The DPI-24 differential pressure switch is a versatile 24V AC/DC differential pressure indicator that combines the advantages of an electronic differential pressure switch for air and a multifunctional differential pressure transmitter. It also includes a flow switch.

These technologically advanced and versatile differential pressure switches are commonly used in HVAC/R systems for monitoring fans, blowers, and filters; stairwell pressure monitoring and alarming; cleanroom pressure monitoring; and boiler pressure monitoring and alarming.

The DPI-24 provides eight pressure measurement ranges in each model. It supports five pressure measurement units and six flow measurement units.

It features a reach point adjustment function for cleanroom and other high-precision applications that require annual calibration of the differential pressure switches.

This model has a relay output. The switch can control the relay based on either differential pressure or air flow rate. The relay's operating direction, switching point, and hysteresis are configurable.

This model automatically adjusts the zero point and does not require manual zeroing.

The display shows the measured pressure or flow rate and the relay status.

It supports the MyTool Connect dongle and the MyTool® smartphone app for configuring settings.
