LS-1881/LU-80A
The controller controls up to 8 pneumatic circuit units.
The tester can control the pneumatic circuits simultaneously or individually.
The compact pneumatic circuit units allows saving space which reduces facility cost.
All the I/O wiring between LS-1881 and PLC can be done in the control panel.
The I/O unit, the controller and all the pneumatic circuits can be easily connected to each other with the dedicated cables.
Also there is a plan to connect it to fieldbus (DeviceNet), which helps simplify wiring.
Four languages can be selected from Japanese, English, Chinese and Korean.
Please select one, depending on where the machine is used.
USB Memory is included as standard.
LS-1881 stores up to 1000 test logs per pneumatic circuit.
The test logs stored in USB memory can be viewed or used for data analysis on a PC.
The test parameters can be stored in USB memory as well.
Loaded with the features to improve test efficiency and test accuracy.
Equipped with High performance AD converter and Differential Pressure.
Provides stable differential pressure measurement with the resolution of 0.1 Pa.
Provides stable differential pressure measurement with the resolution of 0.1 Pa.
Compensates the error, which achieves test time reduction and eases management.
Mode to retest the part that fell in the “Uncertain Judgment Area” when the noises in test results are inevitable.
Checks sensor sensitivity and valve performance at each test as well as electrical performance.
Using a Leak Master, LS-1881can measure Equivalent internal volume, K(Ve), which is used to convert measured differential pressure into a flow rate.
Different test pressure and quick charge can be set for each channel by using an E/P regulator.
Pressurization time can be reduced depending on the test conditions.
