Reclaiming your day - with an ultrasonic transmitter from Siemens you can ignore

Walking through their facility, operators at a wastewater treatment plant don’t stop all that often at the filter beds anymore.

At one time, plant workers were visiting the filter beds quite regularly, tending to guided wave radar instruments chosen for particularly narrow installation space. However, contacting instruments and organic matter are not an ideal mix, and operators were continuously called to the filter beds. Material sticking on the cables caused high-level spikes in measurements—interference that a busy wastewater treatment plant can’t afford.

But what do you install in an application that needs the best of both worlds: a hardworking and rugged device that provides reliable measurements—without a high-end price tag?

Enter Siemens SITRANS Probe LU240.

This compact, rugged, and high-performance ultrasonic transmitter gives operators the level, volume, and flow measurements they need with field-proven echo processing. Separating true material level echoes from false, Process Intelligence is effective, accurate, and unique to Siemens level devices. What does this mean for an application? Reliable readings combined with rapid response to changes in material levels.

Tackling your application challenges

From liquid chemical inventory to monitoring small process vessels to level measurement in the environmental industry (including filter beds!), this versatile device lets operators get on with their day. Easy setup with its 4-button user interface or remote configuration with SIMATIC PDM will have users up and running in no time.

And for dirty applications or those with buildup? As in those filter beds, above, the non-contacting SITRANS Probe LU240 (186-0287) has maintenance-free active face technology, which keeps the sensor clean and delivers the reliable performance plants need.

Rugged applications in harsh environments? Choose the IP68 fully potted transmitter with its fully encapsulated PVDF sensor that’s resistant to corrosion, chemicals, and extreme shock.

Let’s take a closer look:

• State-of-the-art Process Intelligence echo processing provides improved accuracy and repeatability
• For applications needing process temperatures, this is now available as a measurement value: one instrument, two variables
• Battery and solar-power friendly thanks to low start-up current and 10.5-volt operation
• Reduced blanking distance and near-range specification decreases waste while boosting asset utilization
• Engineered to last—at a price point that won’t break budgets

Digitalization—evolving your business

Plants can connect SITRANS Probe LU240 to their control systems so operators see exactly what’s happening in their applications at all times—either from the comfort of the control room or on the go using the SITRANS RD500 remote data manager’s web interface.

Unparalleled access to intelligent instruments means users now have complete knowledge of plant operations. Digitalization integrates critical field data into a business’ entire operations, unlocking new opportunities to analyze processes and identify areas for improvement.

At the end of the day

With more than 40 years of level experience, combined with global sales and technical support for all of a plant’s instrumentation needs, Siemens is the world’s partner in ultrasonic level measurement.

And those filter beds? By using a SITRANS Probe LU240 transmitter, with its large signal power and capabilities to mask unwanted reflections, operators achieved consistent level measurements in the filter beds, which they now just walk on by.

The solution is clear: users save time and maintenance costs with SITRANS Probe LU240’s transparent lid. Check process values with ease during manual observations without removing the device’s lid.
