As temperature sensors, fabricated thermocouples are used with display instruments, recorders, electronic regulators. They measure temperatures ranging form 0 ℃-800 of liquid, vapor, gas medium, and solid surfaces.
Fabricated thermocouple is mainly composed of temperature-sensing element, fixed install devices, and junction box.

| Type | Code | Graduation | Measurement Range | Limit of Error |
| Ni Cr - Cu Ni | WRK | E | 0-800℃ | ±0.75%t |
| Ni Cr - Ni Si | WRN | K | 0-1300℃ | ±0.75%t |
| Pt-13Rh/Pt | WRB | R | 0-1600℃ | ±0.25%t |
| Pt-10Rh/Pt | WRP | S | 0-1600℃ | ±0.25%t |
| Pt-30Rh/Pt-6Rh | WRR | B | 0-1800℃ | ±0.25%t |
Note: t is the actual temperature value of temperature-sensing element
| thermal inertia grade | time constant (sec.) |
| Ⅰ | 90-180 |
| Ⅱ | 30-90 |
| Ⅲ | 10-30 |

◆Nominal pressure: generally refers to rupture at operating temperature protection tube can withstand a static external pressure.
◆Minimum insertion depth: not less than 8-10 times the external diameter of its protective casing (except special products)
◆ Insulation resistance: When the ambient air temperature is 15-35 ℃, relative humidity <80%, insulation resistance≥5 MQ (voltage 100V). Thermocouple junction box with a splash, when the relative temperature is 93 ± 3 ℃, insulation resistance ≥0.5 MQ (voltage 100V)
◆insulation resistance in high temperature: insulation resistance among the thermal electrode (including double-supported), protective tube and double thermode should be greater than the value specified in the following table.
| operating temperature | Test Temperature(℃) | insulation resistance(Ω) |
| ≥600 | 600 | 72000 |
| ≥ 800 | 800 | 25000 |
| ≥1000 | 1000 | 5000 |
