Differential Pressure Measurement

ADTEK has multiple transmitters which can be applied on different types of work environment. To have a better quality of life, buildings with central centilation system (CVS) become a trend, so we recently developed a new product, DPA, indoor differential pressure transmitter. The users can set up the measured range according to the actual use, and make zero adjustment for the differential pressure. Besides being equipped with regular analog outputs, we also added RS-485 output to DPA which is a simple and low-cost communication tool connecting with monitoring system.

Features

■ Equipped with analog output or RS485 Modbus for analog input module and the communication for new systems.

■ Measurement range: lower range: 0 ～ ±50Pa; upper range: 0 ～ ±10,000Pa

■ Able to set the pressure range by setting the dip switches.

■ Models with analog output mode can distinguish three measurement ranges: -1000~+1000Pa / -10000~+10000Pa / -100~+100Pa range selection, each range can be switched between 3~4 measurement ranges.

■ Static accuracy: ±1.0%FS (normal temperature)

■ Equipped with temperature compensation ( -10~60℃ )

■ Various different pressure units. ˙ Able to go with/without display

■ Auto-zero point adjustment for pressure difference

■ Set the response time by setting the dip switches (0.5S~4S).

■ Separate installation of plastic board and the transmitter

Applications

■ HVAC system

■ central ventilation system (CVS)

■ Energy management system(EMS)

■ Variable Air Volume (VAV) System

■ Emission control system
