Applications
The AMP-R10KE-5 is used in a variety of demanding applications, including:
Rotating Machinery Troubleshooting
Enhances the accuracy of fault diagnosis by providing clean, amplified signals.
Condition Monitoring
Enables real-time monitoring of critical components to prevent downtime and equipment failure.
Powered via a dual supply voltage of ±7V to ±18V, the AMP-R10KE-5 can be powered either through slip rings or external battery packs. For applications where the slip ring is subjected to high vibration levels, it is recommended that the GND (COM) connection is made through two slip ring channels to ensure optimal signal integrity.
Specifications: Strain Gauge Amplifier
The AMP-R10KE-5 offers a fixed gain of 1,000 X (other gain options from 1-10,000 X available upon request), and a high bandwidth of 10 kHz, making it suitable for capturing dynamic responses in high-speed machinery. The strain gauge amplifiers are encapsulated within an aluminium enclosure, ensuring durability and stability. Key specifications include:
- Bridge Supply: 5 VDC nominal, generated by a precision internal regulator
- Gain: Standard 1000 (customisable upon request)
- Dynamic Response: DC – 10 kHz (-3dB)
- Non-linearity: ±0.02% of Full Scale Range
- Common Mode Rejection (CMR): 100 dB minimum
- Gain vs Temperature: ±25 ppm/°C typical
The AMP-R10KE-5 is precision-engineered with laser-trimmed components, resulting in low offset voltage (40 µV) and minimal temperature drift (0.5 µV/°C). Designed to provide dynamic signal amplification, it ensures reliable performance even under demanding conditions. While the amplifier does not include a built-in provision for bridge balancing, out-of-balance conditions can be corrected using external resistors based on the specific installation.
Input pins (+IN and –IN) are protected against voltage transients up to ±40V, offering the durability needed for high-speed machinery troubleshooting and maintaining resilience in challenging environments.
