Sensor Linearity — Why It Matters
A Allen-Bradley 1442-DR-5850 has a specified linear range — the gap distance over which output voltage changes proportionally to target displacement. Outside this range, the output saturates or becomes nonlinear. A probe installed with incorrect gap (too close or too far) will report incorrect vibration amplitudes. We verify linearity on every sensor we ship: calibrated target, known gap steps, measured output. If the linearity curve deviates from specification, we do not ship. Printed test report included.
