TQ442 proximity sensor Vibro- Meggitt

Designed for the contactless measurement of relative vibration and axial displacement in turbines, compressors, pumps and fans
2 or 4 mm measurement range (Ø8 mm sensor)
−40 to 180 °C operating temperature, IP68 protection rating
0.5, 1.0, 1.5, 2.0, 5.0 or 10.0 m integral coaxial cable
Certified for use in potentially explosive atmospheres

PRODUCT INFORMATION

8 mV/µm or 2.5 µA/µm (2 mm range), 4 mV/µm or 1.25 µA/µm (4 mm range), −40 to 180 °C, Ø8.2 mm tip, 90°-mount.

The TQ442 proximity sensor is a high-quality, high-reliability sensor for use with an EA402 extension cable and IQS450 signal conditioner, which provides either a voltage output or a current output.

The TQ442 is a 90°-mount sensor that is designed and built for long-term use in extreme environments characterised by high temperatures and/or hazardous areas (potentially explosive atmospheres).
