SICK PBS plus Pressure Sensor – Added Versatility for Pressure Monitoring Installations

The PBS plus Pressure Sensors from SICK, expands upon their existing PBS Sensor range, they have been purposely designed for demanding industrial applications, providing an electronic pressure switch, pressure transmitter and display all-in-one, available with up to two switching outputs, analogue output and IO-Link communication.

PBS plus Pressure Sensor in actionSimple to set-up, the PBS plus features three large pushbuttons and an easy-to-read display and they can be set-up using IO-Link, which also provides diagnostic functions and simplifies predictive maintenance, external parameterisation also makes handling easier and ensures lower maintenance costs.

 

Easily adapted for countless installation possibilities

The PBS plus range of Pressure Sensors are easily adapted to suit numerous installations, for example, the housing can be rotated twice, once at the process connection and then at the display cap, meaning the electrical connection can be rotated in the desired direction at any time.

Versatile, thanks to the large number of available process connections, including a flush-mounted membrane for sticky, crystallising and viscous media, helps to widen the integration possibilities of the PBS plus Pressure Sensor series. With measuring ranges of 0.4 bar to 1,000 bar (gauge pressure), the PBS plus can be used in many different applications. It also has absolute pressure and vacuum measuring ranges.

PBS plus Pressure Sensor Applications

  • Measurement of system pressure in hydraulic systems
  • Control of the clamping pressure in CNC machines
  • Monitoring of the cylinder pressure in hydraulic presses
  • Control of the pressure in cooling and lubricant systems
  • Hydrostatic level measurement
  • Measurement of system pressure in PET bottle production

 

 

The best in challenging conditions

Whether in aggressive environments, with measuring ranges of 0.4 bar to 1,000 bar, or when used with viscous liquids, the PBS plus takes challenging environments in its stride. Due to the integrated electrochemical cell with fully welded stainless steel membrane, it can withstand even aggressive media, as no sealing medium is required between the electrochemical cell and the membrane. Temperatures between –20 °C and +85 °C are no problem for the PBS plus.

Carlsberg and CleverLevel

Case Study: Carlsberg’s Clever(Level) Overflow Switch

Heavy build-up of foam in the excess yeast tanks at Carlsberg

In 2018, The Drinks Business reported that on average Britons will consume six billion units of alcohol over the festive period. With this in mind and Christmas just around the corner, we thought we’d take a look at how the Baumer CleverLevel Overflow Switch, available from Kempston Controls, helps in the process of fermentation.

When it comes to fermentation, yeast is an essential ingredient yet it can also be very problematic. Recently, Baumer helped the Carlsberg brewery solve a problem with leftover yeast from the fermentation process using the CleverLevel Level Overflow Switch.

Carlsberg and Baumer’s have been working together to provide solutions and instrumentation for over a decade, beginning with the productions lines in Copenhagen and continuing in their new home in Fredericia, Denmark. From Fredericia, Carlsberg operates one of the largest breweries in the world with 2.2 million hectolitres of beer being produced annually and 120 million beers being sold globally.

What is Fermentation?

The process of fermentation is when the yeast converts the glucose in the wort (a mixture of sugars) to alcohol and carbon dioxide gas which gives the beer its alcohol content and its carbonation. After 4 to 6 days when the fermentation is nearly complete the majority of the yeast has settled at the bottom of the fermentation tank. This excess yeast is then removed and reused for future fermentation processes before filling an excess yeast tank and then being sold as animal feed. It was in this final stage of filling the excess yeast tanks that Carlsberg experienced overflow problems due to the heavy build-up of foam which was preventing the traditional vibrating fork sensory technology from being triggered.

Solution? Cleverlevel from Baumer

CleverLevel level detection switches use frequency sweep technology to detect the filling level and are ideal for any media, whether it’s wet, dry, sticky or in this case foam, whereas the traditional vibrating fork simply can’t recognise the range and condition of media. Maintenance-free, due to the minimal installation depth and the self-draining sensor tip, the Cleverlevel also meets 3A and EHEDG standards. It can be configured visually and easily via the dedicated software and the FlexProgrammer.

