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.

Antenna, Loop Sensor
EM-6873 | 20 Hz – 100 KHz
The EM-6873 Loop Sensor Antenna uses passive circuits to transform magnetic field components between 20 Hz – 100 kHz to an equivalent open circuit two-terminal voltage on the receiving instrument. Use of the conversion Factor Chart, supplied with each antenna, will yield the strength of the magnetic induction field referenced to a uniform field. The loop is electrostatically shielded and therefore is sensitive only to the magnetic component (B-field) of the electromagnetic fields.

Automated Systems
A conditioner is a device that is used to selectively adjust the magnetic strength of a part to a specified value. In the past, conditioners have been used to simply “knock-down” the magnetic field of low-coercivity magnet parts (such as alnico and ferrite) until a certain field level was achieved. The resulting part was slightly weaker, but had a field strength that was repeatable.

Near Field Probes 30 MHz up to 3 GHz
RF1 set
The RF1 near field probe set consists of 4 passive near field probes for making measurements in the development phase of E-field and magnetic field in the ranges of 30 MHz to 3 GHz on electronic assemblies. The probe heads of the RF1 set allow for measurements close to the electronic assemblies, e.g. on single IC pins, conducting paths, components and their connectors in order to localize interference sources. Field orientation and field distribution on an electronic assembly can be detected through a trained special use of the near field probe. The near field probes are small and handy. They have a sheath current attenuation and are electrically shielded. They can be connected to a spectrum analyzer or an oscilloscope with a 50 Ω input. They do not have an internal terminating resistance.

It can collect and store data (X, Y, Z and M) for later download or stream data live via USB connector. Both the instantaneous values of X, Y, Z and M, and their peak values, are displayed on the meter screen. "Peak" values are the highest values seen since the peak reset button was pressed. Maximum error of sensitivity is +/- 0.5 % of the reading, and the maximum error of the offset is +/- 0.50 milligauss. Range is +/- 1999.99 milligauss with resolution 0.01 milligauss (or 1 nT) over the full range, displayed simultaneously for X, Y, Z and M.

The Model 8515-D is easily adapted to a wide range of production and laboratory demagnetizing requirements. A modern solid-state electronic control circuit, coupled with a rugged, heavy-duty discharge SCR and fixture, make this demagnetizer a highly reliable, low maintenance unit. The electronic voltage control circuit prevents the Model 8515-D from being discharged before the preset energy level has been reached, avoiding incomplete magnet desaturation. An easy to read front panel meter monitors the capacitor voltage. The energy storage level can be easily changed in the field. Integral electrical interlock and fail-safe circuitry provide a high degree of operator safety.

Magnetic Resonance Instruments
Integrated Dynamics Engineering
MRI systems represent a significant investment. As magnetic resonance images can be distorted by electromagnetic fields, frequently the location is isolated by passive shielding to somewhat insulate the detectors from image distorting EMI. But for a fraction of the cost of the machine an active EMI compensation can fully protect the image from damaging fields generated by other electrical equipment, passing traffic, elevators or other nearby equipment.
