Frequently Asked Questions

Why are Dwyer Magnehelic differential pressure gauges industry standard for HVAC systems?
The Dwyer Magnehelic gauge employs a frictionless magnetic movement that eliminates wear, hysteresis, and mechanical fatigue, making it exceptionally reliable for low-pressure gas applications. Its rapid response and high accuracy are crucial for monitoring clean room pressures and filter conditions in critical HVAC infrastructure.
Are Dwyer pressure transmitters certified for use in intrinsically safe environments?
Dwyer offers specific series of pressure transmitters that carry intrinsic safety approvals, such as ATEX and FM certifications, for use in hazardous locations. Engineers must specify the appropriate approved models and ensure they are installed with compatible intrinsically safe barriers.
What types of flow sensors does Dwyer provide for industrial liquid processing?
Dwyer manufactures a comprehensive portfolio of liquid flow sensors, including paddlewheel, electromagnetic, and ultrasonic technologies. These sensors are designed to accommodate varying fluid viscosities and conductivities, providing versatile solutions for process cooling, wastewater, and chemical dosing systems.
How do Dwyer level switches perform under turbulent fluid conditions?
Dwyer designs robust float and tuning fork level switches that incorporate specific damping mechanisms to mitigate the effects of surface turbulence. For highly agitated tanks, we often recommend their capacitive or ultrasonic level transmitters to provide stable, non-contact continuous measurement.
Can Dwyer temperature controllers handle multi-zone heating processes?
Yes, Dwyer provides advanced microprocessor-based temperature controllers capable of managing multiple heating and cooling zones simultaneously. They feature advanced PID auto-tuning algorithms that ensure precise thermal regulation, minimizing overshoot and optimizing energy consumption in complex thermal processes.
