The 990-05-70-01-06 is a 2-wire, loop-powered device that integrates a proximitor sensor and signal conditioner to output a proportional 4 to 20 mA signal for PLC/DCS machinery control systems.
Non-interacting zero and span potentiometers under the Transmitter label supports loop adjustment
Test Input pin for quick verification of loop signal output, using a function generator as the input
Choice of DIN-rail clips or bulkhead mounting screws as standard options simplifies mounting
The 990-05-70-01-06 transmitter is used with centrifugal air compressors, small pumps, motors, or fans to provide a simple 4 to 20 mA proportional vibration signal to control systems. This two-wire, loop-powered device accepts input from the 3300 NSv proximity probe and its matching extension cable. Based on the part number configuration, this model specifies a 7.0-meter (23 feet) total system length and a full-scale range of 0 to 125 µm (0 to 5 mils) peak-to-peak vibration displacement.
The transmitter transforms the signal into an industry-standard 4 to 20 mA output, which serves as the input to PLC, DCS, or SCADA systems where machinery protection alarming and logic occur. This model includes 35 mm DIN-rail clips for installation and carries European (ATEX/IECEx) intrinsically safe and non-incendive hazardous area approvals for secure mounting in restricted industrial zones.

Thermal Power Generation Industry
Used for capturing main shaft vibration inside the bearing housings of boiler forced/induced draft fans and low-power auxiliary steam turbines.
Steel & Metallurgical Industry
Used for real-time runout monitoring on rotors of blast furnace Top Gas Recovery Turbine (TRT) units and high-speed converter dedusting exhaust fans.
Pharmaceutical Industry
Used for precision rotor monitoring on high-speed centrifugal separators for drug purification and centrifugal compressors in sterile air supply systems.
It is critical to strictly match the 3300 NSv proximity probe and extension cable system with a total length of 7.0 meters, and never alter the cable length to avoid disrupting the factory electromagnetic calibration. When mounted on a DIN rail the transmitter must maintain proper electrical isolation from the external metal enclosure to prevent ground noise from interfering with the measurement signal.
Since it utilizes a two-wire loop power configuration ensure the DC supply voltage remains within the specified safe window of 12V to 35V during wiring. Lastly when collecting raw on-site signals unfiltered dynamic voltage can be accessed via the dedicated coaxial port, but avoid applying external loads to this interface.
The Bently Nevada 990-05-70-01-06 needs a constant external loop power supply from +12 to +35 Vdc at the terminal block to maintain output precision across the entire frequency range. When using the Bently Nevada 990-05-70-01-06, the total combined length of the probe and extension cable must be exactly 7.0 meters to ensure the correct 7.87 mV/µm (200 mV/mil) prox-out scale factor.
990-05-70-01-06 is a loop-powered industrial vibration transmitter that converts eddy current probe signals into standard 4-20 mA current signals.
How do you use a product like 990-05-70-01-06?
Clip it onto a 35 mm rail and connect it to a compatible proximity probe system then wire its two-wire loop directly into the plant DCS or PLC modules.
What metrics of large machinery does 990-05-70-01-06 primarily measure?
It primarily measures the radial vibration at rotating machinery bearings and the dynamic shaft vibration of the rotor relative to the bearing housing continuously.
Does 990-05-70-01-06 require an external independent AC power supply?
No, it is a standard loop-powered device that draws operational power directly through the 4-20 mA DC current loop.
Which Bently Nevada probe series is compatible with 990-05-70-01-06?
It is specifically calibrated and matched for the Bently Nevada 3300 NSv proximity probe system.
