Ensure the proximity probe is gapped between 0.5 and 1.75 mm from the target. Connect a 3300 NSv probe and extension cable to the transmitter input. Wire the 4-20 mA loop in a 2-wire configuration with a power supply of +12 to +35 Vdc. Non-interacting zero and span adjustments simplify calibration. For Proximitor Sensor Output via BNC, keep leadwire length within 3 meters (10 feet).\u003c\/p\u003e\u003ch2\u003eMaintenance \u0026amp; Reliability\u003c\/h2\u003e\u003cp\u003eThis vibration transmitter offers exceptional long-term reliability with typical current limiting of 23 mA and robust CSA Division 2 approval for harsh environments.
