Installation Points

The overall length specification of the system remains consistent

Armored cable should avoid severe bending and crushing

Shielded wire is only grounded on one side of the preamplifier

Explosion-proof site should be constructed in accordance with standard specifications Applicable scenarios

Steam turbine, generator differential expansion and shaft displacement detection

Severe mechanical wear, long-distance wiring conditions

High-temperature plant, hydrogen generator, chemical explosion-proof area
