First Class performance to IEC61400-12-1 standard
Overview
The W200P-1 has excellent sensitivity and is suitable for remote operation. It incorporates a precision micro-torque wire wound potentiometer mounted in an all-weather, corrosion-resistant case. The potentiometer has the lowest possible torque consistent with long life and reliable operation. Read MoreBenefits and Features
- Robust, precision instrument
- Field-proven track record
- Long cables and anti-icing heaters available to special order
- Fin and rotor attached by patented gravity sensitive fastener for rapid attachment and release in portable applications
Technical Description
The small gap at North is filled to ensure smooth operation and a long service life. The precision ball-bearing races are corrosion resistant and protected against the entry of moisture and dust.
Marine Version Available to special order; call for further details.
