Part numbers

From the manufacturer's datasheet for DPA+ LoRaWAN.

Overview

The DPA+ measures overpressure, underpressure, differential pressure and volume flow of air and other non-aggressive gases in fan and filter systems and ducts. Each version has eight selectable pressure ranges, and flow can be shown in m3/h or cfm and pressure in Pa or inch water column. It reports over LoRaWAN at 868 MHz and also has two 0 to 10 V or 0 to 5 V analogue outputs. The Dual version has two independent sensors in one enclosure for up to two differential pressures or two flow volumes. An optional external antenna helps in radio shielded locations. A mounting base is included for flat surface or TS35 DIN rail mounting, together with a pressure connection set and 2 m of PVC hose.
