The Model 178 from SENBA is a high-precision low differential pressure transducer designed for accurate measurement of air and other non-conductive gases. It delivers stable, reliable performance for industrial, HVAC, and environmental monitoring applications where precise low-pressure detection is required.
This transducer supports a wide measuring range, including unidirectional pressure from 25Pa to 25,000Pa and bidirectional pressure from ±10Pa to ±10,000Pa. It offers multiple accuracy grades of ±0.8%, ±0.4%, and ±0.25% (RSS at constant temperature), allowing flexible selection based on application precision requirements.
The Model 178 provides a standard 4–20mA output signal, ensuring easy integration with PLC systems, industrial controllers, and automation equipment. It also features strong overload protection up to 15 PSI (100 kPa) in both forward and reverse directions, enhancing safety and durability in demanding operating conditions.
With its high stability, low-pressure sensitivity, and robust design, the Model 178 is well-suited for critical airflow and differential pressure monitoring systems.
