Optional Short Range Ultrasonic Distance Transducer for 0.5m Distance Measurement

Product Description

1.Product Introduction

Detecting non-contact and wear-free object by using an acoustic wave medium. Ultrasonic sensors can detect them ,including transparent and colored objects, metallic or non-metallic objects and solid, liquid or powdered materials. which won't affect the detection performance of the ultrasonic sensor even if it has smoke, dust, or rain .

2.Principle of Ultrasonic Distance Transducer

The ultrasonic pulse emitted by the ultrasonic transducer is transmitted to the measure medium through the propagation medium, and then returned to the receiving transducer through the sound bearing medium, Detecting the transmitting time of ultrasonic pulse from the transmitting to the receiving in the sound bearing medium. According to the speed of sound in the sound bearing medium, the distance from the transducer to the medium surface can be calculated. Thereby determining the liquid level. So we can calculate the distance from the probe to the reflecting surface D = C*t/2 (D is the distance, C is the speed of sound, and t is the time).

5.Installation Dimension:

(1)

(2)

(3)

①Install a flange above the object need to be tested ②Place a gasket with the same inner diameter on the flange

③Distance measuring sensor aligns hole of the flange ④Put the distance sensor in the hole of flange

⑤See from the bottom of the flange ⑥Place a gasket with the same inner diameter on the flange

⑦Fix the distance measuring sensor by Screwing on the nut ⑧Connect up the cable on the ranging sensor

(4) mode of connection:

Power: Red line: 24VDC + ; black line: 24VDC –

1. 4~20mA: Blue line: mA +; yellow line: mA–

2. 0~5V: Blue line: V +; yellow line: V–

3. 485/232 Communication: Yellow line: T/R+ ; Blue line: T/R–

4. Relay signal: blue line, yellow line

5. NPN signal: Blue line: NPN+ ; Yellow line: NPN -

6. PNP signal: Blue line: PNP+ ; Yellow line: PNP-

Remarks:

1. Output signal is selectable one of them (1~6) ;

2. The black wire should be grounded reliably;

3. When the ranging transducer is a mA module, the yellow line (mA-) can also be grounded.

6. Signal Description:

When the power is turned on at first, the power indicator "green light" is always on. When is searching the echo signal, the status indicator "red light" flashes. When is searching the correct echo, the status indicator "red light" remains on. When is measured normally, the Nixie tube displays the actual measurement value; when it is the lost state, the Nixie tube displays "- - -".

7. Serial Assistant to Modify Parameters:

Note: This is only applies to ranging sensors with 485 or 232 communication modules.

Serial port connection:

As shown in Figure A: the serial port is connected to the serial port of the computer, the other end is connected to the RS-232 end of 485 to 232.;

Cable connection:

Figure B: Red line is connected to 24V+; black is connected to 24V-; yellow line is connected to 485 T/R+; blue line is connected to 485T/R-;
