Dual-Line Pulse Input Rate/Totaliser | PPM Series
Supplied by: Dwyer Instruments Aust.
The series PPM has a unique, rugged, NEMA 4X front panel design that makes it nearly impenetrable in typical applications.
The weatherproof, UV resistant, large, dual line display allows for more information, making it easier to read and simpler to program. The intensity of the display can be adjusted allowing this meter to be utilised in dark rooms as well as outdoors, due to its sunlight readable display. It features up to eight visual alarm set points to trigger certain events and three function keys which can be programmed to provide direct menu access. With up to four relays available, the PPM features latching, non-latching, sampling, pump alteration control, and a fail-safe action. Offering programmable delay time, this meter prevents recognition of false maximum or minimum reading which may be caused by the start-up or unusual process events.
The PPM provides three security passwords that restrict modification of programmed settings. This unit has the ability to obtain non-linear input signals and linearise them with a general purpose 32-point lineariser. Choose from RS-232, RS-422/485 serial communication options or any available expansion modules, accessories, and enclosures.
