WATER GATE OPENING INDICATOR Shaft-Rotation Type STX100 Series
Takuwa STX100 Series is a water-gate opening indicator by measuring a shaft rotation of hoisting device of water gate (suitable for Sluice,Radial). Measured data is indicated by a hand on large scale board, and optional 3 type sensors (Synchro transmitter, Potentiometer, Limit switch) are able to mount as option for output signal. It is widely used because of high durability vibration, temperature and noises.
Takuwa STX100 Series is a water-gate opening indicator by directly measuring a shaft rotation of hoisting device of water gate (suitable for Sluice, Radial). Measured data is indicated by hand on large scale board, and optional 3 type sensors (Synchro transmitter, Potentiometer,Limit switch) are able to mount as option for output signal. It is widely used because of high durability against vibration, temperature and noises.
Future :
- Wide Measuring Range (30 meter is possible)
- Available for Radial gate and Sluice gate
