Flow Meter/Laser Interlock Control Board

Document #:

LIGO-D1101835-v7

Document type:

D - Drawings

Abstract:

This safety interlock circuit is used to detect the flow meter rate and measure the laser temperature and shut down the laser system if the coolant flow rate drops below adjustable preset level or the laser temperature is above preset level.
