Its accuracy rating is measured from the TEST signal input to the voltage across a 250 Ω loop resistance. The device features non-interacting zero and span adjustments, ensuring easy calibration.\u003c\/p\u003e\u003ch2\u003eIndustry Applications\u003c\/h2\u003e\u003cp\u003eThis transmitter is ideal for monitoring axial thrust in steam turbines, compressors, and large pumps. For example, in a turbine system where axial displacement must stay within 0.6-0-0.6 mm, the 991-06-70-02-CN provides real-time feedback to the control system. Its Not OK\/Signal Defeat feature (\u0026lt;3.6 mA within 100 µs after a fault) prevents false alarms and protects equipment during transient events.\u003c\/p\u003e\u003ch2\u003eInstallation \u0026amp; Setup Guidance\u003c\/h2\u003e\u003cp\u003eMount the Bently Nevada 991-06-70-02-CN on a DIN rail within the specified environmental limits. Connect the 3300 NSv probe and extension cable to the input. Wire the 4-20 mA loop in a 2-wire configuration, ensuring power supply is between +12 and +35 Vdc. Verify loop resistance does not exceed 1,000 Ω including cable. Adjust zero and span using the external controls per your application’s full-scale range (e.g., 0.6-0-0.6 mm or 25-0-25 mils). The transmitter automatically enters a Not OK state if probe signal is lost or out of range.\u003c\/p\u003e\u003ch2\u003eMaintenance \u0026amp; Reliability\u003c\/h2\u003e\u003cp\u003eRoutine maintenance involves verifying probe gap and cable integrity. The 991-06-70-02-CN is built to withstand extreme temperatures and vibration. Its 23 mA current limiting prevents damage from loop faults. For long-term reliability, inspect connections annually and test the Not OK defeat function. The environmental limits (-35°C to +85°C operating) ensure dependable performance in outdoor or high-temperature settings.\u003c\/p\u003e\u003ch2\u003eSelection Guide \u0026amp; Purchasing Advice\u003c\/h2\u003e\u003cp\u003eWhen ordering the Bently Nevada 991-06-70-02-CN, confirm the full-scale option (-06: 0.6-0-0.6 mm), system length (-70: 7.0 meters), mounting option (02: bulkhead screws), and agency approval (CN).
