Measurement Performance Enhancing Features
  • 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.

  • Temperature Compensation (ATC)

    When there are differences in the temperatures of the works, the detection capability is improved by compensating for the differences for measurement.

  • Leak calibratrion

    To display differential pressure due to leak in flow units such as mL/min, a flow coefficient (Equivalent Internal Volume) is required. There are two methods to measure this coefficient: the volumetric change method and the Leak Master method. In addition, the fully-automated ALC (volumetric change method) and the automatic Leak Master provide the K-check function that not only measures the flow coefficient but also automatically checks for changes in leak sensitivity.

  • 100 channels

    Up to 100 channels can be set to handle a wide variety of works.

Safety and Reliability Enhancing Features
  • Automatic setup

    Allows the timers to be set automatically for initial adjustment.

  • Blockage Check

    Memorizes the normal measurement status of secondary-side equipment and diagnoses whether external exhaust valves, switching valves, etc. are blocked.

  • Optimum Value Detection

    Detects the change in differential pressure in Detection, which is the most stable and has the least noise, and converts it into a leak value.

  • Password setting

    Allows users to change their password.

  • Manual valve monitoring

    Automatically checks the opening and closing of the manual valves used for leak check of the tester itself. Detects if the valve(s) are left closed after a leak check, preventing leak testing with the valves closed.

  • Calibration port

    A port provided on the front panel for daily inspection and leak calibration. Differential pressure and test pressure can also be inspected and calibrated.

  • 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.

  • External Exhaust Valve

    To prevent malfunctions due to water or oil inside the works entering the tester, an externally installed exhaust valve (optional) is controlled by the tester.

  • 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.

Functions related to the interface
  • Color touch panel LCD

    Easy-to-understand large color touch panel LCD allows intuitive operation.

  • Fieldbus (EthernetIP, PROFINET)

    By connecting the tester and PLC via a fieldbus, the communication cables can be significantly reduced, and settings can be easily made with the EDS file provided by us.

  • 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.

  • FTP function

    Allows you to send and receive files using FTP client software.

  • 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.

Pneumatic Circuit
  • Test pressure 2-port switching

    One of two different test pressures can be assigned to each channel. Switching between pressure and vacuum and fast charging are also possible.

  • Test pressure control by electro-pneumatic regulator

    Test pressure is remotely controlled by an E/P regulator. Different settings for each channel and high-speed charging are possible.

  • Bypass circuit

    To reduce pressurization time for large-volume works, the tester directly controls the valve of an externally installed bypass circuit unit (optional).

  • High-pressure compatible

    Supports leak testing at test pressures in excess of 1 MPa.
