AUTION
The standard API 670 (Machinery Protection Systems) of
theAmerican Petroleum Institute is directed at manufacturers
and users of machine monitoring systems.
The extension cable connects displacement sensor and driver
and, if present, forms an integral part of the complete system.
Deviation from best fit Straight Line refers to the deviation from
an ideal characteristic curve of the distance measurement (see
API 670).
ElectroMagnetic Compatibility.
The d.c. voltage at the signal terminal of the driver (oscillator/
demodulator) corresponds to the separation (GAP) between
target and sensor tip.
Incremental Scale Factor refers to the precision of the sensitiv-
ity (see API 670).
The nominal system length refers to the distance measured
from the sensor tip of the displacement sensor to the end of the
plug connector that is connected to the driver. It is either 5 m or
10 m. The actual system length is governed by the electrical
