Rotary transmitters

Picture

Rotary transmitters

Rotary transmitters are used for signal transmission of transducers on a rotating part (e.g. engine shaft) to a stationary system (measuring instrument). They are exceptionally well-suited for the transmission of low level electrical signals.

Features: 
  • 1, 4, 8 or 12 channels
  • Speed: up to 40,000 rpm
  • Resistance: < 0.2 mOhms
  • Noise: 25 µV
  • Signal: up to 0.3 A per cell 60 V AC/DC
  • Very low inertia
  • No slip rings (non-contact)
  • Not sensitive to electromagnetic disturbance
  • Long lifetime

Specifications

Cell

12

Speed Ranges

Standard version : 0 to 20,000 rpm

High-speed version : 0 to 40,000 rpm

Total Noise

Typically 25 µV (max. 50 µV) with two cells in series at speeds from 0 to 20,000 rpm

Contact resistance of cell

Max. 0.2 milliOhms for 2 cells in series with an instantaneous variation from 0 to 5000 rpm

Insulation Resistance

More than 10 GigaOhms for two adjacent cells

Load Current

Max. 0,3 A per cell

Load Voltage

60V AC or DC between two cells or between cell and transmitter housing

Temperature Range

-25 °C to +60 °C

Thermal EMF

Typically 2 µV with two cells connected in series and at speeds from 0 to 20,000 rpm; corresponding to a possible error of 0.05% for a constantan-chromium nickel thermocouple, at a temperature difference of 600 °C

Connections (in/out)

Soldering contact

Cables (400 mm input and 400 mm output cables included)
