Thermocouple Tips

Thermocouples are the most popular temperature sensors. They are cheap, interchangeable, have standard connectors and can measure a wide range of temperatures. The main limitation is accuracy, system errors of less than 1C can be difficult to achieve.

Fieldman Sensors Pvt Ltd has develop and design thermocouple tips to detect and measure temperature using thermocouples of various types like B, K, R and S type.

We manufacture expendable immersion type thermocouple tips with spiral cardboard paper tube which are fitted on to lance pipe and used to take the temperature of molten metal in foundry and steel plants.

When immersed in the molten metal for 4 to 6 seconds the process of milivolt transfer to the microprocessor starts and the temperature is displayed on the display unit.

Technical specifications:

Type B (Platinum / Rhodium)

Suited for high temperature measurements up to 1800C. Unusually type B thermocouples (due to the shape of their temperature / voltage curve) give the same output at 0C and 42C. This makes them useless below 50C.

Type K (Chromel / Alumel)

Type K is the 'general purpose' thermocouple. It is low cost and, owing to its popularity, it is available in a wide variety of probes. Thermocouples are available in the -200C to +1300C range. Sensitivity is approx 41uV/C. Use type K unless you have a good reason not to.

Type R (Platinum / Rhodium)

Suited for high temperature measurements up to 1720C. Low sensitivity (10uV/C) and high cost makes them unsuitable for general purpose use.

Type S (Platinum / Rhodium)

Suited for high temperature measurements up to 1720C. Low sensitivity (10uV/vC) and high cost makes them unsuitable for general purpose use. Due to its high stability type S is used as the standard of calibration for the melting point of gold (1064.43C).
