The PDD series digital pressure switch integrates the latest solid state sensing technology into a very versatile, simple to operate package. Programming features include set point, reset point, window mode, pulsation dampening, switch logic, and user settable lockout code. The ceramic sensing system and solid state transistor switch ensure an exceptionally long cycle life with virtually no calibration drift. These features along with the compact, robust stainless steel housing make the PDD an ideal choice for OEM applications.
