BENTLY NEVADA 330780-51-CN 3300 XL 11 mm Proximitor Sensor

Description

The BENTLY NEVADA 330780-51-CN 3300 XL 11 mm Proximitor Sensor is a component of the 3300 XL 11 mm proximity sensor system, designed for non-contact displacement and vibration measurement. It operates across a frequency range of 0 to 8 kHz, with core functions including processing signals from 3300 XL 11 mm eddy current probes and extension cables to output a voltage proportional to the distance between the probe tip and the target surface. Key technical specifications include a power requirement of -17.5 Vdc to -26 Vdc (without barrier) and a maximum current draw of 12 mA. Its linear measurement range starts at 0.5 mm (20 mils) from the target surface, extending to 4.5 mm (180 mils), with a sensitivity of 3.94 V/mm (100 mV/mil) ±10% when measured in 0.5 mm (20 mil) increments across the 4.0 mm linear range. This 5-meter system supports panel mounting, and features enhanced radio interference resistance to reduce installation complexity. Typical applications include radial vibration and displacement, axial displacement, key phase measurement, differential expansion measurement for steam turbines, and piston rod displacement measurement for reciprocating compressors. It is engineered for use on large rotating equipment in power plants, metallurgical facilities, oil refineries, and chemical plants to monitor rotor and casing vibration, velocity, acceleration, and displacement.
