Gage and Absolute Pressure Transmitters [ALAPT/ALGPT]
ALAPT/ALGPT Pressure Transmitters that combine proven capacitive sensor measuring techniques with advanced microprocessor technology
The ALDPT-3051 GP and AP are intelligent differential pressure transmitters that combine proven capacitive sensor measuring techniques (piezoresistive sensors for absolute pressure models) with advanced microprocessor technology. By making use of advanced microprocessor technology, the ALPDT-3051 is able to offer features that include self-diagnostics, field parameter adjustment, auto-zeroing, and digital communication capabilities; at significantly lower prices versus competitive models.
The ALDPT-3051 smart pressure transmitter is offered with a wide array of threaded and
flanged process connections and may also be equipped with optional valve manifolds. Available output options include 4-20mA or 1-5VDC with HART protocol, Profibus, or Foundation Fieldbus. The versatility and wide array of options offered by the ALPDT-3051 smart pressure transmitter make it suitable for almost any application.
