DUOYI DY26A Ultrasonic Leak Location Determine Meter
Dear friends, the following is the difference between DY26 and DY26A
DY26 is suitable for testing leaks in confined spaces.
Instructions:
1. Put the transmitter DY26-T into a closed container to be tested.
2. Adjust the sensitivity of the receiver's DY26-R (you can adjust the sensitivity to the maximum at the beginning), and then hold the receiver DY26-R to slowly move along the measured object and listen to the sound from the headphones.
3. The closer to the point of the leak, the louder the headphones. (At this time you can adjust the sensitivity appropriately)
DY26A is suitable for various leaks and has a 420mm probe.
Instructions:
1. Adjust the sensitivity of DY26A, hold DY26A slowly moving around the measured object,
2. The closer to the point of the leak, the louder the sound from the headphones.
If you are still not sure which one is better, you can consult the seller. Leave me a message. I will reply you as soon as possible.
DY26A is designed to locate leaks in pressure and vacuum system.
It can be used to detect and locate the source of the ultrasonic emission generated by gas or liquid f1owing through a small restrictive opening.
lt uses the advanced ultrasonic sensing technique and features small size, light weight;reliable detection, easy use and utility.
Features:
1. Sense pressurized leaks, detects electrical arcing, and finds falling solenoids, valves and bearings .
2. Comes with a transmitter that emits an ultrasonic frequency to help locate leaaks that are not pressurized. Enough to emit frequencies the detector can pick up.(Only DY26)
3. Detects any pressurized leaking gas, including chlorofluoro carbon(CFCs), hydrofluoro carbon(HFCs), nitrogen(Ni), carbon dioxide(CO2) and steam.
Specification:
Alarm Indication: The"LEAK" LED lights and the"ticking tone" increases in frequency.
Frequency Response: 40kHz ± 2kHz
Operating Condition: temperature:0°C - 40°C
Relative humidity: <80%
Battery: 9V, 6F22 or equivalent
Size: 171*43*38mm
Weight: about 240g
Note :
1.There are many factors involved in the ultrasonic leak detection, such as the pressure within the vessel under test, hole shape, hole size, temperature etc. In some cases, the ultrasonic sound caused by leak is very weak, so you should set the DY26A's sensitivity to the highest level at the beginning of leak detection.
2.If the detected ultrasonic sound is too intense so that it is impossible to pinpoint the leak because the" ticking tone" is too high in frequency, you should decrease the sensitivity with the sensitivity knob.
3.In noisy environments, you can decrease the sensitivity appropriately to exclude the disturbance caused bynoise.
4.When DY26A detects ultrasonic sound, move its probe around the suspected leak to determine whether the detected ultrasonic sound is from the suspected leak or from other areas.
5.Because ultrasonic sound attenuates rapidly when it travels over distance, move the probe of DY26A as close as possible to the suspected leak, remember to decrease the sensitivity if necessary. During location, move the probe slowly.
注意 ：
1.超声波泄漏检测涉及多个因素，如被测容器内的压力，
孔形，孔尺寸，温度等。在某些情况下，泄漏引起的超声波很弱，
所以你应该在泄漏检测开始时将DY26A的灵敏度设置为最高水平。
2.如果检测到的超声波声音过强，则无法确定泄漏点，因为“滴答声”
如果频率太高，则应使用灵敏度旋钮降低灵敏度。
3.在嘈杂的环境中，您可以适当降低灵敏度，以排除噪音引起的干扰。
4.当DY26A检测到超声波时，将其探头移动到可疑泄漏处以确定
检测到的超声波是来自疑似泄漏还是来自其他区域。
5.由于超声波在距离较远时会迅速衰减，请移动DY26A的探头
尽可能接近可疑泄漏，请记住在必要时降低灵敏度。
在定位过程中，缓慢移动探头。
