The Bently Nevada 990-05-70-02-00 is a 990 XL 2-wire vibration transmitter with a 0-5 mil range. It converts proximity probe signals into a 4-20 mA output for direct DCS/PLC integration.
The Bently Nevada 990-05-70-02-00 functions as a self-contained, 2-wire transmitter that converts a proximity probe signal into a standard 4-20 mA current loop. This device integrates the functions of a Proximitor sensor and a signal conditioner into a single unit. It measures the radial vibration of a rotating shaft and outputs a signal proportional to the overall peak-to-peak displacement. By providing a direct interface to a Distributed Control System (DCS) or Programmable Logic Controller (PLC), the 990 XL eliminates the need for specialized vibration monitor racks in non-critical machinery applications.
Engineers designed the 990-05-70-02-00 to operate within a 5-meter total system length, typically pairing it with a 3300 XL 8mm proximity probe. This specific model features a full-scale range of 0-5 mils (0-125 µm) peak-to-peak, providing high-resolution data for precise vibration tracking. Furthermore, the transmitter includes a “Prox Out” buffered signal port. This allows technicians to connect portable diagnostic equipment, such as a field data collector, to view the raw vibration waveform without interrupting the 4-20 mA control loop.
This vibration transmitter actively simplifies the integration of machinery protection into existing plant control architectures. Because it uses a standard 4-20 mA interface, it allows for easy trending and alarming within the plant’s HMI environment. Consequently, maintenance teams can implement cost-effective monitoring for general-purpose equipment like motors, fans, and pumps. The 990-05-70-02-00 ensures that operators receive immediate notification of mechanical issues such as rotor imbalance or shaft misalignment, thereby preventing unexpected downtime.
Primary industrial applications include:
Bently Nevada utilizes high-durability materials to ensure the 990-05-70-02-00 performs reliably in punishing industrial environments. The transmitter housing features excellent resistance to electromagnetic interference (EMI), which prevents signal noise from affecting the accuracy of the 4-20 mA loop. Additionally, the DIN rail mounting option facilitates rapid installation within existing electrical cabinets. The unit also includes internal protection against reversed polarity and over-voltage, ensuring that the electronics remain safe during commissioning and routine maintenance.
