RAMSEY THERMO SCIENTIFIC SPEED SWITCH 60-23P

The Model 60-23P Under Speed Switch monitors speed by sensing a ferrous element attached to the rotating shaft or equipment. The detector generates impulses from the ferrous element and closes alarm contact when the time between impulses is greater than the time adjusted by the setpoint. The unit operates on the number of impulses

received rather than actual revolutions. Low speed range may be enhanced by increasing the number of ferrous elements on the rotating shaft.

• Non-contacting, proximity-type detector provides longer life and lower operating costs.

• Two-bolt mounting assures simple installation.

• Single-piece construction with no separate control unit. Provides ease when setting up and/or troubleshooting.

• Rugged housing is weather-tight, polyammide/fiberglass, and sturdy, yet lightweight.

• No moving parts and a longer trouble-free life.

• Alarm/delay: 10 second delay while rotating equipment reaches operating speed.

• Alarm to normal delay assures notification when speed drops below adjustable setpoint.
