The YE series is a line of capsule pressure gauges designed for measuring very low positive and negative pressures (micro-pressure / vacuum) of gases that are non-corrosive to copper alloys and non-explosive. Its sensing element is a corrugated metallic capsule — two thin diaphragms sealed together — which expands and contracts with extraordinary sensitivity to minute pressure changes, where a standard Bourdon tube cannot deliver a reliable reading.

Key features:

• Capsule sensing element — high sensitivity for micro pressures from as low as ~1 mbar up to 60 kPa, with clear full-scale dial deflection

• Wide range options: positive 0~1.6 to 0~40 kPa; negative -1.6~0 to -40~0 kPa; compound ranges (±0.8, ±1.2, ±2, ±3, ±5, ±8, ±12, ±20 kPa)

• Dual-scale dials available: kPa / mmH₂O / mbar / PSI

• Dial sizes: 60 mm, 75 mm, 100 mm, 150 mm (YE-60 / YE-75 / YE-100 / YE-150)

• Accuracy class 2.5 (Class 1.6 on request); zero-adjustment device included

• Construction options: chrome-plated steel case with brass connection, or full stainless steel versions (YE-B / YE-BF series) for corrosive environments

• Gas media only — suitable for dry, clean air and gases; not for liquids or strong corrosive media

• Working temperature -20 ~ +60 °C; overpressure capacity 130% of full scale

Typical applications: boiler ventilation and draft monitoring, gas pipelines, combustion and burner systems, HVAC duct pressure, dust-collection and furnace negative-pressure monitoring, biogas and gas supply systems.上海自动化仪表有限公司Hongqi InstrumentGiantWellWUXI CITY HUIHUA SPECIAL INSTRUMENT CO.,LTD.wuxigauge.en.made-in-china.com
