Submersible Level Transmitters
Submersible level transmitters provide accurate and dependable measurement of the level of liquid in challenging environments such as tanks, wells, and sumps. They are often used in applications like monitoring groundwater, wastewater treatment, oil tanks, and industrial processes. These devices are equipped with submersible pressure sensors. They are used to measure liquid levels from the depths of difficult-to-access places. The transmitters detect pressure changes in the exceeded liquid from above the sensor. The precise level measurement can be used for monitoring equipment and liquid control.
Rugged construction and a long life are hallmarks of submersible level transmitters. They are made of stainless steel to withstand the most harsh applications and provide accurate level measurements in water, sludge, and slurry. Many models have a vented cable that equalizes the atmospheric pressure above the liquid surface. This not only makes the level measurement more accurate but also allows the cable length variations to place the transmitter at any desired depth in the liquid.

More Information about Submersible Level Transmitters
In hazardous locations, submersible level transmitters can be obtained with intrinsically safe approval. This ensures that they can operate safely in conditions where flammable gases or liquids may be present. These transmitters are highly accurate and very stable over the long term, making them essential for monitoring levels continuously in applications like oil storage, well water measurement, and tank monitoring. The small diameter and robust design of the transmitters means they can be used effectively in both confined and open spaces and that they are reliable with a very low maintenance need for measuring the levels of liquids.
FAQs
Are submersible pressure transducers and submersible pressure transmitters the same as submersible level transmitters?
Yes, submersible pressure transducers and submersible pressure transmitters are essentially the same as submersible level transmitters, as they all measure liquid levels by detecting pressure changes exerted by the liquid column above the sensor and converting it into an electrical signal for 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.
