transmitter utilizes eddy-current proximity measurement technology to monitor axial shaft position relative to the machine casing. Proper operation depends on compatibility between the transmitter, 3300 NSv probe, and specified 7.0 m transducer system length. During commissioning, gap voltage verification is commonly performed to confirm operation within the calibrated linear measurement region. For proximity measurement systems, nominal operating targets near -10 VDC are frequently used to validate probe positioning, transducer scaling, and thrust measurement linearity before placing the machine into service.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What happens when a Not OK condition occurs?\u003c\/strong\u003e\u003cbr\u003eA: The transmitter forces the output current below 3.6 mA within 100 us after a fault condition is detected.
