FAQ
2cp5 Pressure Transducer
How does the ceramic capacitive technology benefit industrial pressure measurement?
A: Ceramic capacitive technology enables direct pressure measurement (no intermediate fluid), excellent long-term stability, and compatibility with harsh environments — reducing maintenance and extending service life.
What supply voltage/output signal does the 2cp5 Series use, and is it compatible with industrial control systems?
A: It uses a 4.5V-5.5V DC supply voltage and 0.5V-4.5V DC (typical) output signal — compatible with most standard industrial control systems (e.g., PLCs, data loggers).
What is the standard pressure range of the 2cp5 Series, and does it cover typical industrial system pressures?
A: Its standard pressure range spans 0-15 psi ~ 0-750 psi (or 0-1 bar ~ 0-50 bar), which aligns with most common industrial pressure measurement needs.
What pressure port and connection materials are available, and do they match standard industrial fittings?
A: The pressure port is 1/4″ SAE female flare (with deflator) + 7/16″-20 UNF-2B. Connection materials include brass (2CP5-exclusive) or plated steel — aligned with common industrial fitting standards.
