Description
The 330780-90-CN 3300 XL 11 mm Proximitor Sensor provides precise signal conversion for industrial automation systems. Designed for a 9.0-meter (29.5 ft) system length and panel mount, the 330780-90-CN accepts one 3300 XL 11 mm Proximity Probe and Extension Cable. It operates on –23 to –26 Vdc with maximum 12 mA consumption and maintains 50 Ω output resistance with supply sensitivity below 2 mV per volt input change. The 330780-90-CN features A380 aluminum construction, supports field wiring from 0.2–1.5 mm² (16–24 AWG), and functions from –52°C to +100°C operating temperature. This sensor transmits 3.94 V/mm (100 mV/mil) signals for axial position, rod drop, differential expansion, tachometer, and Keyphasor measurements. Its panel-mount design and SpringLoc terminal strips simplify installation while preventing fluid ingress, ensuring accurate automated monitoring in fluid film bearing machinery.
Applications
Measure Axial Position on Steam Turbines
The 330780-90-CN transmits signals from 3300 XL 11 mm probes to measure thrust bearing displacement. Its 3.94 V/mm output allows automated monitoring of axial movement.
Track Rod Position in Reciprocating Compressors
Connect 330780-90-CN to probes to monitor rod drop during compressor cycles. Field wiring supports 0.2–1.5 mm² and operation from –52°C to +100°C for accurate automated readings.
Capture Tachometer and Zero Speed Signals
The 330780-90-CN provides rotor speed and zero speed signals with supply sensitivity below 2 mV/V. SpringLoc terminal strips ensure secure 330 N connections for continuous data collection.
Monitor Differential Expansion in Rotors
Use 330780-90-CN to measure ramp expansion in turbines. Panel mount and aluminum construction allow installation in high-density areas without affecting 3.94 V/mm output.
Specifications
|
Input : |
Accepts one non-contacting 3300 XL 11 mm Proximity Probe and Extension Cable. |
|
Power : |
Requires -17.5 Vdc to -26 Vdc without barriers at 12 mA maximum consumption, -23 Vdc to -26 Vdc with barriers. Operation at a more positive voltage than -23.5 Vdc can result in reduced linear range. |
