Heraus Class A/B PT100 M222 Thin film PT100 sensor element
Description:
1. Introduction
Thin film platinum resistance temperature detectors (Pt-RTD) consist of a thin film platinum deposited on a ceramic substrate. Thin film Pt-RTD’s provide cost advantages when compared to wire wound Pt-RTD’s because of their lower material cost factor.
2. Specification
1. Standard: DIN EN 60751 (according to IEC 751)
2. Temperature coefficient TC = 3850 ppm/K
3. Ceramic dimension:(L*W*H)3.0*2.0*1.0 3.2*1.6*1.0 5.0*2.0*1.0
4. Lead wire length:10mm
5. Lead wire material: Ni-Pt alloy
6. Specified current:1mA
7. Max current:2mA
8. Accuracy:1/3B,A,B,2B
| Accuracy | Deviation error | Deviation resistance(0 °C) | (α)(Ohm/Ohm/deg.C) |
| 1/3B | +/-(0.1+0.0017t) | +/-0.04 Ohm | 0.003851+/-0.000004 |
| A | +/-(0.15+0.002t) | +/-0.06 Ohm | 0.003851+/-0.000005 |
| B | +/-(0.3+0.005t) | +/-0.12 Ohm | 0.003851+/-0.000012 |
| 2B | +/-(0.6+0.01t) | +/-0.25 Ohm | 0.003851+/-0.000024 |
3. Features
