Bently-Nevada 3300/20-03-01-03-01-00 Dual Thrust Position Monito

Bently - Nevada 3300/20 - 03 - 01 - 03 - 01 - 00 is a dual thrust position monitor, mainly used for thrust bearing position monitoring of industrial rotating machinery. The following is its related introduction:

Functional Features

Dual channel monitoring: With two independent channels, it can monitor two different positions of the same shaft ring or shaft at the same time, which can improve the accuracy and reliability of monitoring, and can detect thrust bearing failures at an early stage, which is of great significance to ensure the safe operation of the equipment.

High-precision measurement: The thrust position is measured by measuring the gap voltage with a proximity probe, which has high accuracy and high stability.

Multiple output options: Provides analog and digital outputs, the analog output can be user-programmed as + 4 to + 20mA, 0 to - 10Vdc or + 1 to + 5Vdc, and the digital output can be used for data transmission through communication protocols such as Modbus RTU, which is convenient for integration with other monitoring or control systems.

Configurable parameters: Users can configure the parameters of the monitor according to actual needs, including alarm set points, channel selection, sensitivity, etc. Sensitivity can be set to 200mV/mil (8V/mm) or 100mV/mil (4V/mm).

Status Indicators: Green and red LED indicators are provided for each channel to show the operating status of the monitor, sensor and field wiring, as well as alarm conditions.
