ENTUBE DE-HB (1000V 10V DIFFSC)

Entube DE-HB Specification Sheet for Verivolt Ultra-Compact, High-Bandwidth, Differential Voltage Sensor OVERVIEW 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 (±100V, ±200V, ±300V, ±400V, ±500V, ±750V, ±1000V and ±1500V) with a 20MHz bandwidth, and 0.2% accuracy. In addition to multiple dynamic ranges, the Entube-DE-HB can be ordered to have a single-ended or a differential-pair output. The single-ended version has a BNC connector at the output, and can be ordered as ±10V, ±5V or ±1V.

Use appropriate wire jacket and gauge, as well as creepage distance. For superior noise immunity, it is recommended to use a twisted pair from the high voltage source to the input of the sensor.

A single post screw terminal is used to ground the secondary side of the sensor. The signal out of the sensor comes in a BNC connector (singleended version), or a spring cage connector (differential-pair version). If signal reflections are a concern, place the sensor as close as possible to the high voltage signal source, and use the appropriate cable and load termination. If using a digitizer with BNC inputs, use a 50Ω coaxial cable and a 50Ω terminating load at the digitizer end. If using a digitizer with differential inputs, use a 100 Ω twisted pair and a 100 Ω terminating load at the digitizer end. – 65 to 90 °C 3.6” x 2.4” x 1.4” 198 g (7.0 oz) The schematic on the figure above shows how to connect the Entube-DE-HB between the high voltage signal source and the digitizer. 650 Washington St, San Francisco, CA 94111 Phone: 70VERIVOLT / (708) 374-8658 1 MERCHANICAL DIMENSIONS HARDWARE CONFIGURATION A. Ground sensor by connecting a wire from the ground to the standoff located next to the two spring connectors. Connect any 8V to 28V external power source to power the unit. A Standards and Certifications ● CE B. Insert a wire pair between each of these connectors and a corresponding current input on the DAQ. The polarity of the signal out is aligned with the input signals. C. On the primary side, connect the plus and minus signals. Use standard twisted pair. C B DANGER THIS SENSOR IS NOT A SAFETY DEVICE AND IS NOT INTENDED TO BE USED AS A SAFETY DEVICE. This sensor is designed only to detect and read certain data in an electronic manner and perform no use apart from that, specifically no safetyrelated use. This sensor product does not include self-checking redundant circuitry, and the failure of this sensor product could cause either an energized or de-energized output condition, which could result in death, serious bodily injury, or property damage. 2
