Applications

Flaw Detection in Conveyor Line in Steel Mill

By using the filing function, which operates synchronously with external signals, data can be acquired for a long term. Since the RA2000 Series is small and compact, it does not occupy a large measurement space.

Operation Test of Power Switchboards and Production Facilities

The RA2000 Series is used to measure the operation timing of relays and voltage and current changes in the main power for operation.

Torque Measurement of Engines or Motors

In automobile testing, measurement of revolution, strain,pressure, vibration, torque, temperature, etc is executed. The RA2000 Series incorporates a variety of amplifiers, which can eliminate the need to install separate amplifiers and thus enable operators to perform the tests in a small space.
By using the filing function of the RA2000 Series, long-term data storage in external media at a high sampling speed (200 µs max.) is possible.

Wide Variety of Tests in Railroad Car

The RA2000 Series can accept oil pressure, air pressure, and acceleration in its AC strain amp, and save the data in the MO directly.Since the RA2000 Series incorporates strain amplifiers, external amplifiers are not necessary, which makes the measurement system compact.
Also, a long-term multi-channel measurement is possible by using the filing function.

Governor Test

The RA2000 Series is used as a recorder for the governor test,in which changing signals such as water pressure, revolution, generator voltage, current, governor, stroke, and pressure regulation stroke are recorded.
Since the data saved in the memory can be automatically stored in a PC card,database creation is possible without expending excessive time and effort.After storing the data, you can confirm the data on the monitor, which eliminates errors caused by variations in reading by operators.

Drop Test for Package

A drop test for packages is performed in order to avoid the damage that may occur during delivery of packaged electronic equipment.
Generally, packages contain materials for packing to absorb shock. This test measures the impact acceleration to obtain the data that is used for the improvement of materials for packing. There are two types of accelerometers that can be used in the drop test: a piezo-electric type or a strain gauge type. The RA2000 Series supports both types.

Monitoring of Vibration Level of Rotating Machine

In order to maintain rotating equipment such as motors, gears, bearings, piezo-electric accelerometers are used to check their vibration level.In this case, a band-pass filter that picks up the signals in the vicinity of the frequency of the rotation is used and RMS conversion is performed based on the signals so that the level changes become more visible.Waveform judgment setting is also possible.

Magnus Test

A Magnus test is a test to examine the response of a sample of tissue that expands or contracts, such as the blood vessel,enteron, or trachea of a mouse or rat, to the medicine applied to the sample.
This test requires a lot of repetition work. The filing and trigger functions of the RA2000 Series provide automatic processing of this work.Moreover,since strain amps can be incorporated, a tension sensor can be directly connected to the main unit,thus eliminating troublesome cabling.In addition,an operator can examine waveforms on the monitor during data acquisition and readout current values calculated by physical conversion.
