Linear displacement sensors can stay dumb

Users also were asked to identify future diagnostic requirements in their linear displacement sensor procurements, beyond those identified as currently required. Nearly 80% of users expected no additional requirements by 2007. Self-testing was again the most identified requirement, with 6% of users expecting to require this feature in the near term. Small segments of users identified myriad other requirements expected to be required in 2007. These include:

• Accuracy checking
• Calibration checking
• Fault annunciation
• Obstruction indication
• Open circuit indication
• Reference point checking
• Repeatability checking
• Sensor function checking
• Short circuit indication
• Target out of range indication
