TQ402 111-042-000-013 A3-B6-C050-D000-E100-F1-G100-H10 Non-contact Proximity Transducer
Description:
TQ402 111-042-000-013 is an essential component of the proximity measuring systems. As a transducer, TQ402 use a non-contacting measurement technique based on the eddy current effect to measure the distance between itself and a moving (vibrating) object. Usually, TQ402 is mounted on non-vibrating surfaces. With API 670 compliant, available for high-pressure and watertight applicantions, TQ402 111-042-000-013 widely used in turbines, alternators, turbo-compressors and centrifugal pumps.

TQ402 111-042-000-013 A3-B6-C050-D000-E100-F1-G100-H1 is Explosive EX na, 1/2″-20UNF body thread, 50mm body length, 0 mm unthreaded length, 10 meters integral cable length, with 10m flexible hose and 1 meter system length. 

Major Features:
▪ Conforms to API 670 recommendations
