PRC has again achieved another milestone in designing, developing and manufacturing an intelligent version of leakage testing machine for flange. This machine is Water dip type suitable for Capacity of 12 Bar with Testing range of 0.1 Bar to 12bar. It is equipped with Curtain sensor for safety & photo electric sensor for part presence. It has got Electronic Controller with 20X4 LCD display with backlight for display parameters, 16 inputs and 16 potential free relay output, 8 keys key pad for parameter setting, Audio visual alarm Special feature:
Auto manual operation, All testing parameter to be changed by user as per requirement i.e. Clamping time, Pressure fill time, Testing time, Stamping time, Loading & unloading, Manual Auto Marking. It has got Well fabricated structure with guarding sections. The base plate will be machined and zinc plated to prevent rusting. Structure will be duly painted where ever required and leveling pads will be provided for +/- 110mm height adjustments. This is very much user friendly operation and audio visual alarm. User can run this machine without any problem for non stop performance.Features:
- Highly accurate & dependable
- Quick leak detection
- Multi-channel operation
- Smart pneumatic & electronic circuits
- Easy calibration through Leak Masters.
- PC Interface through RS 232 C
- Pressure Decay leak measurements
- Strain gauge based pressure transducers / transmitters.
Theory of working:
The original dry-air method is pressure decay, in which the test part is pressurized and then isolated from the pressure source. Because air moves from a high-pressure area to a low-pressure area, any decrease in pressure indicates the presence of a leak. Algorithms then convert pressure changes into an approximation of the leak rate.
