Which Entube Voltage Sensor Is Right for You? Selection Guide

The Entube series includes compact voltage sensors and voltage dividers for differential, single-ended, high-bandwidth, and three-phase measurements. This guide compares Entube DE-HB, TE, DE, Z, SE, QE, and SE STD so you can narrow the selection by measurement type, bandwidth, input range, output format, and DAQ interface.

Start with the measurement type. Differential measurements point toward the DE family. Three-phase measurements point toward TE or QE. Single-ended divider applications point toward Z, SE, or SE STD. From there, compare bandwidth, input range, output range, and connection style.

Quick recommendation

  • Entube DE-HB: High-bandwidth differential voltage sensing.
  • Entube TE: Compact three-phase voltage sensing.
  • Entube DE: Double-ended line-to-line voltage measurement.
  • Entube Z: High-bandwidth single-ended voltage divider.
  • Entube SE: Single-ended voltage sensing for high channel density.
  • Entube QE: Three-phase plus neutral voltage divider.
