Kyowa DTPA-A-500 DTPA-A Wire-type Displacement Transduce
Made in Japan
Manufacturer: Kyowa Electronic Instruments Co., Ltd.
Model: DTPA-A-500
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.
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
