PCE-LDC 15 Ultrasonic Leak Detector 

The sonic funnel transmits this ultrasound to the PCE-LDC 15 Ultrasonic Leak Detector, which then transforms the inaudible ultrasound into audible frequencies. The leak may be accurately targeted thanks to the laser pointer included within the leak detector. The horn of the leak detector is made to be able to take up sound waves, concentrate them so that they behave like a directional microphone, and then muffle extraneous sounds.

PCE-LDC 15 Ultrasonic Leak Detector

The Ultrasonic Leak Detector is an acoustic leak detection device that can be used to detect leak points in pressure systems. This device detects air, gas, steam and liquid leaks using high frequencies and ultrasound waves.

product overview

Numerous industrial sectors employ PCE-LDC 15 Ultrasonic Leak Detector. The leak detector, for instance, is utilized with refrigeration systems, door seals, compressed air, gas, steam, and vacuum systems. The leak detector’s operating frequency is 40 kHz (2 kHz). The leak detector can be used in highly loud areas thanks to the soundproof headphones.

Wherever gases can escape from leaking pipe systems, a leak detector is utilized. The outflow frequently generates sounds in the ultrasonic range, which are unnoticeable to the human ear.

function PCE-LDC 15 Ultrasonic Leak Detector

The Ultrasonic Leak Detector works on the grounds of creating and recognizing ultrasonic waves. This gadget generates high-frequency ultrasonic waves that are used to find leakage sites. Due to the density and pressure of the air, ultrasonic waves propagate swiftly through space.

The pressure of these waves will drop if a leak point is along their path, and this pressure reduction will be returned to the device as a result of the leak point.

PCE-LDC 15 Ultrasonic Leak Detector features

  • 40 kHz working frequency ( 2 kHz).
  • Use of more than 10 hours.
  • A number of attachments.
  • A transit scenario for security.
  • Touchscreen makes it simple to operate.
  • Noise-canceling headphones.
