High Voltage Measurement Solutions

Knick Interface voltage and current transducers bring true CONTROL to electrical measurement applications across a wide-range of industries.

Precise measurement of both AC and DC systems is possible, while ensuring safety by way of high voltage galvanic isolation across input, output and power supply
channels. Quality craftsmanship and sound design bring peace of mind to applications where run of the mill voltage and current measurement products just will not do.

CONTROL means not having to make compromises with critical measurement needs. High voltage measurement applications demand this. Knick Interface stands
behind our voltage and current measurement solutions by off­ering a 5-year warranty on all products. High quality is ensured through careful product development,
comprehensive design verification, and 100% routine testing.

Machine Control - Motors, Drives, Electrical Test...

Machines and systems produced by electrical equipment manufacturers are only as dependable as the components used within them.  Operation of this equipment, within the many industries they serve, must offer safety, precision and reliability.  Voltage and current measurements are often a critical part of this operation.  In addition to using sensor data for machine control purposes, many machine builders are electing to also collect this data for purposes of predictive maintenance and energy optimization.  Knick Interface electrical measurement solutions have proven to show value in applications such as:

  • Current and voltage measurement for high voltage drive systems
  • Voltage and current data collection for energy optimization and predictive maintenance
  • Control signals for high voltage electrical test equipment

Heavy Industrial - Metals Processing, Chemical...

The environments often found within heavy industrial processing plants demand robust sensing solutions be used.  This is especially true for measurements designed for electrical systems, as isolation for safety purposes, due to high voltages encountered, is critical.  In addition, galvanic isolation found in Knick Interface high voltage and current transducers also help with accuracy, by minimizing effects seen with noise and ground loops found within the plant.   Installed applications include:

  • Current measurement and isolation on high voltage motors
  • DC voltage input on overhead crane systems
  • Energy storage levels for backup power systems
