WinSMART LY50-A Hastelloy C-276 Absolute Pressure Transmitter 0.05% Accuracy HART 7 4-20mA

WinSMART LY50-A Absolute Pressure Transmitter with Evacuated Reference Cell

The WinSMART LY50-A measures absolute pressure against an evacuated reference cell, so barometric changes never bias the reading. The LY50 generation upgrades the diaphragm from 316L stainless steel to Hastelloy C-276 and tightens reference accuracy from ±0.075% to ±0.05% of span, which matters most at the low end of vacuum duty.

Upgraded Material and Higher Accuracy

Product Highlights

• Evacuated reference cell stays stable from 0–10 kPa abs to 0–10 MPa abs
• Hastelloy C-276 diaphragm resists solvents, acids and halogenated media
• ±0.05% of span accuracy with digital temperature and linearity compensation
• Overpressure protection up to 4x span on the low ranges
• 316L stainless steel housing with laser-engraved nameplate for full-life traceability

Technical Specifications

Typical Applications

• Vacuum distillation and evaporation units
• Cryogenic and liquefied gas storage
• Vacuum packaging and degassing lines
• Semiconductor and coating process chambers

Units are supplied with a vacuum-tightness test report and a calibration certificate listing the absolute reference value at five points. Stainless steel tag plates and Hastelloy capillary seals can be added on request.
