Product Overview
Schneider A-201 Pressure Gauge
The Schneider Electric 2420-001 Pressure Gauge is a stem-mounted gauge used to continuously indicate air pressure in pneumatic HVAC control systems. It has a 1-1/2-inch dial, a 0 to 30 psig range, and a 1/8-inch MNPT center-back connection for monitoring main-air pressure or pneumatic-control output pressure. Manufacturer documentation identifies 2420-001 as the replacement for legacy A201 and AL-362 gauges.

FAQs:
Q: What replaces the Schneider A201 pressure gauge?
A: The manufacturer-documented replacement for the legacy A201 pressure gauge is part number 2420-001. The same model chart also identifies 2420-001 as the replacement for AL-362, but the pressure range, mounting arrangement, dial size, and connection should be checked before ordering.
Q: What are the specifications of the Schneider 2420-001 pressure gauge?
A: The 2420-001 has a 0 to 30 psig, or 0 to 200 kPa, pressure range, a 1-1/2-inch dial, stem mounting, and a 1/8-inch MNPT center-back air connection. Its construction includes an ABS plastic case and friction ring, with a phosphor-bronze Bourdon tube and brass gearing.
Q: What is the Schneider 2420-001 pressure gauge used for?
A: The 2420-001 is used for continuous indication of air pressure in pneumatic control systems. Its 0 to 30 psig range supports readout of main-air pressure and output pressure from pneumatic control components.
Q: How can I confirm that the 2420-001 will replace my A201 gauge?
A: Confirm that the existing gauge is marked A201 or AL-362 and that the application requires a 0 to 30 psig range, 1-1/2-inch dial, stem mounting, and 1/8-inch MNPT center-back connection. These details help distinguish the 2420-001 from other gauges with different configurations.
Q: Is the Schneider 2420-001 the same as other 2420 Series pressure gauges?
A: No. The 2420-001 is specifically the 1-1/2-inch, 0 to 30 psig, stem-mounted model with a 1/8-inch MNPT center-back connection. Other 2420 Series models have different dial sizes, connection positions, pressure ranges, or mounting arrangements, so the complete part number should be verified before purchase.
