The Model 172M from SENBA is a high-precision low differential pressure transducer designed for accurate measurement of air and other non-conductive gases. It is widely used in HVAC systems, industrial automation, and environmental monitoring applications requiring stable and reliable low-pressure sensing performance.
This sensor supports both unidirectional (25Pa to 25,000Pa) and bidirectional (±10Pa to ±10,000Pa) measurement ranges, providing flexible integration across various pressure monitoring systems. It offers selectable accuracy levels of ±1.0%, ±0.4%, and ±0.25% (RSS at constant temperature), ensuring precise performance based on application requirements.
The Model 172M provides a standard 4–20mA output signal, enabling seamless integration with PLCs, industrial controllers, and automation systems. It also features robust overload protection, capable of withstanding up to 100kPa pressure in both positive and negative directions without damage, ensuring high durability and operational safety.
With stable performance and high sensitivity, the Model 172M is ideal for demanding environments requiring accurate differential pressure measurement.
