MSI-GT2/3 Series Linear Position Sensor with SSI Output

The MSI-GT2/3 series is a rod-type, high-precision, absolute, non-contact magnetostrictive linear position sensor with a measuring range from 25 to 3800 mm.
Position measurement is performed using ring-type position magnets that move along the waveguide without physical contact. The sensor flange is made of high-quality stainless steel and designed for long-term operation in demanding industrial environments.

Design features

  • Output signal redundancy:
    • MSI-GT2 – dual redundancy
    • MSI-GT3 – triple redundancy

Due to the sensor head design, the sensor contains 2 or 3 independent sets of electronics and measuring waveguides.

  • Absolute linear measurement (output signals proportional to magnet displacement)
  • High accuracy: resolution up to 1 µm
  • Measuring length from 25 to 3800 mm in 1 mm increments
  • Linearity < 0.01%
  • Repeatability < 0.001%
  • Operating temperature up to 75 °C
  • Protection class IP67

SSI PROTOCOL TIMING DIAGRAM

This oscillogram shows a standard SSI transmission.

Channel 1 reads the clock signal "Clock (+)"

Channel 2 reads the binary code "Data (+)"

The interval between two transmissions (Monoflop time) is 16 microseconds. This performance corresponds to Temposonics V series sensors.

As a result, our sensors are compatible with all controllers currently available on the market.**
