PL60
Under Speed Switches
The PL60 Under Speed Switch provides low-cost, reliable
and a simple means of monitoring the rotational velocity
of a shaft or other rotating equipment. When the belt
speed or rotating speed slows down within the preset
range, the PL60 switch outputs a signal for either alarm
or shut down. This switch is housed in a weatherproof,
hermetically sealed anti-corrosive enclosure, designed
for exposure to harsh environments. |
