CompareThermometer
| Measuring Principle | |
| Characteristic / Application | metric style modular temperature assembly threaded process connection without neck |
| Thermowell / protection tube | without (not intended to use with thermowell) |
| Insert / probe | mineral insulated (MI), flexible |
| Outer diameter protection tube / Insert | 6,0 mm (0,24'') |
| Max. immersion length on request | up to 250,00 mm (9,84'') |
| Material protection tube/ thermowell | 1.4404 (316L) |
| Process connection | male thread: G1/2" |
| Tip shape | straight |
| Surface roughness Ra | 0,8 μm (31,5 μin.) |
| Operating temperature range | PT 100: -50 °C ...300 °C (-58 °F ...572 °F) |
| Max. process pressure (static) | at 20 °C: 20 bar (290 psi) |
| Accuracy | class A acc. to IEC 60751 |
| Response time | t50 = 4 s t90 = 8 s |
