Optimised for precise preform temperature control in vapour deposition processes, AMETEK Land’s Vapour Deposition Thermometer delivers a critical measurement for production of low-loss, high-bandwidth optical fibre.
VDT enables exact sighting onto the rotating preform for an accurate surface temperature reading, critical in controlling fibre strength and transmission quality. This ensures an efficient, high-yield process with less costly scrap product.
Only a non-contact infrared thermometer technology is able to achieve the precise surface temperature measurements required for the process. VDT’s 4.8-5.2µm waveband measurement means the preform is opaque and the measurement unaffected by flames, ensuring exceptional accuracy.
Able to operate as a standalone device or as part of a multi-thermometer system linked by our System 4 Landmark Graphic signal processor, VDT is ideal for vapour deposition processes in the glass industry.
OPTIMISED FOR YOUR PROCESS
With measurement ranges of 1000°C (2500°F) to 1800°C (4500°F), and a small target capability given by focusable 100:1 optics, VDT is custom-designed to sight onto the rotating preform with exceptional accuracy.
HIGHLY ACCURATE MEASUREMENTS
Cost-effective, productive manufacture of high-quality optical fibre requires precise control of preform temperature in vapour deposition processes. With a non-contact measurement accurate to <1°C (<2°F), VDT provides the accuracy needed to ensure efficiency and a superior product.
FLEXIBLE, MODULAR DESIGN
VDT is compatible with our extensive range of System 4 mounting accessories. It also uses industry standard outputs to suit any process monitoring, recording or control system, making it easy to install in your existing systems.
