1. Instroduction
VT CAMP-2G05 is a 24-bit, dual-channel, USB data acquisition interface specially designed for use with sensors with electric charge output such as piezoelectric sensors. Each channel has a built-in charge amplifier with 12 calibrated charge measurement ranges for easy calibration to sensor sensitivity: ± 250 pC, ± 500 pC, ± 1 nC, ± 2.5 nC, ± 5 nC, ± 10 nC, ± 25 nC, ± 50 nC, ± 100 nC, ± 250 nC, ± 500 nC, ± 1 µC. High-precision capacitors with low dissipation factors, low dielectric absorptions and very constant capacitance values against temperature and humidity variation are used in the charge amplifiers to convert charge to voltage.
The charge amplifiers are equipped with an overload indicator and a reset facility. Each channel contains a hardware high-pass filter with 5 selectable -3dB corner frequencies: None (0.03 Hz), 1.8 Hz, 119 Hz, 236 Hz and 464 Hz. The signals sensed by the charge-output sensors can be amplified and output directly from
the stereo headphone jack even without running the PC software. When used in conjunction with the Multi-Instrument® software, the setup allows you to take reliable and quality vibration and noise measurements as simply as plug & play. No external power supply and driver installation is required. It is a truly hassle-free portable vibration and noise test & measurement solution.
VT CAMP-2G05A has the same specifications as VT CAMP-2G05, except that its Channel B has a 60 dB higher analog gain, with its charge measurement ranges changed to: ± 250 fC, ±500 fC, ± 1 pC, ± 2.5 pC, ± 5 pC, ± 10 pC, ± 25 pC, ± 50 pC, ± 100 pC, ± 250 pC, ± 500 pC, ± 1 nC. The increased gain makes it more capable of measuring low level signals such as a low-dB sound in water.
VT CAMP-2G05B has the same specifications as VT CAMP-2G05, except that its two input channels A & B have a 60 dB higher analog gain, with their charge measurement ranges changed to: ± 250 fC, ± 500 fC, ± 1 pC, ± 2.5 pC, ± 5 pC, ± 10 pC, ± 25 pC, ± 50 pC, ± 100 pC, ± 250 pC, ± 500 pC, ± 1 nC. The increased gain makes it more capable of measuring low level signals such as a low-dB sound in water.
It is possible to run multiple VT CAMP-2G05/A/B using multiple instances of the software on the same computer.
