Model HI 5800 -Electronic Vibration Monitoring Switch
The Hardy HI 5800 The HI 5800 Switch provides high-end vibration protection in a small, lowprofi le package. When you mount it directly to your rotating or reciprocating equipment, it monitors signs of vibration and activates onboard relay when a high-level is reached.
This switch uses a piezoelectric crystal and state-of-the-art electronics to provide the highest degree of precision in this stand-alone monitoring system. Both the vibration level and the alarm time delay can be set in the HI 5800 via two adjustment ports on the front of the switch. The time delay will prevent nuisance alarms or shutdowns in the case of an inadvertent spike in vibration.
Alarm indication is provided via a bright LED on the switch, and the reset can be performed either locally or remotely. A Power LED provides indication of proper switch operation.
