Specifications of Temperature Sensors

RTD Specifications

50M, 100M is Copper sensors. Ex-USSR standard. Linear characteristic. Low temperature stability. Sensor is exposed to deterioration effect. The lowest price.

Pt100, Pt500, Pt1000 - Thin-film platinum elements. International standard. Nonlinear characteristics. The best reliability and long-term-stability. The smallest sizes. Evaporated technology. High-resistive models have limits in the current.

50P, 100P -  Wire-wound platinum elements. Ex-USSR standard. Nonlinear characteristics. Long-term-stability. Big sizes. High prices.

Thermocouple Specifications

MKn -Type T - International standard. Specialization is low temperature, vacuum, inert and deoxidizing atmospheres, partly oxidizing atmospheres..

ХK - Type L - Ex-USSR standard. Good thermosensitivity. Can also operate in a reducing environment. Lack - no wires with modern types of isolation. 

ZhK - Type J - International standard. Good temperature stability. Workable in reducingatmosphere. Do not use grounded thermocouples.

ХА - Type K - International standard. Average temperature stability. The most commonly used type both in CIS and abroad. Rather a low price.

NN - Type N - International standard. Temperature stability is several times better than type K. Perfect for using in the range from 1000 up to 1250 °С.

PP -Type S, Type R - International standard. Excellent temperature stability and oxidizing atmosphere constancy. Dirt-sensitive. Expensive.

PR -Type B - International standard. More dirt-resistant and less heat-sensitive then P-platinum. Compensated by a common copper wire.
