Alpha low differential pressure transmitter, low differential pressure sensor, low differential pressure transducer,is constructed by stainless steeland glass, no glue or other organics. That provides excellent performance, corrosion resistance and long-term stability.

Our low pressure differential pressure transducer covers the pressure range of 0.1 inch H2O to 100 inch H2O, or 25 Pa to 25000 Pa. With our unique manufacturing techniques, we can readily produce transducers sensors with custom pressure ranges and make use of them in very low pressure measurement or ultra low differential pressure sensor.

As the pressure transmitter manufacturer, Alpha has the product to meet a breadth of HVAC applications and can be trusted in your most critical applications.

The Model 161 differential pressure transducer provide excellent sensitivity and long term stability, assuring precise measurement and control at extremely low differential pressures.
