Festo offers a variety of pneumatically and electrically actuated visual indicators:
Vacuum Gauge
Type VAM-... ..................................................... 249
The pneumatic indicators include in-line and panel
mounted designs as well as a multi-pin indicator, all
of which simplify monitoring of pneumatic control
system operating conditions.
Festo also offers a range of LED indicator solenoid
inserts and gaskets that can be easily installed on
solenoid actuated valves to provide ON status indication and simplify troubleshooting.
For applications requiring gauges, conventional
threaded connector designs as well as panel
mounted versions are available, with pressure
ranges from 0 to 240 psi. Vacuum gauges with
ranges from 29.6 in HG to 131 psi are also available.
