SmartMeasurement’s ALDP-3051 is an intelligent differential pressure transmitter which makes use of advanced microprocessor technology with digital communications. The ALPD-3051 smart pressure transmitter is capable of differential, gage, or absolute pressure measurement. It uses advanced capacitive sensor technology (piezoresistive sensors for absolute pressure models), and features self-diagnostic, field parameter adjustment, auto-zeroing and a variety of popularly used communication protocols at industry leading prices. The ALDP-3051 smart pressure transmitter can utilize either traditional flanges or any other industry standard process connection for pressure, flow and level applications. Available outputs include 4-20mA or 1-5VDC with HART protocol, Profibus, or FOUNDATION fieldbus. The ALPD-3051 smart pressure transmitter is available in a wide variety of configurations to make it suitable for almost any application.
