Magnetic Sensors
Magnetic proximity sensors are characterized by the possibility of large switching distances, available from sensors with small dimensions. They detect magnetic objects (usually permanent magnets), which are used to trigger the switching process. As the magnetic fields are able to pass through many non-magnetic materials, the switching process can also be triggered without the need for direct exposure to the target object. By using magnetic conductors (e.g., iron), the magnetic field can be transmitted over greater distances so that, for example, the signal can be carried away from high temperature areas.

Field Probe for Electric & Magnetic Field Measurement
WP400-3
Wavecontrol presents a new and unique field probe for the measurement of electric and magnetic fields that integrates both E & H sensors within dimensions of only 3 cm². Which makes it unique is that Wavecontrol has managed to add an E field sensor in a basic structure of a classical 3 cm² field probe. It has been possible, therefore, to obtain a 3 cm² field probe without compromising the capability of assessing E and H fields of its 100 cm² big sister, the recognized and successful WP400.

Speed Sensors
DHE (Differential Hall Effect) sensors give an output when subjected to a changing magnetic field. The field is set up by a magnet inside the sensor body and changes when ferromagnetic teeth are passed beneath the sensor (no magnets are required in the target). To improve noise resistance, the sensor has two Hall effect elements and only responds to changes in magnetic field strength corresponding to tooth passing frequencies above 15Hz. As each tooth passes the sensor, the digital state of the output changes.

Cryogenic Temperature Sensors
Capacitance
CS capacitance sensors are ideally suited for use as cryogenic temperature control sensors in strong magnetic fields because they exhibit virtually no magnetic field dependence. Displacement current is not affected by magnetic fields. Consequently, temperature control fluctuations are kept to a minimum when sweeping magnetic field or when changing field values under constant temperature operation.

MPU- Passive Sensors
sensors of the MPU series are passive elements intended for measuring rotational speeds or speeds of moving parts. The measuring principle is based on voltage induction in the coil through a changing magnetic field, which is caused, for example, by a rotating ferromagnetic gear. The coil is wound on a magnetic core and led out via a cable or a plug. The sensors are manufactured with metric or inch threads or with a flange connection and deliver a sinusoidal output signal, the amplitude of which is proportional to the peripheral speed. They can be connected to Orbit Controls evaluation devices. An OC35-IMP transmitter is available for converting to square-wave signals.
