Product Features
Wide temperature adaptability: The working temperature range covers 0 to 50℃, capable of handling common temperature changes such as day-night temperature differences in workshops and equipment heat dissipation. No additional temperature control devices are required, making it suitable for most industrial scenarios.
Strong anti-interference ability: Insulation resistance ≥50MΩ. When away from interference sources such as frequency converters, it can stably read pressure data, avoiding reading fluctuations caused by electromagnetic interference and ensuring its use in precision scenarios (such as semiconductor manufacturing).
Protection and durability: IP40 protection rating, effectively preventing dust from entering and reducing component wear and tear; The shock-resistant and vibration-resistant design makes it less likely to malfunction even when installed in vibrating environments such as beside machine tools, reducing maintenance frequency.
Multi-scenario compatibility: Supports vacuum (0 to -101.0kPa), mixed pressure (-100 to 100kPa) and other ranges, suitable for vacuum adsorption, air source monitoring and other scenarios; With flexible installation methods (M5/1/8 thread, quick-change couplings), it can meet the needs of narrow Spaces or different installation requirements.
Safety and Compliance: Complies with CE, UL/CSA, and RoHS certifications. It can be used with confidence in industries with high compliance requirements such as electronics and automobiles, without worrying about compliance risks.
