Remote Charge Converters

Product catalog summary
Overview: The document provides technical specifications and applications for the ICP100, ICP110, and ICP120 signal conditioners, which are charge preamplifiers designed for use with piezoelectric transducers.
Applications:
  • These devices are used as preamplifiers for piezoelectric transducers with charge output, particularly in situations where IEPE transducers are unavailable, such as high-temperature measurements or with very small transducers.
  • They are suitable for long-distance signal transmission due to their low impedance output and are compatible with standard instrumentation.
Properties:
  • The devices feature a charge input stage that is unaffected by sensor cable capacitance and are low noise.
  • They are powered by a constant current supplied via the output cable, eliminating the need for a separate power line.
  • Three models are available with different gains: ICP100 (0.1 mV/pC), ICP110 (1 mV/pC), and ICP120 (10 mV/pC).
Technical Data:
  • Input: Charge input, single-ended, UNF 10-32 socket with overvoltage resistance of 500 V impulse.
  • Output: IEPE compatible, voltage, single-ended, BNC socket with a linear output voltage range of > 6 VPP and output impedance of < 50 Ω.
  • IEPE Supply: Constant current 4 to 20 mA, compliance voltage > 18 V.
  • Output Bias Voltage: 9 to 13.5 V, depending on supply current.
  • Gain Stability: < 0.05 %/mA.
  • Frequency Range: 0.25 to 25,000 Hz (-3 dB), 0.4 to 12,000 Hz (-10 %).
  • THD: < 0.5 %.
  • Noise at Output: < 200 µV.
  • Operating Temperature Range: -20 to 80 °C (-4 to 176 °F).
  • Case Material: Anodized aluminum.
  • Mounting: With cable harness clamp.
  • Dimensions: 72 mm x 22 mm (length x diameter), without sockets.
  • Weight: 35 g (1.2 oz).
