The Model 178A from SENBA is a high-precision low differential pressure transducer designed for accurate measurement of air and other non-conductive gases. It delivers stable and reliable performance for HVAC, industrial, and environmental monitoring systems requiring precise low-pressure detection.
This transducer supports a wide measurement range, including unidirectional pressure from 25Pa to 25,000Pa and bidirectional pressure from ±10Pa to ±10,000Pa, providing flexible integration across various applications. It offers multiple accuracy grades of ±0.8%, ±0.4%, and ±0.25% (RSS at constant temperature), ensuring selectable precision based on system requirements.
The Model 178A features a standard 4–20mA analog output signal, enabling easy integration with PLCs, control systems, and industrial automation equipment. It also includes robust overload protection up to 15 PSI (100 kPa) in both forward and reverse directions, ensuring safe operation under high-pressure conditions.
With its high stability, low-pressure sensitivity, and reliable performance, the Model 178A is ideal for demanding applications requiring accurate differential pressure measurement.
