Senva’s PW31 Series is designed to streamline installation and provide maximum accuracy. Options for standalone transducer or 3-valve and 5-valve bypass assemblies allow flexibility and save time on installation and commissioning. The single-diaphragm element is temperature compensated to provides superior ±0.25% accuracy.
The single-diaphragm silicon piezoresistive differential pressure element is engineered to measure only the differential pressure, so is not affected by high gauge pressures.
It’s compact, light, and rugged structure combined with IP65 stainless steel construction make it ideal for most installations and capable of withstanding the most rugged environments.
