501A Series

The 501A Series are small, light-weight, high-frequency transducers designed to measure liquid and gas differential pressures from 1 to 1000 psi (70 mbar to 70 bar).

The reference port is the dry port.  The standard wet/dry transducer is supplied with no line pressure, but models are available on request for operation with line pressure and overload capabilities.  (Optional line pressure and mechanical stops are available for wet port only of 10 times full scale range or 1000 psi, whichever is less.  Contact the factory for details.)

Stainless-steel construction provides exceptional durability in harsh industrial environments.

General Specifications are given below.
