Renewed DPI differential pressure switch

The DPI differential pressure switch has been renewed. The new DPI-24 combines the advantages of an electronic differential pressure switch for air (on-off relay) and a multi-functional differential pressure transmitter.

These technologically advanced and versatile 24 Vac/Vdc differential pressure switches are available with one or two 24V relay outputs. The switch controls the relays based on either differential pressure or air flow.

In applications where the air flow signal is used to control the relays, a FloXact™ measurement probe can be used to measure the air volume flow in a ventilation duct or the flow rate on a centrifugal fan. The DPI-24 then calculates the flow and controls the relays based on these calculations.

The previously released DPI-24–BT models can be used with the MyTool® smartphone application and the MyTool Connect Dongle or via display menu (-D models).

Features:

• Differential pressure and flow transmitter/switch
• 3 different 8-range models: ±500, 2500, 7000Pa
• Manual zero point calibration
• Analog output signal: 1x 0…10 V, 1x 4…20 mA
• Span point calibration

Options:

• Display (-D models)
• Two relays (-2R models)
• Automatic zero point calibration (-AZ models)
• MyTool (-BT)

The previous version of DPI will be discontinued. The discontinued products can mostly be replaced with DPI-24.

The discontinued products will be available for sale until 30.6.2025 (or until stock lasts, whichever comes first) and deliveries will end on 31.12.2025 (or until stock lasts, whichever comes first). The last date of product support will be 31.12.2030.
