It is generally suitable for short distance measurement. If it is  industrial ultrasonic proximity switch, some brands can measure 8 meters and 10 meters. At present, our max ranging distance is 6m. In addition, our short range proximity switch can detect 20 to 150mm. However, ultrasonic waves can also measure very long distances. For example, portable ultrasonic depth sounder can detect 300 metres. This is mainly applicable for lake and ocean depth detection.  If it is an ultrasonic level meter, it can also detect up to 60m or 70m.

The detection distance of an ultrasonic sensor depends on many  factors. These include wavelength and frequency. In general, the longer the wavelength and the smaller the frequency, the greater the detection distance. For example, some 20khz ultrasonic transmitters can measure 15 meters. The 40KHz transmitter can generally detect 12m or 6m. And 58KHz sensor can generally measure 5m. They are generally used in car reversing radar. 100Khz transducer can detect 3m~4m. And 200KHz transducer can detect 2m. But 1MHz ultrasonic transducer only can detect 1m.

At present, the frequency range of our ultrasonic transducers is from 14 KHz to 4 MHz. The low frequency transducers are mainly used for distance or level measurement. Ultra-high frequency transducers are mainly suitable for flow measurement, e.g. 1MHz, 3MHz and 4MHz.

Currently, our transducers are able to withstand 10MPa and 160℃. The usual housings are stainless steel or titanium alloy.

It usually takes 30~40 days. Firstly, design the transducer structure. Then purchase the raw materials, such as piezoelectric ceramics, wires, copper sheets, and metal casings, etc. Afterwards, we will verify the product solution and sample production.

Sample production generally includes SMD, assembly, sealing and testing.

For piezo ceramic materials with prices, they are in stock. If you need to customize sizes, it will take about 25 days.

And for industrial ultrasonic sensors with prices, they are in stock. If not, it will need about 10 days.

For ultrasonic transmitter and receiver with prices, they are in stock. If not,  it will cost about 15 days.

You can check the price on our website. Of course, please note that the prices are not our wholesale price.

Different kinds of sensors, different prices. They are many cheap cost ultrasonic sensors. For example, the open type transmitter and receiver can be as low as $0.3/pc for wholesale. The arduino hc sr04 module also has low cost. If it is waterproof, the price will be a bit higher.

In addition, the industrial ultrasonic sensor price will be much higher. For a 2000mm sensor, the cost is at least USD115 in retail. If you choose other brands like Microsonic, Banner, Pepperl+Fuchs, it will be much more expensive. Their costs are at least twice as much as ours.

In fact, this not even the most expensive. Some ultrasonic transducers for flow meters have very expensive price. They are even as high as thousands of dollars.

Therefore, different applications, different prices. Different processing difficulty, different costs.

Sure. The prices on the website is only for small quantity. More quantities, more discounts. Welcome to contact us by Email or Whatsapp. We will provides the wholesale price for ultrasonic sensor and piezo ceramic products.

Ultrasound sensor has a wide range of applications. It can detect transparent or coloured objects, metallic or non-metallic objects, solids, liquids and powders. It is also particularly suitable for poorly lit and dusty environments.

However, it is not suitable for volatile materials. Because they will affect the measurement accuracy of the sensor. We also do not recommend using it to measure small objects, such as wires and ropes. This is because they do not reflect enough sound waves back. It is also not suitable for breathable materials. For example, we don’t use ultrasonic slot sensors to measure fabrics and non-wovens. In addition, if the item is able to absorb the ultrasonic waves, then it will affect the detection effect. Therefore, it cannot detect sponges, cotton either.

The protection level of our industrial ultrasonic proximity switch is IP65 and IP67. In addition, the open type transmitter and receiver is IP65. And enclose type ultrasonic transceiver is IP68. They are waterproof. Besides, we also have the IP68 class ultrasonic range finder module. Usually use it for underwater robots.

The blind zone is relative to the measuring distance of the ultrasound. Generally, if the range is small, the blind zone is small. If the measuring range is large, the blind zone is large.

Our 150mm proximity sensor has blind zone of 20mm. And 350mm sensor is 30mm. And the blind zone of 1000mm sensor is 60mm. For more information, pls check our catalog.

(1) Our ultrasonic proximity sensor has three kinds of output modes.

① Switching signal: PNP and NPN (n.o. / n.c. /hysteresis mode);

② Analog signal: current (4~20mA), voltage (0~5V, 0~10V);

③ Digital signal: RS485, RS232, TTL232;

(2) The available output of ultrasonic sensor module: UART, PWM pulse width, RS485, IIC, switching output, TTL level output;

Yes. All our industrial ultrasonic proximity switches have temperature compensation.

Temperature has an effect on the speed of sound. Without temperature compensation, this will lead to measurement errors. This is especially true in environments with big temperature variations. So this function will help ensures measurement accuracy.
