Commonly Used Accesories

Transmitter Output

A 4-20mA/0-10 Volt transmitter can be installed on the DPP975 filter indicator, making it one of the lowest cost means of remotely monitoring any filter system

Mounting Base

All filter indicators are designed to directly connect into a filter head, however we also offer mounting bases with 1/8″ NPT connections to pipe to.

Mounting Brackets

Pipe or wall mounting brackets that work with mounting bases to easily install into systems.

Electrical Switches

1 or 2 SPST or SPDT switches that can be set and field adjusted to the pressure range.

Bolt On Filter Indicators

These filter indicators use a 1.75″ bolt pattern to directly mount into your filter head. A mounting base can also be used to connect to 1/8″NPT connections
