Functional Features The Proximitor Sensor features improved RFI/EMI immunity achieving CE mark approvals without special mounting considerations. SpringLoc terminal strips facilitate robust field wiring. The 9.0 meter system length accommodates remote probe installations. The multiple agency approvals enable global deployment. The sensor is fully interchangeable within the 3300 XL 11 mm system.
Application Scenarios Large steam turbine generator monitoring, remote compressor monitoring installations, distributed machinery protection systems, hazardous area rotating equipment monitoring, offshore platform long-distance monitoring, power plant distributed control systems, petrochemical processing remote monitoring.
Performance Parameters The sensor delivers 3.94 V/mm sensitivity with linearity within ±0.10 mm over the 4.0 mm range. The frequency response extends from 0 to 10 kHz. The 9.0 meter system length maintains full signal integrity over the extended cable distance. The multiple agency approvals cover intrinsically safe and non-incendive installations.
Material Composition The housing is constructed from nickel-plated aluminum. Connectors are gold-plated brass. Terminal strips feature SpringLoc design.
Structural Characteristics The sensor features a compact housing for panel mounting. The mounting base provides electrical isolation. The sensor includes coaxial system connectors for probe and extension cable connection.
Working Principle The Proximitor Sensor generates a high-frequency RF signal transmitted through the 9.0 meter cable system to the probe tip. Eddy currents induced in the target surface modify the RF field. The sensor detects these modifications and outputs a DC voltage proportional to the gap distance.
