Product Details

measurement


The Entube-DE-HB series was designed to enable measurement of fast high voltage signals in industrial and research environments. The output of the Entube-DE-HB is a linearly scaled down version of the voltage difference between its two input terminals. This output can then be processed by a computer-based measurement system. The Entube-DE-HB series covers multiple input dynamic ranges with a 20MHz bandwidth, and 0.2% accuracy.

Entube


In addition to multiple dynamic ranges, the Entube-DE-HB can be ordered to have a single-ended (-S) or a differential-pair (-D) output. The single-ended version has a BNC connector at the output and can be selected to be ±5V or ±1V. The differential-pair version has a clamp-cage connector at the output and can be selected to be ±10V or ±1V. In both cases, the higher range is intended to be used with a high input impedance digitizer with a standard ±5 or ±10V dynamic range. The ±1V output range is intended to drive a 50 Ohm load (Single-Ended version) or a 100 Ohm load (Differential version) in applications where signal reflections must be avoided.

Frequently Asked Questions

The Entube DE is an analog sensor that scales down 1,000 volts to 10 volts. Being an analog sensor means that the lowest voltage that can be measured (or the smallest change) is determined by the number of bits your data acquisition device has.

For example, if you are using a 16-bit data acquisition device with an input range of ±10 volts (pretty common these days), the lowest voltage read would be 2,000 volts / 2^16 = 0.030 volts = 30 millivolts. You would then have to consider the maximum error of the measurement, which is a combination of the maximum error from the Entube DE plus the maximum error from the data acquisition device.

But as far as the lowest voltage that can be read (or the smallest change that can be detected), the resolution of the DAQ is the defining factor, so 30 milivolts.

The Entube DE-HB is a non-isolated sensor. If your application requires a high-bandwidth and galvanically-isolated sensor, the best option would be the IsoBand V or contact our team of engineering support who can guide you better.
