The PCL41 Series pressure
standard incorporates features
found in high-end standards into an
affordable, portable benchtop unit.
The microprocessor-based
controller allows the user to adjust
display filtering and resolution for
the particular application. The frontpanel tare allows zeroing of the
display with the push of a button.
With the display hold feature, the
user can test pressure switches. An
external connection is completed
when the pressure switch under test
changes state. The switch freezes
the display, which shows the true
actuating pressure.
Other available options include
scalable analog outputs, RS232
or RS485 communications,
and mechanical relays. With
the right combination of options,
the PCL41 can become a
sophisticated data system.
