Level sensors detect liquid or powder levels and interfaces between them. They are an essential part of fluid systems and have a variety of applications, including overfill shutoff, leak detection, and liquid inventory management.
Different measurement technologies, such as guided wave radar, differential pressure, and capacitance, are available. The right technology will depend on the media type and the application.
Ensure the Transmitter is Fully Charged
Many different types of level sensors can be used in various applications. These include high or low-level sensing and alarms, leak detection, overfill shutoff, regulating the interface between levels of different media, and more.
A wide range of output options are also available for each sensor type. For example, continuous-level sensors can produce 4-20 mA current, and HART signals that directly correlate to the fluid level in the tank. Conversely, point-level sensors indicate whether the liquid or dry material is above or below a specified point value.
It is essential to ensure the transmitter is fully charged before using it. This can be done by connecting the charger to the receiver and plugging it into a power source. The indicator lights on the transmitter and receiver should start flashing green when fully charged. It is also essential to keep the transmitter and receiver away from external heat sources and operate them at reasonable temperatures.
Connect the Transmitter to a Power Source
Wema Kus level senders detect the levels of liquids, powders, or interfaces between different media. They are found in various industries, including but not limited to manufacturing, food and beverage, pharmaceutical, marine, and energy management.
Depending on the application, you may need a point-level sensor that marks a specific level and communicates whether the media is above or below it or a continuous-level transmitter that measures and displays a continuous value. Some models also come with a display and user interface to help you make your process more efficient.
Connecting a transmitter to a power source is simple. Just plug the 0V and 4-20mA signal lines into a power supply. You will want to turn on and link each transmitter/receiver pair individually to avoid cross-linking and ensure your system operates correctly. Once the blue RF LED illuminates, you know your transmitter and receiver are linked.
Make Sure the Transmitter is Powered Up
Level sensors are used to measure a variety of different media in several various applications. Some are simple gauges that use a single electrode to determine the level of the press. In contrast, others offer more advanced features, such as a local programmable display or controller/totalizer.
For a transmitter to work, it must be adequately powered up and connected to the system. To check the power supply of a transmitter, use a multimeter to measure the voltage between the positive and negative outputs of the device. The voltage should be within the range specified by the manufacturer.
The transmitter may have been wired incorrectly if the voltage is outside this range. This could be caused by a wiring error or a problem with the sensor itself. If this is the case, a replacement transmitter should be installed. To check the wiring, consult the product label or instruction manual for instructions on how to do so.
Connect the Transmitter to a Computer
Level sensors measure the position and displacement of a liquid, powder, or bulk solid in a container. They can also be used to detect interfaces between different fluids. There are two main types of level measurement: point level and continuous level.
Point-level sensors detect a specific point in the media and communicate whether it is above or below. They are generally used as high alarms or switches but can be integrated into a continuous-level sensor to add a low alarm function.
Continuous level sensors continuously monitor a range of levels in the media and produce an analog output that correlates with the measured. They are more sophisticated than point-level sensors and can be used to provide a complete fluid system solution. It can be connected to various display and user interfaces, including simple gauges, locally-programmable units, and controller/totalizers. They can also be connected to a computer for use with process control systems. Read more interesting articles on Ebeak
