Low cost bearing monitor. Option for contact output. 20 year battery life. http://www.pmalert.com/

Sparky -

It looks like a great instrument but - can you address the use of temperature for monitoring bearing condition?

Thanks.

The "TIC" monitors the temperature of the bearing lubricant and alarms when overtemperature is reached. The lubricant is supposed to take heat away from the bearing and also provides enough viscosity to separate the balls from the races. If the "TIC" flashes "RED", either you lack lubricant, a bearing is overpacked with grease or some other condition exists that is causing the rotating equipment to run "hot". When the "TIC" flashes "RED" the operator can then contact maintance to further evaluate the situation.

Thanks Sparky!

I would like to see how to do the required connections as stated in the second last paragraph in your product supplement. How do you suggest to replace existing bearing thermocouples? How to determine the right temp set point? Rdgs

1) For required connections, see attached instructions. Let me know if it answers your question.

2) Check what viscosity is required for the bearing type. Then check lubricant Viscosity vs temperature table. You can get this information from your bearing and lubricant suppliers.

Warning: This is an ad for my site

The "TIC" has recently been installed as a lubrication alarm. The signal closes a contact in the PLC, which tells the automatic lube system to hit the bearing with a shot of lube.

The "TIC" is now available as:
-Stand Alone Unit with flashing alarm light
-Contact output Alarm Unit
-4-20ma Temperature Transmitter Unit
-We are now installing wireless systems on a limited basis until we have a little more history with wireless installations
