PIM ZJK(ICP) Sensor Coupler - Extra Low-Noise Sensor Power Amplifier for ICP-Type Sensors (e.g. for low-noise connection to measuring and analyzing instruments)

PIM ZJK(ICP) Sensor Coupler - The ZJK(ICP) extra low-noise sensor coupler amplifier is primarily designed for connecting common ICP-type (piezoelectric with built-in charge amplifier) dynamic acceleration, pressure, force, and torque sensors to voltage input measuring and analyzing instruments, data loggers, oscilloscopes, and PC cards. The device is specifically developed for applications requiring low noise levels in laboratory and field measurements. It can be powered by up to 230V AC, but due to its low power consumption, it can also be operated by batteries or cells. With its modular design, it is available in half-width desktop housings with three or four channels, or in full-width enclosures with up to eight built-in channels.

Various sensitivity ICP sensors can be connected to the ZJK(ICP) unit, which provides power to the sensors. The signal amplification can be switched independently for each channel in 3 steps (Standard version: 1x, 10x, 100x. Different amplification levels per channel can be ordered, ranging between 1x and 100x). The ZJK(ICP) provides the sensor signal as an amplified and band-pass filtered (0.2 Hz ... 10 kHz), DC-offset-free AC voltage signal to the measuring instruments. Each channel is completely independent from the others.
