Part numbers

From the manufacturer's datasheet for DPA+ RS485 BACnet differential pressure transmitter.

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. It has eight pressure ranges that can be selected at the device, so one unit covers several jobs in HVAC, clean rooms and process measurement. It uses a MEMS membrane element and reports over RS485 BACnet MS/TP, with 0 to 10 V or 0 to 5 V outputs. Versions are available in the 250, 2500 and 7000 Pa families, with or without an LCD with traffic light display, and as a Dual with two independent sensors in one housing. The mounting base is included and fits a flat surface or a TS35 DIN rail. Setup is by USEapp, uConfig, DIP switches or jumpers.
