Reference output voltage : RATIO

Length Conversion Formula

Length = (measurement voltage - Min voltage) x gain
- Gain (m/V)
  = Max Length / (Max Voltage - Min Voltage)
- Max voltage
  = Reference Max voltage x (applied voltage V / 5V)
- Min voltage
  = Min reference voltage x (applied voltage V / 5V)
- Max reference voltage
  = Max voltage when 5V is applied
- Min reference voltage
  = Min voltage when 5V is applied
- Max length = Max fetch length

Wiring Connections

Notes

DWS is designed for operating at low speed wire drawing condition. It may behind its durability if high speed drawing is repeated.

Immoderate drawing may cause damages of internal spring and wire.

Check wiring connections before use.

12 months warranty is provided after released. Warranty provided only in case of using for designed purpose correctly.

Specifications, design and components can be changed without prior notice to improve its performances.
