Using reference target 8X.
4
The term
edge
refers to a mechanical edge, such as the side of a gear tooth, passing under the device. Rising edge: from valley to approaching tooth.
Falling edge: from tooth to approaching valley.
5
The TPOS Air Gap Range is the range of installation air gaps within which the TPOS (True Power-On State) function is guaranteed to correctly detect
a tooth when powered-on over a tooth and correctly detecting a valley when powered-on over a valley, using reference target 8X or equivalent, as
specified in the Target/Gear Parameters for Correct TPOS Operation section in this document.
6
The Extended Minimum Air Gap is a range of installation air gaps, smaller than AG
(Min)
, within which the the device will accurately detect target fea-
tures but TPOS is NOT guaranteed to be fully accurate, possibly evaluating the initial valley as a tooth.
7
The Extended Maximum Air Gap is an extended range of installation air gaps, greater than AG
(Max)
, within which the the device will accurately detect
target features but TPOS is not guaranteed to be fully accurate, possibly evaluating the intiial tooth as a valley.
8
Relative Timing Accuracy is the change in edge position before the resulting change in device output; for a single device, over the full Operational Air
Gap Range, AG, and Operating Ambient Temperature, T
A
, range.
9
Phase Delay is the change in edge position at detection, through the full operational Tooth Speed, S, range for a single device, and at a single ambi-
ent temperature, T
A
, and installation air gap, AG.
