LS-1881
The LS-1881 consists of a Windows® based controller unit that can handle up to 8 independent pneumatic units to achieve high speed production rates. This leak test package can also be used to simultaneously test multiple cavities on a single production part. Utilizing the same patented differential pressure sensor (DPS) as the LS-1842 air leak tester, the LS-1881 unit allows for a wide variety of quality control functions, as well as simple operation, all viewed and controlled from a large, full-color touch Panel LCD.
Multiple pneumatic circuit units
With the ability to connect up to 8 units, the LS-1881 reduces facility costs and the space required to operate. This allows for maximum efficiency and productivity in a limited space.
Simple wiring
Thanks to the simplicity of the wiring, the LS-1881 greatly reduces the number of machine building hours. In addition, it allows I/O units to be installed directly on the control board, providing a simple connection between the pneumatic circuit units.
Selective measurement screen
The LS-1881 allows the selection of different types of display such as offset value, test pressures and others, as well as the leakage value. Different modes accomplish this feature, giving the user the ability to select one, two, four or eight measurements as one time.
Substantial help mode
The help mode content allows the user to display lists of errors and probable causes to narrow down the source of the problem. When the LS-1881 exhibits a fault, it instantly checks the status of the input and output signals on the I/O monitor screen.
Quality control functions
The LS-1881 allows up to 1000 data values per station and can be plotted directly on the machine with the quality control (QC) function. Then, the measured data can be analyzed using a computer for further understanding and manipulation via a USB device.
