I want a broadband energy switch, frequency: 500k-1.2M, step 10kHz, launch angle 1 does not require 2-frequency curve fluctuations at >3DB 3 sending voltage response to 140dB, recommended by a suitable switcher?
AA broadband switch is required, covering 500k-1.2M, which can be achieved with a combination of two broadband switches.
First, with KDYW-600-01E, this 3db bandwidth > 20%, launch 500K-800K The second paragraph was launched with KDYW-1M-01TA, a bandwidth of 20 per cent of 3db, and 800K-1.2Mhz
The ultrasound energy exchange was 0.25 cm in length, and if the line was 10 m long, would it have had a significant impact on the transmission response?
AAn example is the shield line of 4 x 0.3 square mm of the ultrasound fluid gauger. The cable length is extended by 10 meters. Signal decay - 3dB If it was 100mv, After 10 meters, The signal's down to 70mV. If a single cable core is lower than 0.3 square millimetres, Then the decline will increase, and the same 10 meters of cable, the larger the cut-off, the smaller the decline.
Can a canal flow gauge cable make 100 meters?
丁伯苗Ultrasonic Flow Meters / Open Channel Flow Meters2026-10-30
AThe current cavity of 100 KHz can only be measured by a 30-metre cable; If you want to do 100 meters, you may need to use 64 KHz, or 49 KHz frequency, and we have not tried 100 meters at this time because the signal is going to decay, and if you put a tube 100 meters on the ground, there will actually be a lot of electromagnetic interference coming in, causing ultrasound signals to be largely submerged, so no 100 meters is recommended. Clients are advised to select RS485 output, the flow meter mainframe is installed at the measurement site and the data is received in separate offices.
What's the difference between the noise monitors and the water hearing? How do we decide which product to choose?
丁伯苗Marine Equipment / Hydrophones2026-10-30
AThe noise monitoring instrument product only determines the probability of leakage of a pipe, such as 80 per cent of the probability of leakage, and its measurement is based on the principle of vibration, the technical parameter is thorium 1500 V/g and transmits data only once a day, and batteries are only 19AH, batteries have a five-year life span, built-in gyroscopes, etc. The hydrophones, which are HF-collected, require GPS locator capability, the product collects data for a period of time per day at HF, analyzes the approximate location of the pipe leak through software, and captures the noise of the pipe leak. The two products differ considerably, and the collection rate and the results of the analysis are very different.
Is the transmission voltage response of the ultrasound exchanger the same as the launch sound source level?
陈汀燕Ultrasonic Transducers / Ultrasonic Level Meter Transducers2026-10-30
ANot the same. While both are used to describe the launch performance of power exchangers, their definition, unit and physical significance differ substantially.
Core differences Sending voltage response is a conversion efficiency indicator measured as "the input unit voltage capable of generating more loud pressure at a distance". It normalizes the acoustic conversion capacity of the power exchanger itself, independently of the size of the specific voltage imposed.
The launch acoustic grade is an absolute acoustic volume, describing the actual radiation of the energy exchanger to the level of the acoustic pressure in the water (converted to 1 m) under certain conditions. It depends on the power exchanger's own response, and on the amount of telecommunications you add to it.
Specific comparisons
Sending voltage Response
Definition: The volume of the acoustic pressure and distance at a point in a distant field (usually in the direction of the acoustic axis) divided by the voltage at the input end of the energy exchanger.
Unit: Pa.m/V, usually expressed as dB re 1 μPa/V @ 1m.
Nature: Inherent parameters of the power exchanger, describing the conversion efficiency of the electrosound, not related to the size of the drive.
Launch Acoustic Level
Definition: Acoustic pressure level in the direction of the acoustic axis, 1 m away from the acoustic centre of the energy exchanger.
Unit: Deutsche, base value dB re 1 μPa @ 1 m.
Nature: The results of the actual work vary with the input voltage (or power).
