MONITORING SYSTEM VSR-3 FOR SB BRAKES 1. Parts of VSR-3 system for SB brakes If the minimum brake pad thickness is reached, the sensors (A) A pair of Pt100 sensors (B) measures the temperature of the each brake pad. If the temperature is too high or if the temperature is unequal from left to right side the unit generates a signal that Stroke sensor The analogue sensor measures the position of the thruster piston rod. The reserve stroke is measured and checked that it is at the perfect position of 10 mm when the brake is correctly closed. The maximum measurement range is 100 mm. Pad wear and...
