Intelligent Pneumatic Circuit
Leak detection circuit with internal pressure detection method, available in Intelligent 1 Pneumatic Circuit and Intelligent 2 Pneumatic Circuit. The differential pressure sensor and air operated valves are integrated with the manifold in a highly durable structure that minimizes breakdowns. In each test, the differential pressure sensor and the valves are self-checked to ensure that the judgment result is reliable.
-
High-performance differential pressure sensor
The improved differential pressure sensor, which is the heart of the Air Leak Tester, and the high-performance AD converter have realized measurement stability in units of 0.1 Pa. These effects are expected to improve measurement accuracy and shorten test time.
-
Mastering/Master Preset
Error components due to adiabatic compression, deformation, etc. during measurement are extracted and compensated using the value, enabling testing with a considerable error component, reducing measurement time and at the same time facilitating control on the master side. In addition, the system follows gradual environmental changes, such as room temperature, to achieve more stable measurements.

- Safety and Reliability Enhancing Features

-
NR (Noise Reduction)
When the leak limit is lowered to pursue accuracy or to shorten measurement time, the ratio of noise to the measured value will increase. In the Noise Reduction (NR) mode, indeterminate judgment areas are set for the initial Detection, and if the work falls within one of these areas, the noise component is removed by repeating Detection so that false rejection of good works can be reduced.
-
Exhaust Interference Prevention
For a system with multiple leak testers, the exhaust process can cause large fluctuations in the source pressure. It can have a negative impact on the tester(s) that are still measuring. This function is provided to prevent this problem.

USB memory data storage
A USB memory can be used to store large amounts of data for long periods of time, and data can be easily transferred to a PC.
-
Multilingual
Allows you to switch the display between multiple languages, including Japanese, English, and Chinese.
-
I/O monitor
Check the connection of the signals with external PLCs, such as start/stop signals and pass/fail signals, on the screen. This is very useful when equipment is connected.
-
Quality management
The latest 1000 work data (5000 for LS-R902) can be stored and displayed in a graph, which is useful for monitoring changes in work characteristics and changes in the measurement environment. In addition, the Mastering characteristic graph makes it easier to set test conditions.
