PDT101
Differential pressure transmitter for critical environments
An air differential pressure transmitter with high-accuracy bidirectional models for cleanrooms and regulated environments, and unidirectional models for air handling systems. The micro-machined silicon diaphragm sensor provides inherent repeatability and stability, with calibrations traceable to SI units.
