Technical data
| insulation resistance | When the ambient temperature is within the range of (15-35) ℃; |
| When the relative humidity is less than 80% | |
| The insulation resistance value of platinum resistance should be greater than 100M Ω | |
| Self heating effect | Thermal resistance allows a maximum measured current of 2-5mA; the resulting temperature rise is not greater than 0.3 ℃ |
| Extension tube | Stainless steel, length 50mm |
| Minimum depth of placement | ≥50mm， Excluding special products |
| process connection | Stainless steel, threaded |
| Protection tube | Stainless steel, 4mm, 6mm, 8mm |
| response time | t0.5，10s～120s |
| accuracy class | Pt100, Class A: ± (0.15+0.002 | t |) |