Relationship between the two In numerical terms, they are linked by input voltage. For a given energy switch, at a specified frequency:
Launch acoustic level <unk> Send voltage response + 20log10 (input voltage)
This means that the sending voltage response is a "slash rate" and the sound source level is a "result". The same energy exchanger, you increase the drive, the acoustic level rises, but the transmission of the voltage response (within the rated linear range) remains essentially the same.
I see the surface of the energy exchanger is rough, so can you make it smoother by grinding it manually?
邹威Ultrasonic Transducers / Microtube Flow Meter Transducers2026-10-30
AThis machine looks rough because of the color difference. You can feel the surface. It's actually smooth. And if we do it manually, it's not as smooth as when we're doing it.
My sink is gonna be a little acidic, but it's not strong. Can you use your M33 for the underwater access switch?
AIf water is acidic and corrosive, it's not good for long-term use, because its shell is aluminium. It's more corrosive with ABS shell M36, ABS. If there could be a collision, the stainless steel shell M36 would be more appropriate.
How many blind areas are the four beam sensors?
吴顺南Custom Products / Custom Sensors2026-10-30
AThis depends on the matching power exchange. The blind zone, currently used at 750K, is 15 cm.
Your accuracy is 0.5%, so is the accuracy of the measured range on the tag or the actual scale.
ADo the nesting boat. I'm not sure if I'm going to be able to do this.

The detection of medical bubble custom energy replacements requires, among other things, that clients be asked about the frequency of customization. The client already knows the size of the teacher. What parameters do we have to ask?
韩文娟Custom Products / Custom Transducers2026-10-30
A1. The complete air-jet-replacement structure chart requires each other to give it.
2. Energy exchanger frequency points 3. 3dB bandwidth is <unk>5% 4. Whether the working temperature range is 0-50°C 5. Is the work pressure range constant?
6. How many millimeters does it take to get out?
How long can the power be provided from 3 knots of 18,650 lithium batteries (an individual of 2,500 mAh) using the M80 underwater bathymetry device?
AIn order to simplify the calculation process, Assumptions: Using a lithium cell of 18650, 3 knots (one section 2500 mAh), the voltage is 12.0 V.
1. Equivalence of equipment For the M80 underwater ranger, I've been working 24 hours a day. The average working time is 12V 20mA.
Maximum working hours that batteries theoretically support If we run out of batteries, we'll have to go to the hospital. After 3 knots, the capacity of 3 knots is consistent with the capacity of the single-cell. 2500ma = 2500mA, 2500 mA <unk> 20mA = 125 hours.
And that's the theory of what we're talking about. Using 18650 lithium batteries, The three sections are linked (one section is 2500 mAh) and the other are not the same. I'm not sure what I'm saying. M80 can work 125 hours in succession.
Wind speed is 80 degrees below temperature. What's the probe?
AThe normal wind speed machine, the probe and the circuit board, is to heat up, and now the wind speeder panel has two 200 KHZ ultrasound exchangers. To pvdf material, heat is to be made on the existing ore ultrasound speeds, which means heat on circuit boards and on probes.
Can we use a panel-drive power exchange to achieve a reception sensitivity of 1.351 mV/Pa? Can you do that?
林永海Ultrasonic Transducers / Ultrasonic Development Boards2026-10-30
AYou can try to change the circuits, match the power exchange.

And you're talking about aggregates at this high mud, for close-range measurements.
KDYW-88K-200B Frequency: 88 KHz+5%;
Sensitivity: Put the energy exchanger in the pool and impregnate over the water circuit to carry the voltage: 500 Vpp, with a reflection panel at a distance of 0.7 m, to launch itself for reception, without the original echo range of 5.0 V being processed by the circuit.
We want to make a power exchanger whose parameters require 750k, with a bandwidth of more than 20% and an angle of 0.55° *60° = = 10.83 cm*2mm;
AAqueous energy exchangers, 750 KHz, ceramic tablets with an angle of 10.83 cm length that does not reach 0.55 degrees, and a angle of 0.55 degrees, with a length of ceramic tablets required to be 220 mm.
