Rotational speed computer measurement and control device

◇ A brief overview

HE03 computer speed signal device adopts embedded system control and peripheral chip

is suitable for measuring and controlling the rotational speed or frequency of hydro-generator sets.

field display with standard analog output and programmable alarm Relay

The output of the device contacts.

◇ main technique parameters

1 ) input signal: Permanent magnet machine frequency or generator PT frequency ;

2) measuring frequency range:0.1~100Hz;

3) output signal: Five, six, seven, eight, nine, ten-way center speed of 5%ne, (15%ne),35%ne,80%ne, 95%ne,99%ne(100%ne),110%ne,120%ne,130%ne, 140%ne(can be arbitrarily adjusted within the range of the set value );
