Precision instrumentation engineered for extreme pressure containment, automated safety cut-offs, and seamless integration with Swiss PLC systems.
Switzerland represents the pinnacle of global industrial precision, where sectors like fine chemical processing in Basel, heavy machinery and robotics in Zurich and Winterthur, and high-head hydroelectric generation across the Valais and Grisons cantons demand zero-compromise pressure monitoring.
An Electric Contact Pressure Gauge acts as both a visual pressure indicator and a critical electromechanical switch. When system pressure reaches predefined threshold limits, the internal contact system triggers alarms, shuts off hydraulic pumps, or activates safety relief valves automatically.
For Swiss plant managers and machinery OEMs, compliance with European Pressure Equipment Directive (PED 2014/68/EU), EN 837-1 design criteria, and ATEX directive 2014/34/EU for explosive atmospheres is mandatory. Huzhou Accuracy Instrument Co., Ltd. supplies fully certified electric contact instrumentation engineered specifically to endure harsh operating environments while delivering micro-second switching responsiveness.
Selecting the right contact mechanism is critical to guaranteeing contact longevity, spark suppression, and operational safety in Swiss process automation.
Utilizes a permanent magnet attached to the setting arm to accelerate contact closure. Prevents arcing under slow pressure changes and handles high electrical switching loads (up to 30W/50VA).
Non-contact proximity sensors operating without mechanical wear. Designed for hazardous ATEX Zone 1 & 2 environments in Swiss chemical plants. Transmits contactless signals via isolated amplifiers.
Integrates solid-state pressure sensing element with SPDT/DPDT micro-switches. Enables precise setpoint adjustments, zero hysteresis, and long-term signal stability across temperature extremes.
