PC USB 24-bit dual-channel 48 kSPS 0.03Hz~23kHz IEPE Data Acquisition Interface
VT IEPE-2G05 is a 24-bit, dual-channel, USB data acquisition interface specially designed for use with IEPE sensors such as IEPE accelerometers, IEPE microphones and IEPE hydrophones. Each channel has six calibrated voltage measurement ranges for easy calibration to sensor sensitivity: ± 250 mV, ± 500 mV, ± 1 V, ± 2.5 V, ± 5 V, ± 10 V, and a built-in 24V 4mA current source to drive an IEPE sensor directly. It contains a hardware high pass filter with 5 selectable -3dB corner frequencies: None (0.03Hz), 1.8 Hz, 119 Hz, 236 Hz, 464 Hz. The signals sensed by the IEPE 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 measurements as simply as plug & play. No external power supply and driver installation is required. It is a truly hassle-free portable noise and vibration measurement solution.
VT IEPE-2G05A has the same specifications as VT IEPE-2G05, except that its Channel B has a 20 dB higher analog gain, with its voltage measurement ranges changed to: ± 25 mV, ± 50 mV, ± 100 mV, ± 250 mV, ± 500 mV, ± 1 V. The increased gain makes it more capable of measuring low level signals such as a low-dBSPL sound.
VT IEPE-2G05B has the same specifications as VT IEPE-2G05, except that its two input channels A & B have a 20 dB higher analog gain, with their voltage measurement ranges changed to: ± 25 mV, ± 50 mV, ± 100 mV, ± 250 mV, ± 500 mV, ± 1 V. The increased gain makes it more capable of measuring low level signals such as a low-dBSPL sound.
VT IEPE-2G05C/D/E have the same specifications as VT IEPE-2G05, except that their Channels B have a 40 dB higher analog gain, with their voltage measurement ranges changed to: ± 2.5 mV, ± 5 mV, ± 10 mV, ± 25 mV, ± 50 mV, ± 100 mV. The increased gain makes them more capable of measuring extra low-dBSPL sound. Their Channels A have a 0dB /20dB / 40dB higher analog gain respectively than that of VT IEPE-2G05.
All the above models can be switched to a voltage measurement mode (e.g. for the purpose of accepting the voltage pulses output by a non-IEPE tachometer) by cutting off the 24V 4mA constant current supply through an internal DIP switch in each channel. The 4mA constant driving current can be modified as well (e.g. for the purpose of driving a very long cable). These customizations are recommended to be done in the factory upon request before shipping.
It is possible to run multiple VT IEPE-2G05/A/B/C/D/E using multiple instances of the software on the same computer.
