A-28 Leak Tester
32 Part Programs with Application Flexibility
includes test type, timers, pressure, parameters, leak rates, calibration parameters, units of measurement, and digital input/output options.
Auto Calibration
routine tests master production part with internal calibrated leak standard to automatically establish the pressure-loss-over-time
(or flow) to leak rate relationship for the part.
External Leak Standard Connection as a configuration option
Envirommental Drift Correction
maintains calibration accuracy by monitoring and automatically making continuous small adjustments for changes in temperature and environmental conditions.
Quik Test
monitors the instantaneous in-test results and ends the testing process early when it is obvious that a reject or accept result is imminent
Self Test Functions
include internal pneumatic leakcheck, calibration verification, transducer zero and span calibration, and test regulator adjustment.
Compact Modular Enclosure
for easy installation and maintenance (includes all electronics and pneumatics) in a wall mount configurations.
Wall Mount
6.5"h x 9"w x 7.25"d
Modular Pneumatics
with manifold mounted valves, transducer, calibrated leak standard, and regulator.
Absolute Pressure Transducer
Monitors test pressures for all tests and displays pressure relative to atmosphere (gage pressure).
Utilized during Pressure decay leak standard, ΔP/ΔT or ΔT, and Occlusion tests.
Differential Pressure Transducer
Utilized during the Differential Pressure Decay Leak Standard test. Measures the difference between the test part and a customer supplied reference volume. This is a calibrated rate of loss test to a certified leak standard
High resolution 24bit A/D
converter and patent pending signal conditioning for fast, repeatable test results.
High speed, powerful computer with 32 bit processor
for fast, high resolution processing
Monitoring and Programming
Viaintegral operator panel or remote computer. Remote part program selection using Binary digital inputs (1 to 6 digital inputs), RS232, or Ethernet.
Operator Display Panel
makes operator interface simple, fast and comprehensive
Vivid, color LCD display with bar graph test results, digital test results, test parameters, counters, and test statistics. Icon menu screens for easy navigation.
• Test result lights for In test/Accept/Reject
• Language Neutral Keypad international icon design keypad accesses user friendly menu driven set up screens.
High Speed Communication via RS232 and Ethernet
includes test parameters, test results, counter information, and test statistics at baud rates up to 115200 for RS232. Test result output formats are selectable
Pressure Streaming
Test data output every 0.05 seconds via RS232 for plotting test curves.
Data Collection
Stores test results of leak/ flow rates, pressure loss, test pressure, time, date, and more for up to 5,000 tests.
Tooling Control
for simple applications includes an extend and retract output for part seal with one input start and part presence before start.
Easy setup performed within each part program.
Standard Integral 6Input/ 3Output Digital Interface
These inputs and outputs are independently programmable within each individual part program.
