SicWave – 80 GHz Free-space Radar Level Detection for all Liquids and Solids

The storage of products such as grains, sugar, ore and liquids can take up a lot of space, typically utilising silo systems which can reach considerable heights. Measuring the level of product within these storage facilities can be difficult at the best of times where both the height and the media within can cause various issues with accurate level sensing. Similarly, production processes that involve stirrers and preparation tanks can create internal environments where accurately measuring the level of the contents within is challenging.

Dust and Foam Frustrations

Dust, moisture, foams, the build-up of residues and other obstructions within a storage or processing vessel can frustrate your average sensor, leading to down time, additional costs and frustration. What you need is a sensing solution that can deliver reliable level sensing results no matter how tall the silo or how demanding the process and the media involved prove to be.

To address these challenges and more, SICK, world renowned for their sensor solutions, have created the high-specification SicWave LFR and LBR ranges of level sensors, these sensors utilise an 80 GHz free-space radar technology delivered via a highly-precise narrow beam that is a thousand times more sensitive than previous generations 26 GHz radar technology.

SicWave LBR – For Solid Media Level Detection

SicWave LBR sensors

Demanding situations require dedicated solutions, the SicWave LBR free-space radar provides continuous non-contact level measurements, is highly resistant to external interference, dust and deposits and works with all solids. A high-contrast built-in LCD display option is available, aiding set-up and installation and providing the user with essential sensor feedback data.

SICK Photoelectric Sensors Phase Out

Due to the increasing demand for photoelectric sensors in industrial environments, SICK constantly strives to update and improve its portfolio of sensors while maintaining its focus on providing customers with the best solution.

To meet the demand, SICK has analysed their existing range of photoelectric sensors and after a long period of continuous availability have decided to phase out older product families. Affected ranges include the W14-2, W18-3, W23-2 and W27-3 product families. Here at Kempston Controls, we will continue to hold the existing range until all stock is sold while also offering the replacement models.

The new W16 and W26 Photoelectric Sensors.

Thanks to new technology, the W16 and W26 photoelectric sensors detect shiny, uneven, perforated and transparent objects more reliably than ever and aren’t affected by unwanted light reflection.
Not only more reliable they are capable of using LED feedback to alert the user to any issues and to allow adjustments within seconds. The Smart Sensors W16 and W26 detect and translate their situation to digital data which in turn can then be communicated via IO link or Bluetooth opening the door to Industry 4.0 and intelligent factories.

Thanks to the Bluetooth interface, it is possible to access the sensor data from any mobile device and enables the user to optimise performance in a few clicks.

Photoelectric SensorsHighlighted Features of W16 and W26 Photoelectric Sensors

The T-Easic FTS Range – Double-up your Pump Protection

Ensuring a pump doesn’t run dry or operate at a lower pressure than specified can be vital in many industrial and commercial processes. Falling to stop a dry-running pump could result in costing you a considerable amount of money and time in the form of process down-time, damaged production components, expensive replacement pumps and machinery.

Simplifying the monitoring of the flow of liquids, oils and other fluids and their temperature while reducing your dependency on multiple devices within your process would be ideal. Thanks to the ingenuity and innovation of the clever people at SICK those requirements have been met with the T-Easic FTS range of calorimetric fluid flow and temperature measuring sensors.

Vistal and Stainless Steel T-Easic Flow and Temperature Sensors.

It’s Easic with the T-Easic FTS Range of Calorimetric Meters

The T-Easic FTS range is essentially two sensory devices in one, incorporating the calorimetric principle of operation to measure both the flow of a liquid within a fluid transport pipe and also its relative temperature. Although the T-Easic FTS flow switch range has been optimised for use in oil and water, with built-in factory presets to allow for easy set-up, it is compatible with a whole range of liquids and can be calibrated easily via teach-in.

Vistal Flow and Temperature Sensor.

Staying ahead of the competition when it comes to the IIOT, the T-Easic FTS range comes with a built-in IO link interface and has been designed to allow for quick and easy adjustment of its process and configuration settings at any time via an IO-Link Master. IO link also has the benefit of not requiring any complicated wiring or interfacing connections which means you can set up your T-Easic FTS device even easier, saving you more time and money and is the perfect addition to the industrial internet of things.

Available in two versions to suit a multitude of applications:

The durable and hard wearing 316L stainless-steel version has been designed for hygienic installations. Able to withstand wash downs and the cleaning and sterilisation in place processes typically found in the food and pharmaceutical industries and can operate in temperatures up to 150 degrees C.

The tough VISTAL bodied industrial version comes with a built-in OLED 180-degree rotatable display and operating buttons to allow you to read values on-site, and is tough enough to handle intensive industrial cleaning processes.

Vistal T-Easic Flow and Temperature Sensor demonstration.

What is the Calorimetric Principle?

The T-Easic FTS Thermal Flow Switch provides flow and temperature monitoring in one device using the calorimetric principle of operation, one of the most optimum engineering solutions for a wide range of flow applications.

The sensor probe, when installed in a suitable fluid transport pipe is heated up, and as the liquid medium flows it cools the probe. The relevant temperature drop is proportional to the flow speed of the liquid within the pipe, of course, if there is no change then there is no flow. The T-Easic FTS  evaluates the detected temperature difference and calculates the relevant values to determine the flow of liquid triggering a system response such as a pump shut down in the case of zero flow.
