Dwyer Industrial Sensors

Dwyer industrial sensors provide reliable measurement of pressure, temperature, humidity, flow, air quality, level, and other conditions in your industrial process. They are known for their accuracy and consistent performance in HVAC, process automation, manufacturing, and environmental systems. These sensors withstand harsh environments and deliver repeatable readings that operators can depend on.

Dwyer designs housings, sensing elements, and internal electronics for rugged operation, even in dusty, humid, or high-vibration areas. Engineering expertise in robust sensor platforms means their products remain stable under heavy, continuous use. Dwyer’s instrumentation maintains accuracy over time, making it a go-to for utility plants, refineries, cleanrooms, and commercial buildings where reliability reduces downtime.

Dwyer offers sensors for differential pressure, static pressure, relative humidity, CO2 concentration, air velocity, liquid level, and more. Many of their sensors output analog signals or digital communication, simplifying integration to controllers, BAS systems, or SCADA. Field-selectable ranges and flexible sensor options make them compatible with many process requirements.
