SITRANS LC300 is an inverse frequency shift capacitance continuous level transmitter for liquids and solids applications. It is ideal for standard industrial applications in chemical, hydrocarbon processing, food and beverage and mining, aggregate and cement industries.
SITRANS LC300 is a 2-wire level measurement instrument combining a sophisticated, yet easy-to-adjust microprocessor with field-proven probes. It is available in two versions: rod and cable.
SITRANS LC300 has a stainless steel process connection with PFA-lined probe. Materials with low or high dielectric properties are accurately measured and Active-Shield technology helps in ignoring the effects of buildup near vessel nozzle.
Key Applications: Conductive and non-conductive media including liquids and solids in standard industrial processes and bulk solids applications involving dust or chemical processes involving vapour
Supplementary Components are designed to work with most types of instrumentation to provide enhanced functionality such as remote displays and remote monitoring solutions.
Don’t forget that the safest engineered level measurement solution includes switches for back-up, overfill, low level and dry run protection.

Echomax® XPS transducers use ultrasonic technology to measure level in a wide range of liquids and solids.
The transducers can be fully immersed, are resistant to steam and corrosive chemicals, and can be installed without flanges.
The XPS series offers versions for various measuring ranges up to 30 m (100 ft) and up to a max. temperature of 95 °C (203 °F).
During operation, the EchoMax transducers emit acoustic pulses in a narrow beam. The level monitor measures the propagation time between pulse emission and its reflection (echo) to calculate the distance.
Don’t forget that the safest engineered level measurement solution includes switches for back-up, overfill, low level and dry run protection.

ST-H transducers use ultrasonic technology to measure level in chemical storage and liquid tanks.
The narrow design of the ST-H allows the transducer to be mounted on a 2″ (50.8 mm) standpipe. When mounted correctly, it is completely protected from the process and can even be used in harsh, corrosive environments.
During operation, the ultrasonic transducer emits acoustic pulses in a narrow beam perpendicular to the transducer face. The level transceiver measures the propagation time between pulse emission and reception of the echo to calculate the distance from the transducer to the material. Variations in sound velocity due to changes in temperature within the permissible range are automatically compensated by the integral temperature sensor.
Key Applications: chemical storage, liquid tanks

Echomax® XRS-5 ultrasonic transducer provides reliable, continuous level monitoring of liquids and slurries in narrow lift stations/ wet wells, flumes, weirs and filter beds using a beam angle of just 10° and a CSM rubber face.
The XRS-5 is non-contacting with a measuring range from 0.3 to 8 m (1 to 26 ft). Advanced echo processing ensures reliable data even in conditions with obstructions, turbulence and foam.
The hermetically sealed CSM rubber face and the PVDF copolymer enclosure are designed for maximum resistance to methane, salt water, caustics and harsh chemicals common to wastewater installations. With an IP68 degree of protection, this rugged sensor is fully submersible in the event of flood conditions. Use a submergence shield if full submergence is possible in the application. A submergence shield will maintain a high level reading output during submerged conditions.
The low-cost XRS-5 transducer is compatible with a full range of Siemens controllers, from a basic system for high/low alarm or simple pump control, up to advanced control systems with communications, telemetry and SCADA integration capabilities.
SITRANS LU150 is a short-range integrated ultrasonic level transmitter. This general purpose, 2 wire, 4 to 20 mA loop powered transmitter is ideal for liquids, slurries, and bulk materials in open or closed vessels to 5 m (16.4 ft).
SITRANS LU180 is a short-range integrated ultrasonic level transmitter. This intrinsically safe (ATEX, CSA, FM, IECEx, NEPSI), 2 wire, 4 to 20 mA loop powered transmitter is ideal for liquids, slurries, and bulk materials in open or closed vessels to 5 m (16.4 ft).
The transducer is available in PVDF copolymer, making the device suitable for use in a wide variety of applications.
SITRANS LU150/LU180 is easy to install and maintain, and can be quickly removed for cleaning as required by the food, beverage and pharmaceutical industries.
The reliability of the level data is based on the Sonic Intelligence echo processing algorithms. A filter discriminates between the true echo and false echoes from acoustic or electrical noises and agitator blades in motion. The ultrasonic pulse propagation time to the material and back is temperature-compensated and converted into distance for display, analog output.
Supplementary Components are designed to work with most types of instrumentation to provide enhanced functionality such as remote displays and remote monitoring solutions.
Don’t forget that the safest engineered level measurement solution includes switches for back-up, overfill, low level and dry run protection.
