Non-contact Ultrasonic Level Sensors For Continuous Level Measurement
1. Application:
The series is an integrated two-wire ultrasonic level meter continuous contactless liquid level measurement of liquids and solids. It consists of probes and electronic devices, both of which are leak-proof structure. This series of products can be widely used in metallurgical industry,
chemical, electricity.
2. Characteristics
1) Compact continuous non-contact liquid level measurement;
2) Body design, easy installation;
3) Over-voltage, over-current protection, lightning protection;
4) LCD or LED large display window, easy to debug and observe;
5) Anti-interference ability;
6) 4-20mA output;
7) Intelligent signal processing technology to ensure that the instrument meets all kinds of workplace
8) All metal case (IP67), sealed, alkali resistant, meet harsh environment.
3. Measuring principle
Ultrasonic Level Sensor with Indicator emits ultrasonic pulses transmitted through the transmission medium to the measured body surface, the reflection and then return through the medium of sound propagation to the receiver transducer to measure the ultrasonic pulse from transmitter to receiver propagation in the medium of sound propagation time. Sound transmission medium according to the speed of sound, can be called from the transducer distance to the object plane to determine the material level.
4. Technical data:
Basic data
| Type | MLT |
| Power supply | DC24V (±10%) 60mA |
| Display | 4 digit LCD |
| Accuracy | 0.2% of full span (in air) |
| Output current | 4-20mA |
| Output load | 0-500Ω |
| Temperature range | -40℃~80℃ |
| Pressure range | ±0.1MP (press definitely) |
| Measure cycle | 1 second (changeable ) |
| Beam angle | 8º(3db) for range :4m 6m 8m 5º(3db) for range :12m 15m 20m 30m |
| Parameter set up | 3 induction buttons |
| Cable connection | PG13.5 |
| Material | The electronic unit : metal The sensor: ABS |
| Protect grade | IP67 |
| Fix | Screw or Flange |
The measuring range:
| MODEL | MLT4 | MLT6 | MLT8 | MLT12 | MLT15 | MLT20 | MLT30 |
| LIQUID | 4.00m | 6.00m | 8.00m | 12.00m | 15.00m | 20.00m | 30.00m |
| SOLID | 3.00m | 5.00m | 7.00m | 10.00m | 15.00 |
Note: When using to measuring solid level, the most energy of ultrasonic is absorbed or scattered by solid level, so the back wave is very little, the valid measuring range of solid level is about 50% of liquid level. And the valid measuring range of solid level is determined by the installing location and rang.
| MODEL | MLT4 | MLT6 | MLT8 | MLT12 | MLT15 | MLT20 | MLT30 |
| Blacking distance | 0.20m | 0.25m | 0.30m | 0.45m | 0.60m | 0.80m | 1.20m |
