Core Application & Target User Overview
This guide covers professional pressure gauges of YTP, YE, and YP series, compatible with industrial equipment and systems including chemical reactors, oil & gas pipelines, water treatment facilities, and hydraulic/pneumatic systems in manufacturing plants. Tailored for process engineers, plant maintenance teams, chemical processing enterprises, and oilfield service companies, it addresses the critical demand for high-precision, corrosion-resistant, and stable pressure measurement tools to avoid production accidents, quality defects, or equipment damage caused by inaccurate pressure monitoring. All products comply with EN 837-1 (pressure gauge standards), ISO 9001 (quality management system), and IP65 protection rating requirements, undergoing rigorous accuracy calibration and environmental adaptability testing to ensure reliable performance in harsh industrial environments (corrosive media, vibration, and extreme temperatures).
YTP Series Diaphragm Corrosion-Proof Pressure Gauges
YTP Series Diaphragm Corrosion-Proof Pressure Gauges are specialized for measuring pressure of corrosive, viscous, or solid-containing media (e.g., acid, alkali, slurry) in chemical, pharmaceutical, and wastewater treatment industries. Their diaphragm-sealed structure prevents media from entering the gauge core, avoiding core corrosion and jamming. Premature failure (diaphragm damage, accuracy drift) can lead to misjudgment of process pressure, causing material waste or equipment corrosion. Our YTP gauges adopt high-quality corrosion-resistant materials and precision diaphragm sensors, ensuring long-term stable measurement with accuracy class up to 1.0.
Field Application Case
A chemical plant in Jiangsu encountered frequent corrosion failures of ordinary pressure gauges in their sulfuric acid storage tank pressure monitoring system, leading to 3 unplanned shutdowns annually. After replacing with YTP-100F corrosion-proof pressure gauges (complying with EN 837-1), the gauges maintained stable performance for 12 months without corrosion. The accurate pressure monitoring reduced sulfuric acid waste by 15% and eliminated shutdown losses caused by gauge failure.

YE Series Bellows Pressure Gauges
YE Series Bellows Pressure Gauges are designed for measuring low-pressure gas or liquid media (e.g., natural gas pipelines, ventilation systems) in oil & gas, HVAC, and food processing industries. The bellows sensing element provides high sensitivity to low pressure changes, ensuring accurate measurement of micro-pressure. Premature failure (bellows fatigue, zero drift) can lead to inaccurate pressure control, causing gas leakage or product quality issues. Our YE gauges adopt precision stainless steel bellows and stable movement structures, with accuracy class up to 1.5, suitable for long-term low-pressure monitoring.
