The LU240 has several benefits, some of which we have listed for you below:
The SITRANS Probe LU240 is a highly adaptable ultrasonic level transmitter designed to measure level, volume, and volume flow across various applications. It excels in level monitoring for water and wastewater treatment, chemical storage vessels, and small bulk hoppers. The LU240 can accurately measure levels in a range of storage-type vessels, simple process vessels with some surface agitation, liquids, slurries, bulk solids, and open channels, with measurement capabilities up to 12 meters (40 feet). It provides unmatched reliability through features such as Process Intelligence and Auto False Echo Suppression, achieving an accuracy of 0.15% of range or 6 mm (0.25 inches) for the 6 m and 12 m models. Additionally, pre-defined vessel shapes allow for the conversion of level measurements to volume, while volume flow can be measured in open channel systems like Parshall flumes or V-notch weirs using integral pre-defined flow structures. For vessels not covered by pre-defined shapes, a customized level-to-output linearization function is available. The LU240 supports HART communication on select models and offers mA output on all versions. The SITRANS mobile IQ app, compatible with Android, Apple, and Windows devices, enables effortless configuration and monitoring via Bluetooth.
Key applications:
The SITRANS Probe LU240, particularly in its 6 m and 12 m versions, supports the Highway Addressable Remote Transducer (HART) communication protocol, an open standard that enhances the functionality of the traditional 4 to 20 mA signal. This feature allows for efficient configuration and monitoring over a HART network, making it easier to manage multiple field devices simultaneously through multi-drop mode. Users can set up the polling address, device mode, and loop current values directly via the device's HMI or through compatible software.
The recommended tool for this purpose is the SIMATIC Process Device Manager (PDM) by Siemens, which is designed for easy configuration, monitoring, and troubleshooting of HART devices. Furthermore, the HART Electronic Device Description (EDD) specific to the SITRANS Probe LU240 is essential for successful configuration and can be downloaded from the Siemens product page. By utilizing HART communication, operators can enjoy enhanced diagnostics, streamlined device management, and improved operational efficiency in their applications.
Proper installation of the SITRANS Probe LU240 is crucial for optimal performance and accurate measurements. It is essential to ensure that the ambient temperature remains within the range of -40 to +80 °C (-40 to +176 °F) and the process temperature stays between -40 to +85 °C (-40 to +185 °F). The mounting location should be free from vibrations, and the sound path should be perpendicular to the material surface for effective signal transmission. Additionally, the display and local buttons should be easily accessible for programming, and cable entries must be positioned for convenient wiring. To prevent interference, avoid placing the device near high-voltage wiring or in direct sunlight; a sun shield may be necessary to protect it from sun exposure. Furthermore, ensure that the mounting surface is clean and suitable gaskets are used to prevent leaks, as improper mounting can compromise the device's functionality and longevity.
When connecting the SITRANS Probe LU240, it's essential to follow proper wiring practices to ensure reliable operation. Begin by using shielded, twisted pair cables, selecting wire gauges between AWG 22 and AWG 14 (0.34 mm² to 2.08 mm²) to minimize signal interference. Adhering to standard instrumentation wiring practices may require separate cables and conduits, so ensure compliance with relevant electrical codes. If routing the cable through conduit, only use approved hubs designed for waterproof applications. Since the non-metallic enclosure does not provide a continuous ground path, grounding-type bushings and jumpers should be employed. To make the connection, first remove the device lid, then strip approximately 70 mm (2.75 inches) from the cable jacket and thread the wires through the gland. Connect the wires to the terminal block, ensuring proper polarity, and tighten the gland for a secure seal. If using an optional display, connect its female end to the male four-pin connector and secure it in the enclosure before replacing the device lid. Proper connections will enhance the functionality and reliability of the SITRANS Probe LU240.
