Brake Linings

Brake Linings

Brake Linings

(OP)
I posted this in another forum but maybe you guys can help- I 've been asked to find a way to monitor temperatures on brake linings- I see there's been work done on tractor/trailer brake/wheel systems but are there commercial systems out there ?- my application is somewhat different- the system is parallel posts, and the linings are 18" wide x 1" thick x 8' long ( its for a mine winder- thought I might be able to adapt something) - problem originated when a small piece of lining broke off, became wedged between lining & brake path & started a small fire- we run the winder remotely & would take 20 mins to get to the winder - we are installing fire suppression but also need temp detection
Thanks

RE: Brake Linings

Not my area, but I imagine you could use an infared thermometer to measure the outside surface of the drum.

I think that an interface could be set up with a computer that would record these temperatures in real time.

With experimentation, you could determine the maximum rate of temperature increase, then create a program so that if this rate was exceeded, an alarm or corrective action was implemented. As I say, just random thoughts as this is definitely not my area of expertise.

RE: Brake Linings

You could drill into the edge of the lining(s) and insert  thermocouples.You could run the thermocouple output to a furnace controller and set it up to sound an audible alarm if the temperature set point was exceeded.

Thanks for the suggestions - I was thinking of thermocouples also- apparently a company similar to ours was doing the IR thing but had some problems and have removed their system- will try and find out why from them

Thanks

RE: Brake Linings

Is there a thermal tape product that could output a resistance to an alarm? You could stick it on there and monitor the whole lining. I would think if you are remote monitoring you need something of low power consumption.
