Industrial Event Camera VOC for Installation Monitoring– from Pepperl + Fuchs

Within a modern intralogistics business automated high-bay warehouses with stacker cranes are a central element to their smooth and efficient operation. Allowing quick storage and retrieval of products and materials and optimising the available warehouse space. When installed in deep-freeze storage facilities their components must also be able to withstand the demanding requirements and extremely low temperatures. An uninterrupted cold chain has to be guaranteed throughout the movement of the goods stored there.

The Height of Reliability

Reliability, throughput, high precision, and high speed are the prerequisites of a stacker crane installation and failures and downtimes have to be avoided at all costs as any delay can trigger an expensive cascade of issues.

As you can imagine, most of the locations in the high-bay warehouse can be both difficult and dangerous for engineers to access for inspection. It would be ideal if the fault situation could be analysed before taking any further action, such as readjusting the crane.

As well as being ideal for Stacker Crane applications the VOC event camera also enables reliable monitoring of sensor-secured access areas, and if a machine or system is stopped by the access guarding, the recording of the trigger event is available for remote access.

The clever design engineers at Pepperl + Fuchs, a leading manufacturer of industrial control and automation product solutions, have created the ideal Industrial Event Camera solution, available to purchase from Kempston Controls today. Below we explore its abilities in this short write-up.

Industrial Event Camera VOC for Industrial Applications

The Pepperl + Fuchs Industrial Event Camera, for example, can be mounted directly on to a stacker crane, monitoring the storage and retrieval processes performed during its shift. The event camera continuously records the last 60 seconds of the video livestream in its integrated circular buffer. Faults or defined events in the sequence act as triggers for the camera to transfer cached data to permanent storage on an appropriate SD card.

These recordings last for up to 60 seconds before and after the event, enabling them to be used to identify the cause and the current status. Only relevant events are recorded and the image sequences can be used for immediate fault analysis or long-term process optimisation.

Unlike a continuous video sequence, event-oriented storage not only handles data streams economically, but also allows direct access to recordings. The date, time, and error message are displayed in the text overlay of the recording. A digital hardware input can record trigger signals that come directly from the control system or a trigger sensor.

Industrial Event Camera Benefits at a Glance

  • Event-driven video recordings up to 60 sec before and after the trigger signal
  • Fast analysis – recording of relevant events with timestamp and additional text
  • Easy integration into IT systems via REST API and to standard HMI displays with RTSP

Ex Isolation Barriers for when Reliability Matters, Created by Rechner Sensors

What is an Ex Isolation Barrier?

In any dangerous working environment intrinsically-safe protection plays a vitally important role in helping to protect personnel working in those specific areas, and of course the business and installation itself.

To safely use field devices such as sensors, solenoids, valves and transmitters, intrinsically safe isolation barriers will be required. These barriers typically don’t prevent signals or communication from getting through but are designed to stop dangerous levels of current and voltage. Barrier devices limit energy to low levels making them incapable of causing ignition, electrical shocks, fires, and explosions.

These devices are based on the galvanic separation of intrinsically safe and non-intrinsically safe circuits. This ensures a high degree of safety as there is no conductive connection between the hazardous area and the outside world.

Ex Isolation Barriers for a  wide range of industries

Isolation barriers are ideal for when there is an application in a hazardous area and the cost for explosion-proof protection is too prohibitive. Typical applications where you may find isolation barriers being used include the oil and gas industries, pharmaceutical, food and beverage, chemical production and numerous others.

An isolation barrier has to provide dependable Ex isolation, accurately transmit signals and also display error messages should a problem arise. These barriers also need to have a long life in the field and be easy to install.

Rechner Sensors, a leading manufacturer of industrial process control equipment has also created a comprehensive range of Ex isolation barriers that are available to buy from Kempston Controls today
