6.3 Tire Slip Monitoring – TSM (A-CS-TSM-KIT-485)
To avoid kiln deformation that can damage refractory kiln torsion must be kept within certain limits. Kiln shell torsion
is greatly affected by the degree of clearance between the tires and the kiln shell. The simplest and most accurate
procedure is to measure the kiln shell's rotational speed as compared to the rotational speed of the tires. The result
is termed as tire slip. The Tire Slip Monitoring System is an automatic measurement and registration system
designed to monitor tire slip and alert the user when the system exceeds user-defined limits.
For an overview of a CS400 system with TSM, see section 8.2
6.3.1 Delivery
The scope of delivery for the TSM accessory:
•
Position indicator with junction box, 3 position indicators delivered for monitoring of 3 tires
(each further tire requires an additional position indicator (A-CS-PI-KIT), up to 6 tires can be monitored
with the TSM system)
•
TSM Remote Control
6.3.2 Functionality
The TSM system monitors tire slip by measuring the rotational speed of the kiln shell and of each tire. The rotation
time differences between the shell and each tire are converted to a radial slip.
The electronics in the TSM remote control box captures the trigger signals from the different rings and send <ring
number> and <time stamp> to the PC via digital communication.
6.3.3 TSM Remote Control
The TSM remote control box contains a micro-PLC and an RS485 communication port, all in a protective housing.
The measured values for the kiln and for each of the tires are then sent to the computer through the RS485 port.
