Submersible Level Transmitters
Submersible level transmitters are designed for accurate and reliable liquid level measurement in applications where the sensor must be fully immersed. Commonly used in water tanks, oil tanks, wells, pits, and wastewater systems, these devices are built to withstand continuous exposure to liquids and harsh environmental conditions. Their robust construction allows for dependable performance in industrial, municipal, and hazardous environments where consistent level monitoring is critical.
These transmitters operate by measuring the hydrostatic pressure exerted by the liquid column above the sensor. The pressure reading is converted into an output signal, typically a 4–20 mA signal, which corresponds directly to the liquid level. Submersible level transmitters integrate easily with PLCs, control panels, and monitoring systems, making them suitable for continuous level measurement and control applications.
Submersible level transmitters are valued for their accuracy, long-term stability, and cost-effective design. Many models are available with mounting accessories such as brackets and hangers that allow the sensor cable to be suspended securely at the desired depth. Intrinsically safe options are also available for hazardous locations, ensuring safe operation in environments where flammable gases or liquids may be present. Their compact size and low maintenance requirements make them effective for both confined spaces and open installations.
FAQs
Q: What are submersible level transmitters used for?
Submersible level transmitters are used to continuously measure liquid levels in applications such as wells, tanks, sumps, pits, and wastewater systems by sensing hydrostatic pressure.
Q: Are submersible pressure transducers the same as submersible level transmitters?
Yes, submersible pressure transducers and submersible pressure transmitters are commonly referred to as submersible level transmitters. They all measure liquid level by detecting pressure changes caused by the height of the liquid column.
Q: Can submersible level transmitters be used in hazardous locations?
Yes, many submersible level transmitters are available with intrinsically safe approvals, allowing them to operate safely in hazardous environments where flammable substances may be present.
Q: How do submersible level transmitters connect to control systems?
They typically connect using industry-standard output signals such as 4–20 mA, allowing direct integration with PLCs, SCADA systems, and other monitoring equipment.
Q: What is the difference between a transmitter and a transducer?
A transmitter sends a standardized current signal, such as 4–20 mA, which is well-suited for long-distance signal transmission. A transducer typically sends a voltage signal and is better suited for shorter distances with minimal electrical interference.
