DVF-11 Shinko 0-2500rpm Pulse Type Analog Tachometer

Description

The Shinko DVF-11 is a high-precision pulse-type analog tachometer designed for rigorous rotational speed monitoring in heavy industrial and marine environments. Utilizing a wide-angle 110mm square scale, this instrument provides clear, real-time RPM visualization with a full-scale sensitivity of 3mA. The unit is engineered for pulse-signal inputs from magnetic pickups or proximity sensors, featuring a rear-mounted gain adjustment for precise field calibration. Its robust construction ensures immunity to iron panel interference, maintaining accuracy in dense electrical enclosures. With a measurement range of 0-2500rpm (X100 scale), it serves as a critical diagnostic tool for monitoring engine, generator, and motor performance.
