PMA 15

High-temperature extensometer PMA-15

High-precision high-temperature extensometer up to 1700° in air for measuring lengths between 45 and 105 mm.

General information

  • The system is supplied without a cable for the encoder signal.
  • The system also requires a TF amplifier (modulator, demodulator, signal amplifier). This is not included in the scope of delivery.

Characteristics

  • Easy operation thanks to swivel-slide suspension and feed motor for probe fingers.
  • Quick test readiness.
  • Uncomplicated positioning of the probe fingers.
  • Cuff rings for adjusting the measuring length L0 not required on the tensile test specimen.
  • Variable adjustable initial measuring length L0 between 45 – 105 mm.
