Dwyer Instruments
Dwyer Instruments is a globally recognized manufacturer of innovative sensors, controls, and instrumentation for the HVAC, industrial, and environmental markets. Dwyer’s extensive product range includes differential pressure gauges, pressure and temperature sensors, air velocity transmitters, flow meters, humidity monitors, and manometers—all essential for accurate system monitoring, energy efficiency, and regulatory compliance. Their instruments are widely used in applications such as air balancing, cleanroom control, duct static pressure monitoring, building automation, and indoor air quality systems. In addition to complete instruments, Dwyer manufactures compatible accessories and replacement parts, including diaphragms, pitot tubes, fittings, valves, and mounting hardware. Their products are known for their durability, precision, and ease of installation.
At PartsHnC, we offer a wide range of Dwyer Instruments parts, including 1/4" brass pressure snubbers, 1.0A solid core current switches, outdoor static pressure sensors, process controllers (100-240V), and Water Leak Detectors. Our inventory also includes air flow paddle switches, differential pressure controllers, flow indicator double windows (3/4" NPT), digital pressure gauges, plastic manometers (0/3" WC), and more.
FAQs
How does a Dwyer pressure switch work?
It activates or deactivates a circuit based on preset pressure levels, protecting systems from overpressure or underpressure.
What’s the difference between a Dwyer pressure transducer and transmitter?
A transducer outputs millivolt signals; a transmitter outputs amplified signals (e.g., 4–20 mA) for longer-distance accuracy.
When should I replace a Dwyer pressure gauge?
Replace if readings drift, the needle sticks, or it fails calibration — typically every 1–2 years in critical applications.
What causes failure in Dwyer flow switches?
Build-up, corrosion, or mechanical fatigue over time; regular maintenance and system cleanliness help prevent issues.
