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.

RTD Type |
Tolerance Class | Temperatue Range, °С | Acceptable Accuracy, °С |
| 50М, 100М | В | -50 to 180 | ±(0,25+0,0035t) |
| Pt100, Pt500, Pt1000, 50P, 100P | 1/3В | 0 to 100 | ±(0,10+0,0010t) |
| А | -30 to 350 | ±(0,15+0,0020t) | |
| В | -196 to 500 | ±(0,30+0,0050t) |
* - no sense to order Class 1/3B and A for meters or controllers with R0 correction and deviation function
Thermistor Specifications
| Type | R25Ом | В25/В85 | Acceptable Accuracy В25/В85, % | Temperature Range, °С | Acceptable Accuracy R25,% |
| 10k NTC FT003 | 10000 | 3970 K | ±1% | -40...120 | ±1% |
* - in PJSC TERA’s thermistor meters and controllers acceptable deviation is 0,1°С after R25 correction and deviation

3 - three-wire 2Х2 - double-wire with 2 sensorsЧЭ 2I - double grounded
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.
