Low Differential Pressure Transducers/Transmitters
Alpha low pressure differential pressure transducers & transmitters sensors are constructed by stainless steeland glass, no glue or other organics. That provides excellent performance, corrosion resistance and long-term stability.
Our low pressure transmitters/transducers cover 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 measurement.
Alpha has the product to meet a breadth of HVAC,critical environments,animal husbandry,textile industry applications and can be trusted in your most critical applications.
