INTRODUCTION
Improve diagnoses and preventative maintenance by 'listening' to ultrasound. Small defects, leaks etc, emit ultrasound, and the detector
converts the ultrasound into an audible signal. Ultrasound is highly directional, making pinpointing the source very much easier than when
listening to normally audible sounds. As well as locating defects in mechanical components and gas and hydraulic systems the detector can
also pick up the ultrasound from HT leaks and other sources of arcing. The ultrasound transmitter, when placed inside a vehicle, allows leaks
around seals to be pinpointed by the detector. Supplied with headphones and two extension probes. Kit supplied in storage/carry case.

CONTENTS & SPECIFICATION
A
The Receiver unit - an easy-to-use unit incorporating audio
feedback and a visual indicator for intensity of signal.
The receiver has a permanently fixed directional receiver
port, 3.5 mm stereo jack port, an on/off switch and controls
for setting the sensitivity and bandwidth of the unit.
B
The Transmitter unit sends out a 40 kHz pulse for use in
testing seal integrity in a non-pressurised vessel. The pulse
can be adjusted to various patterns. It is powered by internal
battery.
C
Anodised 300mm air probe
D
Anodised precision length contact probe.
E
Full-sized headphone set with 3.5 mm stereo jack.
Carrying case for storage and transportation (not shown)

Summary of Contents for Sealey VS919

  • Page 1 VS919 MODEL NO: Thank you for purchasing a Sealey product. Manufactured to a high standard this product will, if used according to these instructions and properly maintained, give you years of trouble free performance. IMPORTANT: PLEASE READ THESE INSTRUCTIONS CAREFULLY. NOTE THE SAFE OPERATIONAL REQUIREMENTS, WARNINGS & CAUTIONS.
  • Page 2 Simply converting the ultrasound frequencies to audible frequencies is not sufficient with regard to rendering a usable signal. It is for this reason that the VS919 Ultrasonic Detection Kit incorporates a process whereby the audible signal bears a close likeness to the natural incoming sample.
  • Page 3 MECHANICAL MALFUNCTIONS Fig.1. shows a typical use to inspect a potential wheel bearing problem with the VS919. In this case the air probe is used, the wheel is being turned while listening for the sound of the bearings. The tip of the probe is kept 2-3 inches from the inspection area. Response can sometimes be optimised by removing the wheel and using the contact probe to touch the stationary centre hub.
  • Page 4 After some experience testing ignition systems, you can tell if you have a plug or wire problem by the sound alone. When checking make sure you listen at both ends of the plug wire if you can to determine the problem area. Use the solid probe for this test. VS919 - 2 - 160306...
  • Page 5 Aeration detection equipment gives the signal that air is in the system, but not the location of the leak. Using the VS919 receiver in suspect areas, such as the head gasket, the water pump, and injectors, will usually detect the exact source of the leak.
