DTP-D-S
Large Displacement Measurement and High-Level Output in Each Capacity
DTP-D-S displacement transducers are designed to measure displacement by converting expansion/contraction of a sensing wire to electric signal by potentiometer. Four models are available with rated capacity 500, 1000, 2000 and 5000 mm, all providing a high rated output of 5 mV/V. In addition, measuring force of the wire is constant, thereby making these transducers easy to use.
?? Compact, lightweight, and easy to install
?? Measurement possible with strain amplifier
?? Constant measuring force of the wire (with differences between pull-out and pull-in)
?? Stainless steel wire is used (SUS 304).

Notes:
1. DTP-D-A series cannot be used in repetitive tests for fatigue life evaluation
2. Measurement is impossible when speeds of wire extraction/rewind are lower than follows;
- DTP-D-500S/1KS 10 mm/s or less
- DTP-D-2KS/5KS 20 mm/s or less
