Micro Three-Position Temp-Plate 160-165-171C

Temp-Plate Irreversible Temperature Recording Labels
Instant Temperature Record Temp-Plates are self adhesive temperature recording labels that can be read at a glance. Rated temperatures are printed at the sensor window. Each Temp-Plate contains one to several sealed heat-sensitive elements which change chemical structure when exposed to heat exceeding their calibrated temperatures. Each pearl gray indicator turns permanently and irreversibly black in less than one second and with ± 1% accuracy. With proper installation, Temp-Plates resist exposure to solvents, fuels, grease, oil, water and steam.

Where exacting temperature is critical, a Temp-Plate’s miniaturized size permits installation on parts and in areas where other recording instruments prove impractical. Temp-Plates provide a continuous  monitor for overheat that does not distort the temperature of the item being measured. Temp-Plates are easy to apply. For use during testing, Temp-Plates can be removed and entered into the test record log books. Available in a vast array of configurations and ranges. Nominal thickness is 0.01" (.3mm).

Temp-Plates are dedicated either °C, or °F, or both. Degree C scales  accommodate  international  use laboratories and the electronic industry, while degree F scales accommodate U.S. industry and aviation.

Quality Assurance
Temp-Plates are manufactured with the same meticulous care as all other Wahl instruments. Temperature accuracy is verified by calibration tests on all lots of chemical elements used in the manufacture of Temp-Plates. Records of the calibration data are on permanent file at Wahl where the accuracy of test instrumentation is traceable to the U.S. National Institute of Standards and Technology.

Calibration Method
Temp-Plates are tested by placing test samples close to calibrated thermocouples installed on the surface of a special heavy-duty hot plate. A temperature rise rate not exceeding 1°C  per  minute  is maintained and the temperature point where the color change occurs is carefully observed and recorded. The calibration accuracy of Temp-Plates is traceable by lot number.

Construction
Most Temp-Plates use a laminated construction consisting of a heat resistant plastic cover to encapsulate the temperature-sensitive chemical indicators and protect them from contamination from water, oil and solvents. The bottom laminate of plastic film contains pressure sensitive adhesive rated for elevated temperature installation. To install, remove the protective backing and apply t any clean, dry surface.

Temp-Plate Applications

Versatile, easy-to-read Temp-Plate Labels
help monitor and prevent overheating of valuable machinery, electrical parts, electronic components, perishable goods and other heat-sensitive materials and equipment. Temp-Plates are an economical, efficient tool for laboratory work, testing and quality control. Temp-Plates accurately:

Monitor overheating, wear and friction in machinery parts, such as bearings, gear boxes, transmission housings, radiators and heat exchangers.

Check overheating in electrical equipment, such as transformers, relays, generators, rectifiers, motor casings and bearings, underground power lines.

Audit overheated electronic parts, such as tubes, transformers, resistors, circuit boards and transistors.

Monitor commercial aircraft for preventive maintenance, such as engines, hydraulic systems, wheels, tires, brakes, heating systems, and avionics.

Prevent heat-related deterioration of materials, such as pharmaceuticals, pacemakers, foods, chemicals and film.

Protect computers and computer rooms, cargo compartments, blast tubes, rocket chamber walls, and bomb and ordinance storage areas.
