Add to Cart

The Entube-TE series is designed for high quality three-phase measurements in a very compact form factor without need for power supplies. This series covers the ranges from ±50V to ±1500V, with up to 85kHz bandwidth and 0.2% accuracy.
The Entube-TE sensor operates as a differential divider network with an anti-aliasing filter on its output. It generates a ±5V or ±10V scaled down version of the line-to-line and line-to-ground voltage on its input terminals. Depending on the software configuration, the sensor output phase-to-phase voltages for Delta configuration, or phase-to-ground for Wye configurations.
This signal can then be processed by most computer based measurement platforms.
One Entube-TE replaces 3 sensors, and only requires one cable for all three signals. This allows for very high channel densities, while delivering high performance for a low cost.

Surge Protection

The IsoBlock V devices are designed to survive and protect other equipment against harmful voltage surges. These depend on the duration but can go as high as 20x the rated measurement range for up to 5 microseconds.

Although Entube devices will continue to scale the outputs according to the input a maximum slighly higher than the output range, saturate and not go over range therefore protecting any connected DAQ.

Optional Filtering

Verivolt IsoBlock devices have a filtering stage that can be configured during manufacturing and serve as an anti-aliasing filter. This filter is a 3rd order filter and needs to be determined during the ordering.

High Input Impedance

Verivolt IsoBlock V devices have a high input impedance to reduce the unwanted effects of adding a load to a source. Also, the high input impedance increases device safety.
