is the lower edge of the sensor.

2. The upper limit of object level cannot enter the blind area of measurement

3. When measuring the material level, it must avoid the feed opening.

4. It is best to protect against long-term rain when installed outdoors
