Honeywell's closed loop current sensors consist of a Hall-effect sensor mounted in an air gap of a magnetic core, a coil wound around the core and a current amplifier. The current carrying conductor placed through the aperture of the sensor produces a magnetic field that is proportional to the current. The core concentrates the magnetic field which is measured by the Hall sensor. The Hall sensor is connected to the input of the current amplifier, which drives the coil. The current through the coil produces an opposing field to that provided by the current through the aperture. The magnetic flux in the sensor core is constantly controlled at zero. The amount of current required to balance zero flux is the measure of the primary current flowing through the conductor, multiplied by the number of turns on the coil. This current can be expressed as a voltage by passing it through a resistor. Variety of package styles available.
Best Used For:
Applications requiring high linearity and accuracy, fast response and low temperature drift such as variable speed drives, overcurrent protection, current feedback control systems, robotics and welding power supplies.

Honeywell open loop current sensors consist of a Hall-effect sensor mounted in an air gap of a magnetic core. The current carrying conductor placed through the aperture of the sensor produces a magnetic field that is proportional to the current. Open loop current sensors measure dc and ac currents, and provide electrical isolation between the circuit being measured and the output of the sensor. Variety of package styles available.
Best Used For:
Applications requiring galvanic isolation such as battery circuit management.

VFD and SCR output waveforms are rough approximations of a sine wave. There are numerous spikes and dips in each cycle. ATR transducers use a mathematical algorithm called "True RMS," which integrates the actual waveform over time. The output is the amperage component of the true power (heating value) of the AC current waveform. True RMS is the only way to accurately measure distorted AC waveforms. Select ATR transducers for nonlinear loads or in "noisy" power environments.
The current waveform of a typical linear load is a pure sine wave. AT transducers measure the peaks of these sine waves, then calculate the average amperage. This works well on constant speed linear loads in a "clean" power environment. Select AT transducers for strictly linear loads on "clean" power.

Non-contact displacement sensors using eddy current technology measure distances, displacements, or positions of any electrically-conductive target. These objects may have both ferromagnetic and non-ferromagnetic properties. Due to the high insensitivity to oil, dirt, dust, moisture, interference fields, etc. the eddy current principle is ideally suited to applications in harsh industrial environments.
Eddy current sensors designed for industrial use in factory automation, for machine monitoring, for inspection and for measuring and testing.
