Gearbox test stand - Monitoring and alarm functions

Gearbox is the main component in an automotive transmission system. The amount of vehicle noise is an important indicator on measuring the overall quality of vehicle, In order to locate the excessive noise caused by gearbox noise when a heavy vehicle is accelerating, the noise and vibration on the key parts of the gearbox were tested and analyzed.

Transmission test stands of varying complexity and size are equipped with Delphin products for measurement and automation technology. Measurement procedures can then be implemented for specific requirements during product development and manufacture. A special feature is the single system’s ability to acquire vibration data at casings, bearings and shafts as well as to process data such as oil pressures, volume flows, bearing temperatures, torques and rotation speeds. Synchronous acquisition of all data is therefore guaranteed. A fully integrated system requiring no expensive interfaces is possible. The system is equipped with options for automation, analysis and evaluation which can be performed directly at the process using the Expert Vibro and ProfiMessage devices, and at a PC using the ProfiSignal software.

Cleanroom Environment monitoring – Temperature & Humidity

Continuous and manipulation-safe data acquisition and documentation is especially important in the pharmaceutical industry for production and storage requirements as well as for research and development. According to FDA Part 11, data acquisition and monitoring systems in cleanrooms must operate in compliance with GAMP/GMP guide-lines. Measurement data and limit values for parameters such as temperatures, humidity, particle count and pressures need to be acquired and monitored as well as archived in a manipulation safe format. Any user intervention relevant to the processes must also be recorded to an audit trail.

Energy Consumption Monitoring - EN50001

EN50001 standard requires high energy consuming industries to implement energy saving measures and, when required, energy management systems. Energy consumption data therefore requires recording which can be performed using Message devices. Due to their LAN interfaces, these can be located throughout a company and installed directly at the plant and machinery. Consumption data can then be transmitted to a central data server or workstation PC. Universal inputs can directly measure analog units such as pressures and flows. Pulse inputs and/or serial interfaces can acquire data from electric, gas and water meters. Characteristic values for consumption data are processed and monitored directly within the devices. All the information can be analyzed, portrayed and accounted for using the ProfiSignal software.

Sequential Event Recorder

To analyze switching procedures, switching times and processes requires the acquisition of digital signals with high-level time resolution. Sampling rates in data loggers need to be much faster than typical PLC cycle times especially for fault analysis. An event recorder must also be capable of reliably processing relay and contact bouncing.

Message and Expert devices are ideal for such tasks. Digital inputs record events at µsec resolution. Every input is recorded in parallel to enable precision determination of switch times. Depending on requirements, analog data can also be recorded in parallel. Internal logic and trigger channels enable events to be recorded and saved along with pre-and post-data.
