YTQ Series Safety Pressure Gauge
Product Overview
Section titled “Product Overview”The YTQ Series Safety Pressure Gauge is designed for pressure measurement with safety protection when sudden overpressure or elastic element rupture may occur. Its safety structure helps release pressure toward the back of the case.
Applications
Section titled “Applications”- Pressure measurement where sudden overpressure may occur.
- Sites requiring a safety baffle and rear release structure.
- Applications requiring dual-layer safety glass.
- Pressure indication with optional non-seismic or seismic construction.
Product Features
Section titled “Product Features”- Diaphragm back release device.
- Stainless steel safety construction casing.
- Dual-layer safety glass.
- Optional seismic function.
- Multiple mounting and connection options.
Product Principle
Section titled “Product Principle”When the pressure gauge encounters sudden overpressure and the elastic element ruptures, high pressure impacts the rubber gasket on the safety baffle and back cover. The rear cover is installed by gasket compression, so instantaneous high pressure first overcomes the gasket friction, blows open the back cover and releases pressure.
