The Entube SE series is a family of voltage transducers from Verivolt designed for high quality single ended measurements in a very compact form factor, and without need for power supplies. This series covers the ranges of ±50 V to ±2000 V with up to 50 kHz bandwidth and up to 0.2% of signal accuracy. The Entube sensor operates as a differential divider RC-network. It generates a ±5 V or ±10 V signal of the difference between the two input voltages, which is then processed by a computer based measurement system.
