ENTUBE DE-HB (1000V 10V SESC) 数据手册
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.

DESCRIPTION
The high voltage input signal connects to the sensor via two
clamp cage connectors. 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.

Connections for Entube DE-HB
A spring cage connector is used to input power to 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.

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.
