Features


Core Performance

· Anti-corrosion and anti-wear: The use of high-quality materials, such as 304 stainless steel for the housing and 316 stainless steel for the inner core, ensures the sensor can resist the effects of various corrosive media, extending its service life.

· Shock and vibration resistance: This feature allows the sensor to maintain stable performance even in harsh environments with frequent mechanical disturbances, ensuring accurate measurements at all times.

· Long-term stability and high accuracy: Boasting an accuracy of 0.5%F.S./1%FS (Typical) for linearity, hysteresis, and repeatability, the sensor provides consistent and reliable data over an extended period.


Technical Parameters

· Pressure Range: Available in 0-60bar/-1-700Bar, covering a wide spectrum of pressure measurement needs.

· Pressure Type: Supports Gauge Pressure, Absolute pressure, and Sealing pressure, offering versatility in different application scenarios.

· Output: Multiple output options are provided, including 4-20mA/0.5-4.5V/1-5V/0-10V/I2C, enabling seamless integration with various control systems.

· Power Supply: Compatible with 24VDC/12VDC/5VDC/3.3V, ensuring flexibility in power source selection.

· Temperature performance: The compensation temperature ranges from -20~85ºC, and the ambient and working temperatures can reach -40~125ºC. The temperature drift for zero and full range is ±0.15% F.S. (-20~85ºC), guaranteeing accurate measurements under varying temperature conditions.

· Connections: Electrical connections include Parkard, M12, DIN43650, and Cable outlet, while mechanical connections offer options like G1/4, 1/4NPT, 1/8NPT, M12*1.5, and customization, making installation convenient and adaptable to different setups.

· Protection: With an IP65 protection rating, the sensor is well-protected against dust and water, enhancing its reliability in challenging environments.
