Engineered for integration into PLC, DCS, and safety-instrumented machinery protection systems, the Bently Nevada 990-05-70-01-CN provides continuous proportional radial vibration monitoring via a robust 2-wire current loop. This transmitter conditions signals directly from a compatible proximity probe system to output a standard 4-20 mA analog signal, removing the need for dedicated monitor racks in the control architecture. The 990-05-70-01-CN is factory-calibrated for high-precision machinery diagnostics and features a 35 mm DIN rail mounting footprint for high-density control cabinet integration.

This transmitter is strictly calibrated to be compatible with a 3300 NSv proximity probe configuration. It cannot be used with standard 3300 XL 8mm or 5mm probes because of different scale factors and sensor gap behaviors. Ensure that the total system length (probe plus extension cable) matches the 7.0-meter configuration specification exactly; mismatching system lengths will result in linearity and scaling calibration errors.
Ensure that the 4-20 mA loop resistance is matched to the input voltage. If the voltage drops below 12 VDC at the transmitter terminal block during a maximum 20 mA loop excursion, the transmitter output will clamp, skewing high-vibration alarms. Avoid routing high-voltage motor power leads in parallel with the 990 transmitter cabling inside cable trays to prevent inductive noise injection.
During commissioning, verify the loop current with a high-accuracy digital multimeter in series with the return terminal. A static loop current of approximately 4.0 mA indicates a zero-vibration condition, whereas a current under 3.6 mA indicates a field sensor fault, probe disconnect, or open-circuit loop connection.
Mount the 990-05-70-01-CN onto a rigid 35 mm DIN rail inside a dry, low-vibration enclosure to minimize thermal drift and atmospheric contamination.
Connect the 3300 NSv proximity probe coaxial connector or cable to the designated PROX and COM terminal blocks using correct insulation and torque limits.
Route shielded, twisted-pair field cables to the + and - loop terminals, and connect the shield wire to the DCS or PLC instrumentation ground terminal only.
Apply 24 VDC loop power and verify loop current baseline performance at 4 mA with the machine in a shut-down, vibration-free state.
