Beskrivelse
Key Features
- Charge input terminal for piezoelectric type acceleration pickup
- Isolated 2 channel input
- Max. rated voltage to ground: 30 V AC or 60 V DC
- Acceleration pickup with built-in preamplifier can also be directly input (BNC terminal)
- Equipped with constant current source for driving preamplifier
- Even measure general voltage signals with high, 16-bit A/D resolution
- Equipped with anti-aliasing filter essential for FFT analysis
- TEDS compatible, automatic sensitivity setting
Charge-output type and voltage-output type acceleration sensors are supported
For example, an acceleration sensor affixed to the chassis on which the motor is mounted, when connected to the Charge Unit U8979, can measure vibrations being transferred to the chassis. The MR6000's or MR8847A’s FFT calculation function can be used to perform a frequency analysis of torque and vibration signals.
TEDS compatibility enables automatic setting of sensor sensitivity
TEDS (Transducer Electronic Data Sheet)-compatible sensors digitize the sensor information inside the sensor. By using TEDS-compatible accelerometers, you can set the sensitivity of the sensor with a single touch.
