Dwyer Pressure Sensors-Transmitters
For precise and stable pressure measurements in HVAC systems, as well as in industrial automation, process control, and building monitoring, Dwyer pressure sensors and transmitters have a well-earned reputation. They are superior in both design engineering and reliable performance. Dwyer builds pressure sensors and transmitters to deliver clean and reliable electrical pressure signals that help to indicate the state of airflow; duct static pressure; liquid systems; and the working state of various pneumatic controls. Their product line spans the range from an essentially low-pressure air sensor used to control airflow in a cleanroom application to a boxy, robust, industrial-grade pressure transmitter built to measure liquid pressure in a harsh environment.
Of the several strengths that Dwyer pressure sensors and transmitters have, the most important one is probably the wide diversity of sensor models built for different applications. Dwyer offers differential pressure sensors built for work with airflow, filter monitoring, and room-pressure control, along with gauge models built for water and gas systems, and other pressure and compound gauge models built for general use in industrial applications. Dwyer is the brand of choice for HVAC and industrial contractors when it comes to selecting reliable pressure sensors and transmitters for their many, many installations.
FAQs
What are Dwyer pressure sensors and transmitters used for?
Dwyer pressure sensors and transmitters measure air, gas, and liquid pressure in HVAC systems, building automation, industrial equipment, and process controls.
Are Dwyer pressure transmitters accurate and reliable?
Yes, Dwyer transmitters are designed for stable, long-term accuracy with minimal drift, even in high-vibration or harsh operating environments.
What types of pressure sensors does Dwyer offer?
Dwyer offers differential, gauge, and compound pressure sensors, including models for low-pressure airflow, duct static pressure, and liquid systems.
Do Dwyer transmitters support standard output signals?
Most models provide 4–20 mA, 0–5V, or 0–10V outputs compatible with PLCs, building automation systems, and remote monitoring platforms.
Can Dwyer pressure sensors handle demanding conditions?
Yes, many sensors include stainless-steel wetted parts, sealed housings, and rugged electronics designed for moisture, vibration, temperature swings, and industrial contaminants.
Instrumentation: Elements & Transmitters
2 pieces of hardware used in modern day instrumentation: measuring elements and transmitters.
Measuring Elements
Measuring elements are the part of the device that performs the measurement. For example, the measuring element of a pressure transducer is the part that is actually lowered into a tank that will take a pressure measurement. The measuring element of a flow meter is the part that actually measures the flow and an RTD or thermocouple takes the temperature measurement.
Transmitters
Transmitters collect information from measuring elements and sends the information to where it is needed. The transmitter interfaces with the measuring element and interprets the information. It then sends that information to a PLC, RTU or some other type of control unit. In many cases, the transmitter has the ability to communicate the information via multiple communication protocols. This may be necessary when the measuring element does not send the same type of signal that is needed by the controller. For example, it may be necessary to convert a temperature reading from a thermocouple to a 420 milliamp signal that can be received by a local PLC.
