Ultrasonic Sensor Technology for Safety in All Areas with the Pepperl + Fuchs USi- safety

The USi-safety ultrasonic sensor system from Pepperl + Fuchs is breaking down the barriers imposed by other sensing solutions. Whether operating in challenging, dusty conditions or outdoor  – industrial machines, vehicles, processes  and the people using them can be protected using the advanced ultrasonic technology utilised in these sensors.

Intelligent Design for Every Situation

When a miniature sensor unit is detached from the control interface it means the sensor system can be used in confined spaces, and the unique design allows the sensor to cover an elliptical 3-D sound field with opening angles of ± 17° and ± 5°, providing improved safety.

Manipulation protection and Parameterisation

Preventing safety functions from being overridden is challenging, the USi-safety system features a teach-in process when a machine part is used as a reference target, the sensor can register deviations immediately. Comprehensive parameterisation software and automatic documentation make commissioning the ultrasonic sensor system quick and simple.

Elliptical Sound Field for a Wide Sensing Range

The USi-safety features a strongly elliptical sound field, creating a wide sensing range in one plane and a narrow sensing range in the other. The system can be used just above ground level or close to a wall, allowing the sensor to detect targets or obstacles that are overhanging or near to the ground.

Two Category 3 PL d Safe Systems in a Single Evaluation Unit

A maximum of 2 ultrasonic sensor units can be connected to the evaluation unit. These ultrasonic sensor units have a single-fault tolerance, 2-channel structure. A safe sensor system is achieved even when only one sensor unit is connected. One signal output and safe OSSD outputs in accordance with category 3 PL d are available.

This capable ultrasonic safety sensor system can be used in applications where left/right or forward/reverse movements need to be safeguarded, such as on Auto-Guided Transport (AGT) Systems. Applications can be implemented in which both sound fields are focused directly adjacent to each other or overlapping, securing the widest possible collective sensing range.

ultrasonic sensor USi-Safety

A Complete System

The USi-safety ultrasonic sensor system consists of an evaluation unit, a sensor unit, a temperature sensor, and the software.

The evaluation unit contains two microcontrollers that monitor the connected sensors, their own hardware, and each other to ensure that the components are functioning correctly. In addition, there is an input for a temperature sensor and a USB interface for parameterisation via a PC.

IP69K protection makes the system’s 2 ultrasonic sensor units suitable for even the most demanding conditions. With their miniature design, they can be flexibly integrated into numerous applications. The system reliably detects even the smallest objects within their wide 3-D sensing range.

The parameterisation software allows a wide range of settings such as switch points, output logic, safety parameters, and ultrasound-specific parameters to be customised. The interface can be used to initialise periodic tests and automatically generate safety protocols.

USi-safety Ultrasonic Sensor Application Examples

Collision Avoidance in the Fork Tip

Reliably preventing collisions involving driverless forklifts is ideal for the USi-safety ultrasonic sensor system. As the technology is resistant to dirt, temperature, air currents, and humidity, it significantly expands the area of use for these automated guided transport systems.

Machine Safeguarding in the Wood Industry

Usually, machines are safeguarded by photoelectronic light curtains. The USi-safety, used as a sound curtain, is insensitive to wood dust and other particles and can withstand demanding environments.

Personal Safety in Lane-Guided AGVs

Lane-guided AGVs follow a lane on the ground and transport goods from one station to the other. In this process, the detection range of the sensors can be quickly and easily adapted via the parameterisation software to help prevent collisions.

ST-G RFID Sensors with Multi-tag Ability for Industrial Process Control and Safety Applications

RFID or Radio Frequency Identification uses a digitally encoded tag with information that can be read and captured by a reader using radio waves. A basic RFID system consists of the tag, and an RFID reader. Typically, an RFID tag transmits digital information to an RFID reader within close proximity, which then converts that information into usable data for interpretation and a system response from another piece of equipment. RFID has found multiple uses within industry, including process control and the increasing the safety of machine guarding.

Pizzato are a well-known manufacturer of process control equipment including a broad range of machine access and safety control devices including Safety Hinges, Safety Modules and Limit Switches.

RFID Sensors – Positional Accuracy

The Pizzato’s ST-G RFID sensors extend all the technology used in their traditional ST-D series sensors, and do that in an even more compact housing.  The RFID technology within provides each actuator with different coding, making it impossible to tamper with a device by using another actuator of the same series. Ultimately, this means millions of different coding options are possible for the actuators, classifying them as high-level coded actuators according to EN ISO 14119.

Versatile, these RFID sensors are suitable for a host of process control applications and the clever housing design allows the same sensor to be used on both left and right-hand safety doors by simply rotating the sensor onto itself. The industry standard 22 mm fixing pattern and compact external dimensions means traditional magnetic sensors can be easily replaced with these more sophisticated RFID Sensors, providing maximum reliability and safety. The robust monolithic housing allows the ST-G RFID Sensors to be used in even the most aggressive industrial environments and the signalling LEDs providing immediate diagnostics of the input and output operating states.

ST-G RFID Sensors and Actuators

Within this range of industrial sensors is an extended temperature version that is certified by ECOLAB, this ensures that these sensors are ideal for machines used in the food and pharmaceutical industry. Constructed with redundant electronics means that the maximum PL e and SIL 3 safety levels can be obtained via the use of a single device on a guard, avoiding expensive wiring and speeding up installation.

ST-G RFID Sensors and Actuators

Multitag Programming

What sets the ST-G series of RFID sensors apart from the competition is an exceptional feature which Pizzato has called Multitag. Multitag is the ability of the sensor to recognise 2 or more actuators in a processing environment. The internal firmware can be factory programmed, memorising up to 16 actuators and associating a different device behaviour to each once the actuator has acknowledged the sensor. This ability allows the user to activate or deactivate the sensor outputs and send information regarding which actuator is in front of the sensor via an O3 signalling output. This signal can be sent to a PLC and processed.

ST-G RFID Sensors and Actuators

This Multitag function is ideal for machines and industrial processes with several workstations that require various operating modes based upon the recognition between different actuators and the sensor – such as during the change-over of machine parts, robot positioning during manufacturing, industrial process rotary tables control and so on.

For safety gate applications the combination of a sensor and 2 actuators can fully monitor safety guard opening and closing by acknowledging when the guard is fully open and again, fully closed, eliminating the uncertainties caused by incomplete guard positioning and ultimately increasing intrinsic safety.

RFID Sensor – the SICK RFU61x, Big Ability in a Small Package

What is RFID Technology?

RFID, or Radio Frequency Identification, is a method of transferring information between two entities, these being an RFID tag that carries information and a RFID scanner or reader to decode that data. Using electromagnetic field technology, when an item adorned with an RFID tag passes a suitable scanner that information is captured, extracted, and acted upon, or not, by the control system that is interpreting the data.

RFID tags and readers do not need a line of sight to function, they merely need to pass within the detecting range of each other. RFID Sensor tags can be found in many applications, such as attached to clothing in a store, under the skin to identify pet ownership, in a car key fob or in production operations, monitoring the progress of a product through each stage of manufacture, all of them containing data that is accessible by a suitable reader.

RFID technology exists in many forms and for many purposes and SICK, world-renowned manufacturers of sensors and sensing solutions are no strangers to RFID technology, here we preview the RFU61x UHF RFID Sensor.

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.
