Whole system accuracy of instrument and sensor, as listed in Table below

Characteristics:

Thermocouple’s cool end compensation mode:

Use 4-wires PT100, manufactured by our company, to compensate. Measuring mode of cool end pt100: 4-wires mode. The detecting current changes direction actively to eliminate the contact potential. The real coefficient of PT100 can be input into instrument. compensation accuracy≤0.01℃

Compensation mode and result:

By using our patented thermocouple’s cool end compensation pattern, widely changing temperature(gradient≤0.03℃/S)has no impact on accuracy.

Application:

Suitable for situation that requires high accuracy when temperature changes widely

Suitable for long-distance measurement, such as oil well of thousands of meters

Suitable for surface measurement. The line of type T thermocouple can be manufactured as slender as 0.15mm to reduce the impact of heat-conducting mostly and guarantee the measuring accuracy.

Suitable for precise measurement, such as verification of temperature field of sterilizer, verification of temperature field of verification furnace, furnace temperature detection of heat treatment.
