FAQ
Q1: What is the main advantage of a metal diaphragm compared to a ceramic diaphragm?
A1: A metallic process diaphragm offers superior mechanical strength and shock resistance against water hammer and rapid pressure surges. It features a fully welded structure without internal rubber seals, preventing medium leakage and chemical degradation in harsh hydraulic and gas applications.
Q2: Does this pressure switch support remote parameter setting and diagnostic functions?
A2: Yes, equipped with IO-Link communication, operators can perform remote configuration, continuous parameter reading, and device diagnostics directly from the control system, greatly simplifying commissioning and predictive maintenance.
Q3: Can this pressure transmitter be customized for OEM machinery with specific process connections?
A3: Absolutely. As a direct manufacturer, we offer full OEM and customization services, including custom pressure ranges, thread types (G thread, NPT, Tri-Clamp), electrical connectors, housing branding, and factory pre-set switching points to match your system design.
