CNC Precision Machined Chromel Pin for Thermocouple Conductor
Production Introduction:
The most common chromel alloy is made of approximately 90 percent nickel and 10 percent chromium that is used to make the positive conductors of ANSI Type E (chromel-constantan) thermocouples and Type K (chromel-alumel) thermocouples. It can be used at temperatures up to 1,100 掳C in oxidizing atmospheres. There are also three other type of chromel alloys available for other purpose, Chromel A, Chromel C, Chromel R.
Chromel A and Chromel C are often used for electric heating elements, resistance windings, and hot wire cutters, Chromel R is only developed as a woven fabric by NASA for spacesuits.

Chromel Conductor Pin Application:
Our machined chromel pins are used as positive conductors in Type E thermocouples and Type K thermocouples.
Chromel鈥揷onstantan thermocouples (type E) give the highest measurement sensitivity of 68 渭V/掳C, with an inaccuracy of 卤0.5% and a useful measuring range of 鈭?00 掳C up to 900 掳C. Unfortunately, while they can operate satisfactorily in oxidizing environments when unprotected, their performance and life are seriously affected by reducing atmospheres.
Chromel鈥揳lumel thermocouples (type K) are a widely used general purpose device with a measurement sensitivity of 41 渭V/掳C. Their output characteristic is particularly linear over the temperature range between 700 掳C and 1200 掳C and this is therefore their main application, although their full measurement range is 鈭?00 掳C to +1300 掳C. Like chromel鈥揷onstantan devices, they are suitable for oxidizing atmospheres but not for reducing ones unless protected by a sheath. Their measurement inaccuracy is 卤0.75%.
