1. The index number and measurement range
(1) heat resistance (t is the absolute value of the measured temperature, ℃.)
| Thermal resistance category | Temperature measurement range | Precision grade | Allowable deviation |
| Cu | - 50 ~ + 100 | ±(0.30+0.006) |t| | |
| Pt | - 200 ~ + 500 | A grade | ±(0.15+0.002) |t| |
| Class B | ±(0.30+0.005) |t| |
2. Thermocouple (t for actual temperature, allowing the temperature degrees are available, and also can use the percentage of actual temperature, said taking large amounts.)
| Degree, | Tolerance level | |||
| Ⅰ | Ⅱ | |||
| Tolerance values | ℃ temperature range | Tolerance values | ℃ temperature range | |
| K | Plus or minus 1.5 ℃ | - 40 ~ + 375 | Plus or minus 2.5 ℃ | - 40 ~ + 333 |
| ±0.004|t| | 375 ~ 1000 | ±0.0075|t| | 333 ~ 1200 | |
| E | Plus or minus 1.5 ℃ | - 40 ~ + 375 | Plus or minus 2.5 ℃ | - 40 ~ + 333 |
| ±0.004|t| | 375 ~ 800 | ±0.0075|t| | 333 ~ 900 | |
| S | + / - 1 ℃ | 0 ~ + 1100 | Plus or minus 1.5 ℃ | 0 ~ 600 |
| ±[1+0.003(t-1100)] | 1100 ~ 1600 | ±0.0025|t| | 600 ~ 1600 | |
| B | - | - | - | - |

2. Normal temperature insulation resistance
(1) thermal resistance
Thermal resistance at ambient temperature for 15 ~ 35 ℃, relative humidity is not more than 80%, test voltage is 10 ~ 100 v (dc) electrode and outer casing of the insulation resistance between 100 m Ω or higher.
2 thermocouple
Thermocouple in the environmental temperature is 20 + 15 ℃, relative humidity is not more than 80%, the test voltage for 500 + 50 v (dc) electrode and outer casing of the insulation resistance between 100 m Ω or higher.
3. The thermal response time
When the temperature appear step change, the instrument of current output signal changes to correspond to the step change of 50% of the time required, usually expressed as a tau 0.5, in general, tau 0.5 90 s or less.
4. The minimum in depth
Minimum in depth of not less than 50 mm.
5. Nominal pressure
Generally refers to the protection tube at room temperature by static external pressure and not broken, take 1.5 times the nominal pressure test pressure.Allows working pressure is not only related to protecting tube material, diameter, wall thickness, and structural forms, installation methods, inserting depth, and the temperature of the measured medium, flow velocity and variety.
