IEPE100

Product catalog summary

Overview: The document provides technical specifications and application details for the IEPE100 Remote Charge Converter, a signal conditioner designed for use with piezoelectric transducers.

Applications:

Serves as a charge preamplifier for piezoelectric transducers with charge output.
Ideal for mounting near the transducer, especially in high-temperature environments or when using very small transducers.
Supports long-distance signal transmission due to its low impedance output.
Compatible with standard measurement technology and powered via an IEPE-compatible output cable.

Key Features:

Charge input stage unaffected by sensor cable capacitance.
Low noise operation.
Powered by a constant current through the output cable, eliminating the need for a separate power line.
Three selectable gain ranges (0.1 / 1 / 10 mV/pC) via internal DIP switches.

Technical Specifications:

Gain: Selectable at 0.1 mV/pC, 1 mV/pC, 10 mV/pC with internal DIP switches.
Accuracy: Less than ±2%.
Measuring Ranges: 0.1 mV/pC: ±50,000 pC; 1 mV/pC: ±5,000 pC; 10 mV/pC: ±500 pC.
Input: Charge input connected to signal ground, BNC socket.
Overvoltage Resistance: 50 V impulse.
Output: IEPE compatible, voltage output connected to signal ground, BNC plug.
Output Voltage Range: ±5 V.
Output Impedance: Less than 100 Ω.
IEPE Supply: Constant current 4-20 mA, compliance voltage > 20V.
Output Bias Voltage: 11-16 V, depending on supply current and temperature.
Output Polarity: Non-inverted.
Frequency Range: 0.5 Hz - 23 kHz (-5%), 0.2 Hz - 33 kHz (-10%), 0.1 Hz - 65 kHz (-3 dB).
Noise at Output: Less than 50 µV.
Operating Temperature Range: -20 to 80 °C (-4 to 176 °F).
Temperature Coefficient of Gain: -0.01 %/K.
Case Material: Brass, nickel-plated.
Mounting: With cable harness clamp or plug into BNC input socket.
Dimensions: 44 mm x 24 mm (length x diameter), without sockets.
Weight: 55 g (2 oz).

Additional Notes: Specifications are subject to change without prior notice. The device is designed for robust performance in various environmental conditions.
