differential pressure transducers

Differential Pressure Transducers

Differential pressure transducers measure the difference in pressure between two points. Through various calculations, differential pressure transducers can also be used to monitor flow and density.

AST uses two sensor technologies for its differential products: MEMS strain gages and LVDT's. Our MEMS based AST5400 uses two independent pressure sensors to measure differential pressure where as the AST5100 and AST5300 utilize linear position sensors to monitor the deflection of the diaphragm. Below is a brief overview for each product.
