Three-wire Pt100.
Complies with BS1904 and DIN43760 (0.00385Ω/Ω/°C).
±0.1% of span ±1LSD.
Better than ±0.2°C any point, any 0.1°C range (±0.05°C typical). Better
than ±0.5°C any point, any 1°C range.
0.01% of span/°C change in ambient temperature.
Negligible.
Negligible.
Pt100 50Ω/lead: <0.5% of span error.
Automatic scheme.
150µA (approximately).
Break detect approx two seconds. Control outputs turn OFF (0% power);
Limit outputs turn off (goes into Exceed condition); Alarms operate as if
the process variable has gone over-range.
