Sirrah TS19 / SI19 - Sway sensor

 

DESCRIPTION
SIRRAH TS19 / SI19

SIRRAH is a sensor giving angle positions of a hoisting system fitted with an infrared transmitter : to use for sway measurement.
The coordinates are evaluated as plus or minus relative to the axis of the detector.
In its SI19 version, SIRRAH is improved for outside handling applications on container quay crane. 
It is waterproof and insensitive to the ambient infrared.
The infrared beacon transmits I.R. modulated energy waves, which enables a good measure whatever the distance.
The safety measure is total.

 

USE 

SIRRAH fixed on the crane trolley analyses the beacon position fixed on the spreader.
It is the sway sensor function or positioning sensor X,Y of a load.
Its high speed of measure enables itself to enter in a sway readjustment loop. 

PRESENTATION 

SIRRAH is presented in a monolithical way, in a box including optics, electronics and the processor for the measurement control. A calculator or a PLC (not provided) can be directly connected to SIRRAH to enable the use with several softwares.
SIRRAH is associated to one I.R. beacon to put on the spreader. It is independent from the sensor and synchronises itself automatically on SIRRAH.
