Dwyer Level Switches
Dwyer level switches are widely known for providing simple, durable, and reliable level measurements for liquids in industrial systems, process tanks, and sophisticated equipment all over the world. They are level-measuring devices you can control and depend on. There is a good reason why so many professionals and organizations trust the basic level measurement actuation and "on/off" control provided by Dwyer float-style switches.
Level-measuring devices must first and foremost be able to perform under the conditions they face. In industrial settings, we are usually dealing with conditions that are well-defined, controlled, and consistent across a certain range of temperature, pressure, and liquid type (e.g., water, oil, or some other chemical). Switches must also tolerate, if not thrive, in the presence of certain common harsh conditions: corrosive materials, vapors, and liquids; high-pressure air; vibration; and temperature changes that can be pretty extreme in some contexts.
Dwyer level switches incorporate very simple wiring, standard connections, and versatile mounting to accommodate both new and existing installations. They can be used with great ease and great flexibility in a number of ways. For instance, they can be wired to integrate directly with the basic elements of a system, such as pumps and alarms, for a range of plumbing layouts that convey fluids. They can likewise work with PLCs and building management systems to incorporate level control and protection in fluid-handling systems throughout a facility.
FAQs
What are Dwyer level switches used for?
Dwyer level switches monitor liquid levels in tanks, sumps, and process systems to control pumps, alarms, and automated equipment.
What types of level switches does Dwyer offer?
They offer float, ultrasonic, capacitance, optical, and solid-state level switches for a wide range of fluids and environments.
Can Dwyer level switches handle chemicals or corrosive liquids?
Certain models are specifically designed for chemical compatibility and are widely used in industrial and wastewater applications.
Do Dwyer switches work with PLCs?
Yes, Dwyer level switches offer standard electrical outputs compatible with PLCs, pump relays, control panels, and automation systems.
Can Dwyer level switches be used in clean-water applications?
Yes, they’re commonly used for potable water, HVAC tanks, and general-purpose level monitoring.
Transmitters vs Transducers
Some of the most common types of transmitters and transducers can be found on pressure instruments. Examples of these include: drop-in well pressure devices and devices that measure the pressure in a pipe or gas chamber. Transmitters and transducers can also be found on flow and speed measurement devices.
What is the difference between transmitters and transducers?
The main difference is the way they send data to the monitoring device, like a PLC. In terms of measurement, the transmitter will reference a measuring unit by sending a milliamp signal (such as 4-20 mA). A transducer will reference a measuring unit by sending a voltage signal, typically in volts or millivolts.
Why have the two different types of transmission methods?
The method will depend on the application. If the electrical connection in the application travels a short distance, a pressure transducer is the better choice. Pressure transducers are smaller with fewer active electronic components that can be upset by electromagnetic interference. Also, the voltage signals transmitted over longer distances are subject to voltage drop and signal corruption. A transmitter is better for transmitting signals over a long distance.
