product description 

Product details

The Bently Nevada 3300/20 Dual Thrust Position Monitor is an advanced device designed for the detection of thrust bearing failures. It continuously measures and monitors the axial position of the two independent channels, relative to the axial clearance inside the machine. The thrust ring is observed directly by installing an axial probe, and the measurement data provided by the monitor can accurately reflect the position of the thrust ring relative to the thrust bearing clearance.

Specification parameter

Input signal

The monitor receives signal input from one or two proximity probes with an input impedance of 10kΩ. The sensitivity can be set to 200mV/mil (8V/mm) or 100mV/mil (4V/mm) according to user requirements.

Power dissipation

In standard operating conditions, the monitor consumes 1.5 watts, ensuring efficient and stable operation.

Signal processing

In terms of signal processing, the monitor has excellent accuracy. At +25°C (+77°F), the typical error is ±0.33% of full scale, with a maximum error of ±1%.

exportation

The monitor offers flexible configuration options, allowing users to select output modes from +4 to +20mA, 0 to -10Vdc, or +1 to +5Vdc as required. The voltage or current output is proportional to the programmed monitor at full scale, with each channel providing an independent recorder output. In addition, the operation of the monitor will not be affected by a short circuit in the recorder output.

The monitor also performs well in terms of recorder accuracy. At +25°C (+77°F), for +4 to +20mA outputs, the error is ±0.7% of the signal and ±0.09mA offset; For +1 to +5Vdc outputs, the error is ±1.1% of the signal and an offset of ±10mV; For 0 to -10Vdc outputs, the error is ±1.1% of the signal and an offset of ±15mV.

The monitor also offers excellent performance in terms of output impedance and voltage adaptability. The impedance of its voltage output is 100Ω, and the minimum load resistance is 10 kω. When using the +4 to +20mA option, voltage adaptability ranges from 0 to +12Vdc and load resistance from 0 to 600Ω.

In addition, the monitor is equipped with a buffered sensor output with a coaxial connector on the front panel and a terminal connection on the back panel for each channel. All outputs are protected from short circuits. Its output impedance is 100Ω.

Sensor supply voltage

The user can select the sensor supply voltage of -24Vdc or -18Vdc as required in the power supply. Each monitor circuit board has a finite current function.

Look out

If you use both a 3000 series sensor and a 3300 series or 7200 series sensor in your monitoring system, be sure to contact your nearest sales professional for professional advice.

Alarm setting

The monitor supports the alarm setting function, and the user can set the alarm threshold according to the actual demand, so as to realize the real-time monitoring and early warning of the thrust bearing status. By responding to the alarm signal in time, users can effectively prevent the failure of thrust bearings and ensure the stable operation of the equipment.

Overall, the Bently Nevada 3300/20 Dual Thrust Position Monitor, with its accurate and reliable monitoring performance, is the ideal choice for thrust bearing condition monitoring in the industrial sector. Whether it is used to prevent equipment failure, improve production efficiency, or optimize equipment performance and extend equipment life, it can provide strong support for users.
