Visual Indicator
The PureForce visual indicator is self-housed and features a pop-out
button, which is triggered via magnetic force. Once triggered, the PureForce
indicator stays activated even when the hydraulic system is shut down.
Electrical Indicators
Baldwin’s electrical indicators are available in three styles — single-post,
2-wire and 3-wire. The PureForce electrical indicators are also self-housed
units that do not rely on base geometry for proper activation.
Single-Post Indicator
Designed for mobile applications with
DC voltage, the single-post indicator is compact in design and can be
used when the filter base is grounded. Unlike the other PureForce indicators,
the single-post indicator does not utilize magnetic force to activate
the switch. Instead, the single-post design utilizes piston travel to
ground the post to the switch housing.
2-Wire Indicator
Also intended for DC voltage
applications, the 2-wire indicator can be used in applications where
the housing is
not grounded. The 2-wire indicator utilizes a magnet which interacts
with a reed switch through the walls of the indicator housing to provide
clean
on/off switching.
3-Wire Indicator
For use in AC or DC voltage
applications, the 3-wire electrical indicator is the ideal choice where
3-wire logic
is being used. This versatile indicator is micro-switch activated and
is rated at 2 amps. A threaded female conduit connection allows for the
use of conduit to protect the wires.
