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.
