Siemens offers a wide range of industrial level sensors designed to monitor liquid levels in various industrial applications. These devices can be used to control pumps, valves, and other devices depending on the liquid level in reservoirs, tanks, or wells. Today, we will look at Siemens level switches in more detail.
Explore the Range of Siemens Level Switches
If you decide to choose a Siemens level switch, you should be prepared that the choice will not be straightforward, given the wide range of products. Let's find out exactly what devices the company offers.
Float level switches
Siemens manufactures float level switches that use the buoyancy principle. These switches are typically used in applications where liquid levels must be monitored or controlled. Depending on the specific application requirements, they can be installed vertically or horizontally.
Capacitive level sensors
Capacitive level sensors from Siemens are designed to detect the presence or absence of liquid or solid material. They work based on a change in capacitance between the sensor and the target substance. These switches are often used in applications where contact with the material is undesirable or impossible.
Ultrasonic level sensors
Siemens ultrasonic level switch uses ultrasonic technology to detect the level of liquid or solid materials in a container. They emit ultrasonic pulses and measure the time it takes for them to be reflected to the sensor. These switches are suitable for various applications and provide non-contact level measurement.
Vibrating level switches
Vibrating level switches work by detecting changes in vibration frequency caused by the presence or absence of material. Siemens offers vibrating level sensors suitable for both liquids and solids. They are often used when the measured material is sticky, viscous, or prone to deposits.
Guided wave radar level sensors
Siemens Guided Wave Radar Level Sensors use radar technology to measure the level of liquids, solids, and interface layers. They emit radar pulses along a probe or cable, and the reflected signals are analyzed to determine the level of the material. These switches suit demanding applications such as high temperatures, pressures, or aggressive environments.
Hydrostatic level sensors
Siemens hydrostatic level sensors use hydrostatic pressure to detect liquid levels. They are often used in applications where the process pressure is constant and the fluid's specific gravity is known. These switches are simple in design and provide reliable level detection.
Point Level Switches
Siemens offers a range of point level switches designed for various industrial applications. These switches are used to detect the presence or absence of material at a particular point within a container or vessel. Some of the popular liquid level switch models include:
- SITRANS LVL100. This is a vibrating level switch suitable for solids and liquids. It is particularly useful in applications where material buildup is a concern.
- SITRANS LVS100. This is a capacitance point level switch designed for liquids, slurries, and solids. It offers high sensitivity and can be used in a wide range of industries.
- SITRANS LPS200. This is a capacitance level switch primarily designed for liquids and slurries. It provides reliable level detection in challenging process conditions.
- SITRANS LVS200. Another capacitance point level switch from Siemens is suitable for liquids, slurries, and solids. It offers robust construction and precise level detection.
- SITRANS LVS300. This is a rotary paddle level switch designed for bulk solids. It offers simple installation and reliable operation, even in dusty environments.
- SITRANS LPS300. A capacitance level switch is suitable for liquids and slurries. It offers advanced diagnostics and is suitable for demanding process applications.
- SITRANS LPS400. This is a vibrating point level switch designed for liquids and solids. It offers high sensitivity and can detect a wide range of materials.
Continuous Level Switches
Siemens offers a range of continuous level switches designed to provide accurate and reliable level measurements in various industrial applications. These switches are used to monitor the level of liquids or solids in tanks, vessels, and silos continuously.
One of the popular products in Siemens' continuous level switch lineup is the SITRANS LG series. These switches utilize different technologies such as radar, ultrasonic, and guided wave radar to suit different application requirements. They are known for their robust construction, high accuracy, and ease of installation and maintenance.
The SITRANS LG series includes models such as:
- SITRANS LG240. This is an ultrasonic level transmitter suitable for continuous level measurement of liquids and slurries. It offers reliable performance even in challenging environments.
- SITRANS LG250. This is a radar level transmitter designed for continuous level measurement of liquids, slurries, and solids. It provides accurate measurements even in applications with extreme conditions such as high temperatures and pressures.
- SITRANS LG260. This is a guided wave radar level transmitter suitable for continuous level measurement of liquids and solids. It is particularly useful in applications where there are changes in temperature, pressure, or dielectric constant.
Selecting the Right Siemens Level Switch
When you choose equipment for industrial purposes, your choice should be influenced not only by Siemens level switch price but also by several other factors:
- Determine whether you require spot level measurement (on/off control) or continuous level measurement (continuous monitoring). Consider factors such as measurement range, accuracy requirements, response time, and required output signals (analog, digital, or both).
- Understand whether you are measuring liquids, suspensions, or solids. Consider the physical and chemical properties of the medium, such as density, viscosity, dielectric constant, and particle size.
- Consider factors such as temperature, pressure, humidity, and the presence of corrosive or abrasive materials. Choose a level switch that can withstand the environmental conditions of your application without compromising performance or durability.
- Siemens offers level sensors based on various technologies, including ultrasonic, radar, guided wave, capacitive and electromechanical. Each technology has its own advantages and limitations, so choose the one that best suits your application requirements and environmental conditions.
- Experience the ease of installation, calibration, and maintenance requirements of a level switch. Choose a switch that is easy to install and maintain, minimizing downtime and operating costs.
- Ensure that the level switch you select complies with relevant industry standards and regulations such as ATEX, IECEx, SIL (Safety Integrity Level), and FDA regulations for food and pharmaceutical applications.
- Siemens provides technical support and expertise to help customers select the right level switch for their specific applications.
- Contact Siemens representatives or distributors to discuss your requirements and receive personalized advice.
