发明名称 MULTIPLE RANGE TRANSITION METHOD AND APPARATUS FOR PROCESS CONTROL SENSORS
摘要 A sensor system (10) includes a first sensor (12) for sensing a parameter in a first sensing range and providing a first sensor signal (24) indicative of the parameter. A second sensor (14) senses the parameter in a second sensing range and provides a second sensor signal (26) indicative of the parameter. The second sensing range is larger than the first sensing range and the first and second sensing ranges overlap in a transition overlap region. A sensor output device (18) provides a sensor output signal based on the first and second sensor signals (24, 26) by blending components of the first and second sensor signals (24, 26) according to a blending function such that the sensor output signal is single valued, has no induced hysteresis, and is continuously differentiable.
