Charge Amplifier

Charge Amplifiers

Our distributed charge amplifiers are manufactured by Sinocera (Sinocera Piezotronics Inc.) which has a long history over 50 years in manufacturing high-performance piezoelectric ceramic materials, piezoelectric sensors and dynamic testing instruments. The quality management and quality assurance of the production system complies with the international standard ISO 9001:2008. Each finished transducer is tested and calibrated by a stringent quality control system at the factory before being distributed to the market.

Charge amplifiers are used to convert charge signals (from  piezoelectric transducer) into low impedance signals such as IEPE or voltage signals with low impedance voltage (eg. ±5V, ±10V) as following commonly used diagrams.

There are numerous models of charge amplifiers available with different form factors, functions, and features as following.

• Variation of size and shape: compact inline adapter (YE5857B), small industrial rugged enclosure (YE5851),  portable enclosure with LED display (YE5855A) and compact standard enclosures (other models).
• Number of channels: 1 or 6 channels
• Switchable current supply, gains and filters: Most of the models have switches to change the current supply, gain, low pass filter, high pass filer (highly flexible, universal, adaptable) while some models has been opted out switches and dials (compact, small size, fixed parameters).
• Option with TEDs: Most of models do not include TEDS function while the model YE5855A provides TEDS function.
