1. Description
The 2450 Pressure Sensor has a one-piece injection molded PVDF body and ceramic diaphragm for superior compatibility in corrosive
liquids. These sensors are available with Digital (S
ranges for optimal measurement resolution. Built-in temperature compensation provides outstanding accuracy over a wide operating
range. Versions with / in. union process connection are best suited for in-line installations.
