The magneto resistive sensors detect the movement of ferromagnetic materials, by means of the change of the magnetic flow. They are available with (Series 350) or without (series 300) detection of direction of rotation.
They are suitable for rotary speed sensing, for detection of gearwheels and for standstill control. Areas of use can be heavy construction engines, rail vehicles, large diesel engines and -turbines. Rotary speed sensing is possible with gear wheels form module 1, with a max. switching frequency of 15 kHz.

Both the model 3310 and 3320 G-Loggers come complete with an RS-232 interface cable and the G-Logger Software Program which allows you to set up the G-Logger for a particular data acquisition mission, acquire your data,
and then transfer the resulting data to your in 95/98/NT4.0/2000 PC. No data acquisition card is needed because all the communication is handled via the RS-232 COM port on your PC. The G-Logger Software program is meant to be used in conjunction with a plotting program. Should you already own or choose to provide your own plotting software, the G-Logger Software Program can be set to output the data in ASCII comma delimited format which is readable by most any data graphing software
package.
The model 3310 is a standalone unit. The Model 3320 G-Logger is designed to be used with either one model 2420 triaxial accelerometer or up to 3 Model 2010 single axis accelerometers. In order to connect 1, 2 or 3 model 2010
accelerometers, a Model 3901 (tri-Y) Adapter Cable is also needed. This adaptor allows the 2010's to be separated by up to 6' from each other. A 10' extension cable is also included and can be inserted between the model 3320 G-Logger and the model 3901 (with 2010's connected to it) or between the model 3320 G-Logger and a model 2420 Triax.

We can look at any special cables requests
(connectors, marking, labels, armours,...)
and also repairs of cables.
Note :
max @ min temp.°C are based
on P.T.F.E. cables, if P.V.C. cable
is used, range will be +40°/+85°C.

DS-90 Rotary, Sine/Cosine Absolute,
Electric Encoder™
The DS-90 is a member of the DS series, which is based on Netzer Precision Electric Encoder™ technology. This, state-of-the-art, technology offers many features, some unparalleled:
- Lowest profile (? 10 mm)
- High precision, absolute position output
- High tolerance to temperature, shock and moisture
- Tolerance to EMI, RFI, and to magnetic fields
- Very low weight
The holistic (1) structure of the Electric Encoder™ provides generous mounting tolerance, thus obviating the need for internal ball bearings. The absence of bearings, flexible couplers, glass disc, light sources and detectors, along with very low power consumption, make the DS-90 encoder virtually failure free.
The internally shielded, DC operated DS-90 includes an electric field generator, a field receiver, a sinusoidally-contoured dielectric rotor, and processing electronics. The coarse/fine, analog output signals are proportional to the sine and cosine of the rotation angle.
Demanding applications suited to the DS-90 include: Aerospace, medical, instrumentation, automation, etc.

Our rotary Electric Encoders are tolerant to temperature extremes, EMI, RFI, magnetic fields, contamination, moisture, shock and vibrations. Their hollow, floating, rotor does not require bearings and is directly mountable on the host shaft.
The absence of ball bearings, glass disc, light sources and detectors, and low power consumption leave the Rotary Electric Encoder with virtually no failure mechanisms. It is, therefore, ideally suited to a wide range of applications, among them aerospace, military & defense, automotive, medical and robotic.
DS family of Rotary Encoders
The DS family of electric encoders provide exceptionally accurate, high resolution, absolute position. Their ring construction and very low profile allows compact, "friendly" mechanical integration. The DS family of encoders ranges from the DS-25 with 25mm OD and 7mm profile to the DS-247 with 247 mm diameter and 10mm profile.
