The DTPA-A is a potentiometer-type displacement transducer. It converts expansion or contraction of a sensing wire to electric signal by a built-in potentiometer.
Rated Capacity: 500, 1000, 2000, 5000 mm Nonlinearity: Within ±0.3% RO Rated Output: 2.5 mV/V±10% Measuring Force: Approx. 2 N (Max 2.8 N)
Features
• Hardly kinking wire • High response (When the stroke is rated output: 1000 mm/s or equivalent) • New wire-winding mechanism enables less trouble. • Compact, lightweight, and easy to install • Constant measuring force • Measurement possible with strain amplifier
