PIM ZJK(ICP) Sensor Coupler - Extra Low-Noise Sensor Power Amplifier for ICP-type Sensors (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 used 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 designed for laboratory and field measurements requiring low noise levels. It can be powered by up to 230V AC, but due to its low power consumption, it can also be powered by batteries or cells. Thanks to 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 (increments). (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.
