Testing Dishwasher Performance Using Modular Data Acquisition

Delphin TopMessage Customizable Real-Time Systems CHESTERLAND OH-The month from the month of the month of january 30, 2012

CAS DataLoggers lately provided the information acquisition solution for almost any customer operating an exam laboratory to gauge the performance of residential dishwashers. The lab contained over 40 test bays for testing a number of dishwasher models. Specialized equipment of these bays monitored water consumption and water temperatures within the dishwashers with the different washing cycles. Temperature measurement was conducted with type K thermocouples along with the water consumption was measured using flow sensors with pulse signal outputs. Test leads looked for just about any high-speed data acquisition system capable of interfacing with your sensors with highly accurate measurements, fast signal processing capacity, and intuitive, simple configurability and operation. The client planned on integrating additional test bays requiring more inputs later on, and thus needed a modular system so they could upgrade the unit easily with elevated input and output channels once the need came to exist.

The client produced a built-in application using Delphin TopMessage data acquisition and control systems, put into a control cabinet within the test laboratory, together with ProfiSignal Basicsoftware. The TopMessages’ compact designs ensured a simple match the cabinet, while using the entire measurement systems composed of merely one TopMessage being a specialist dental appliance 3 TopMessages becoming slave extensions. The client was offered numerous specific modules, selecting 4 ADVT modules enabling Type K thermocouple measurement and 4 DIOT modules allowing pulse/flow rate measurement to uncover water consumption. The thermocouples and flow sensors were connected to the devices without employing any intermediate converters.


The Delphin system architecture contained your computer running ProfiSignal connected via LAN while using the master TopMessage which connected while using three slave TopMessages via CAN-bus. 40 flow sensors obtaining a pulse growth and development of -1000 Hz were connected via DIOT modules to among the slaves, and 40 type K thermocouples calculating hot and cold levels via ADVT modules were connected with another slave.

The stand-alone TopMessage devices created a modular and scalable system wealthy in precision and around 24-bit resolution with true differential inputs furthermore to 2 slots for analog or digital input or output cards along with a CANbus for expansion modules. Housed within industrial-grade enclosures, the TopMessages also featured signal conditioning, an Ethernet interface allowing you to connect along with your pc for data analysis, and screw terminals for secure connections.

Design engineers found the Delphin ProfiSignal process visualization and monitoring software simple to use, due to this the customer could easily get the whole application themselves. The effective software channels configured within the TopMessage calculated the flow rate and overall water consumption aboard level. The information storage was triggered for each bay individually through command buttons within the application, along with the data of every test cycle was recorded for the 1GB TopMessage memory obtaining a capacity of 128 million data records. Additionally, the information of every test cycle was archived instantly having a database while using the ProfiSignal application while using the built-in recorder function. The approval was organized in 7 bays, and each bay might be operated individually while using the corresponding start/stop buttons. While using the overall control screen, the operator saw the status of each bay coupled with current water consumption. Using additional navigation buttons, the engineers could open a design diagram to discover the consumption, flow rate and temperature–all displayed in a online trend.

The client recognized several strengths after installing the Delphin TopMessage data acquisition systems in their test lab. Initially the client was offered numerous I/O modules to decide on the right solutions for application, with some other modules readily available for a number of channels and sensor types. The TopMessages produced to have an easy install, due to this the initial test run was performed soon after installation. Likewise, the configuration of all of the temperature sensors was equally hassle-free since no additional ripping tools and signal conditioning unit was needed. Another major benefit was the TopMessage’s modular design which enabled future growth and development of the testing program that includes a lot more inputs and outputs. Overall, plant engineers found that the TopMessage data acquisition system was both dependable and highly accurate, and operators reliable the client-friendly ProfiSignal Fundamental software for an entire automation and reporting solution. ProfiSignal also setup convenient online mimics to check out temperatures in every single bay, in addition to onOraway status, through getting surgery much like Home home home windows Explorer. Additionally, a network interface enabled the TopMessage systems to obtain built-in to a TCP network to get directly connected together with your pc workstation or laptop/small netbook.