The switching range can be adjusted to ignore foams during maximum or minimum monitoring. Using the same function, CleverLevel can also be used when the level switch is supposed to ignore adhesive substances, for example: if a tank is empty, but the sensor and tank wall are covered with excess media the sensor will still function correctly.

CleverLevel – Level switch LFFS/LBFS and configuration tool FlexProgrammer

In comparison to using traditional vibrating fork level sensors where individual versions are needed for dry, wet and sticky media the CleverLevel can be used for the entire process: from when the barley arrives in the storage tanks to the finished beer.

Since using CleverLevel, Carlsberg has completely eliminated their problem with overflows in excess yeast tanks but have also seen other benefits. With no overflows, Carlsberg has become more environmentally friendly, as left-over yeast is not entering the sewage system while also saving money and optimising the fermentation process.

Now that calls for a Carlsberg! Probably!

The Clever(Level) Alternative to the Vibrating Fork

Industries that produce food for human consumption will, at some point in one or more of their numerous process applications, have a need to utilise level sensing devices of some description. These essential devices will carefully monitor the levels of various ingredient tanks and transfer systems and, of course, meet the stringent approvals and standards.

These devices must be robust, resistant to chemicals and regular washdowns and have very little in the way of irregular features thus preventing ingredients from becoming trapped and causing health concerns. What is also needed from your sensory solution is the prevention of dead and stagnant zones, such as those found in traditional Tri-Clamp installations where the processed product can become trapped due to the choice of level detecting device that is being used and where and how it is installed within the process.

The green area shown in the traditional Tri-Clamp installation represents a zone where the processed product may become trapped.

 

Baumer, one of the world leaders in the design and manufacture of sensory technology, has developed a level sensor that is capable of functioning in all media types and can cater for all level sensory applications and also prevent stagnant zones where processed food may become trapped.

 

The CleverLevel Sensor

Whether your process includes products that are powders, liquids, are paste-like, foamy or sticky and viscous in nature the CleverLevel is the only single maintenance-free sensor type available that can cater for all product detection types.

 

Separate Layer Detection – Differentiation between the individual medium states such as foam and liquid and mask or detect them as necessary.

Viscous Media – Sticky products can adhere to the sensor causing false readings with other sensors. Not a problem with the CleverLevel!

Bulk Goods – Works with all media and won’t suffer any deposition or jamming issues, reducing process down-times, unlike traditional vibrating fork sensors.

Process Control – Capable of detecting dry running pumps which can lead to metering issues or damage to the system, adaptable to any installation.

 

The Clean and Sweep

The Cleverlevel is suitable for media types include foamy liquids, sticky and bulk goods.

The CleverLevel utilises a frequency sweep technology which is the process of using the medium and the sensor circuitry to create a capacitor with the medium determining the capacity value. A resonant circuit occurs together with a coil in the sensor electronics, and depending on the measured resonance frequency and established thresholds a switching signal can be triggered.

Processing – the Benefits

Stabilised processing – easy differentiation between separating layers (foams, liquid, oil). No incorrect processing messages due to adhesion, turbulence, suspended solid matter. No excessive process shut-downs.

Easy Installation and retrofitting – Installation flexibility and optimal positioning thanks to the short immersion length and compact design. A wide and varied selection of process connections and adaptors available.

One sensor for all media – reducing overall inventory – maintenance free and simple to clean and easy to operate with bright status LED.

IO-Link interface – effortless communication and automated process monitoring and control with Industry 4.0 and the IIoT.

Adaptable

Whatever your level detecting needs the CleverLevel from Baumer is certainly a step above your standard industrial level sensing solutions, offering a huge range of benefits that are hard to ignore, from safer, cleaner and more capable level detection methodology compared to traditional Tri-Clamp installation sensors, to reducing your dependency on a multitude of different sensor types.  Available in a range of lengths and in an assortment of fittings types, they are also compatible with Baumer’s existing range of Hygenic Adaptors,  including Tri-clamp, threaded and weld-in sleeves etc. to suit your new or existing retrofit installation.
