Series R03

Tension and Compression Force Sensors

Series R03 smart sensors are designed for tension and compression measurement applications in virtually every industry. Threaded holes on two sides can accept a variety of hooks and implements, making this sensor particularly well suited for inline tests.

Capacities available from 0.25 to 100 lbF [1 to 500 N]. Compatible with Mark-10 indicators (sold separately) through unique Plug & Test®

Requires a Mark-10 indicator, available separately.

  • Member of the Plug & Test® family of interchangeable sensors and indicators
  • Rugged aluminum housing
  • Measures tensile and compressive forces
  • NIST-traceable certificate of calibration with data is included. If the sensor is ordered with an indicator, a certificate for the set (indicator + sensor) can be supplied upon request, at no additional charge.
  • Warranty: 3 years
  • Accuracy: 
    ± 0.15% of full scale + indicator
  • Weight:
    0.4 lb (0.2 kg)
With Model 7i and 5i Indicators
