SENSOR-PRESSURE SWITCH

摘要

FIELD: instrumentation engineering; monitoring, control and indicating systems as switch gear of electric signals used for check of pressure limiting magnitudes. SUBSTANCE: differential setting unit of pressure switch is made in form of adjusting bush secured in housing and spring-loaded rod passed through hole in adjusting bush; spring-loaded rod is mounted for exerting action on lever which is engageable with switch. EFFECT: enhanced reliability and reduced consumption of labor required for setting the pressure switch. 1 dwg
