What is an overheating location sticker?

Overheating location sticker is a flexible sticker like insulating tape, which irreversibly changes colour from white to black after overheating occurs.

Why and how

to use it?

The sticker should be placed on a visible surface of equipment: reductors, bearings, motors, contact connections, etc. Colour change indicates that something wrong happened, for example:

Oxidation of contacts

Breakdown of bearing

Oil leakage

and so on

Detection of such defects allows to take the necessary precautions before defense activation, emergency stop, failure of equipment or other malfunction occur.

Where to place

a sticker?

3

Select equipment, malfunction or failure of which leads to unfavourable consequences: power outage, shutdown of a process, breakdown of apparatus and other.

Usually these are:

——

Electric contacts and contact connections that supply crucial equipment

——

Shut-off valve drives, solenoid valves

——

Electric drives of conveyors, production lines and reactors


——

Pumps of different types


——
Heaters and radiators

——

Positioning and control systems' electric motors


——

Gearboxes and gears


——

Bearing housing


——

Piston blocks

Determine the MAX working temperature

Consult a reference data or place L-Mark Test sticker with several indication dots on different activation temperatures.

Wait until the equipment goes through various work cycles. The indication dots will reveal what MAX temperature was reached.

Add 10-20ºС to MAX temperature and place appropriate sticker. Its size must make it clearly visible.

As a result, all crucial equipment should be fitted with white marks.

Regularly check 

equipment

Line staff and managers should all learn the rule:

white-04.png

White colour - no overheating.

Everything works normally.

black-04.png

Black colour - something went wrong!

Look for cause!

It is advised to protect unserviсed or remote equipment with "ThermoSensor" automatic system.

What's next?

Detect and repair the cause of overheating, place a new sticker and continue working.

If the cause wasn't found place L Mark-Test sticker and monitor the highest temperature. The higher the temperatures are the faster the malfunction must be repaired.

Purchase a diagnostic test kit and keep it available. It will allow fast detection of overheating if something is wrong with the equipment (new unexpectable noise, vibration, odor, etc.)
