. . . in the factory

A major manufacturer of automobile parts uses System 10 to perform 100% audit of parts, with automatic rejection of nonconforming parts right off the line.  The long-term cost-effectiveness of such systems allows many companies to install multiple test stations throughout their plants.

A system for high-speed multispindle torque monitoring reduces production costs and improves productivity for a major transmission manufacturer.

This system of eight "satellite" System 10 mainframes linked to a central "host" mainframe monitors and controls a group of large turbo air compressors that are used to simulate flight conditions for jet engine testing (pressures must be developed to simulate air speeds of over 200 MPH).  Over 400 transducer signals are received, including displacement, force, flow, torque, and temperature.  The System 10 network interacts with a computer and PLC to generate all control signals necessary to maintain safe and effective compressor operation.

The above-mentioned racing team gives System 10 its toughest test by mounting a Model 10KU in the race car itself, to provide continuous monitoring of critical structural and performance variables while the car is racing.

Monitoring the Performance of a Carpet Shearing Blade     [Back ]

Using a Model 10K4TD mainframe (an earlier LCD version of the present Model 10K4T-DA) to receive input from a pair of high-resolution laser displacement sensors, this system continuously displays and controls the amount of carpet material removed by a shearing machine.  Providing immediate feedback and alarming, it automatically alerts the operator when the blade becomes worn or damaged.  For full details, see Daytronic Application Note No. 10K/4K.1.1.

Measuring Tire Contact Pressure and Slip     [Back ]

This system uses a Model 10KN9 to accurately measure the local triaxial contact pressure and tangential slip in the contact patch of a tire.  Because of the stability of temperature-compensated high-frequency pressure and slip sensors, the system can be used at realistic vehicle speeds.  Or it may be used at slow speeds for detailed study of the causes of uneven tread wear.  An optional History Card can be installed if local storage of data records is required, with real-time SPC made possible by the Model 10BSPCA History SPC Option Card.  For full details (with reference to the older Model 10KN7), see Daytronic Application Note No. 10K.3.1.

Real-Time Process Control     [Back ]

The above figure is a generalized block diagram for a Model 10KN6 system that enables enhanced operator process control, while providing real-time control charting of critical process variables, along with the ability to build a historical database for troubleshooting quality concerns after the fact and for identifying long-term process trends.  For full details, see Daytronic Application Note No. 10K.2.1.

Integrated Pump Testing System     [Back ]

The above block diagram represents a large System 10 "satellite" network for monitoring the performance of standard and custom-designed positive displacement pumps at a hydraulics lab facility.  All test data is acquired with minimal time skew.  Local nodes are responsible for monitoring all data for limit violations and controlling the precise test sequence at each stand.

Providing both local and central display of all measured and calculated parameters, the system consists of (1) nine independent Model 10K4TD data-collection "satellites" (earlier LCD versions of the present Model 10K4T-DA), each dedicated to a given test stand; (2) a Model 10K2C "satellite" (an earlier LCD version of the present Model 10K2D) dedicated to the power control center for all test-stand motors; (3) a "host" Model 10KN3 containing an IEEE-488 Auxiliary Interface Card, to accumulate all network data and transfer it at high speed to the lab's central PC; (4) System 10-interactive third-party Graphic User Interface (GUI) software resident in the central PC for graphic presentation, archiving, analysis, and reporting of all network data; and (5) a Programmable Logic Controller for sequencing the test process at each individual stand.

For full details, see Daytronic Application Note No. 10K.1.1.

Aerospace Strength and Durability Testing     [Back ]

In this extensive system for aerospace structural testing, multiple Model 10KN6-4 mainframes are linked via RS422 interface to a Model 10K488 Data Concentrator, which is in turn linked to the host computer via IEEE-488 bus.  The entire system can handle as many as 4864 separate strain-gage input channels, acquiring test data at high speed with virtually no channel-to-channel time skew (a condition that is absolutely essential for the integrity of such large data sets).  For full details, see Daytronic Application Note No. 10K.4.1.

Bearing Test Stand     [Back ]

This system involves precise feedback loops for sequential actuation of the pneumatic cylinder that houses the bearing under test, and for continuous control of flywheel rotation. 

Life-Cycle Testing of Pressure Switches     [Back ]

This system monitors the long-term performance of fluid pressure switches in a special environmental chamber, using a Model 10A60-4 Quad Voltage Conditioner Card and the analog track/hold function of multiple specially modified Model 10A79-4 cards for real-time capture of switch "make" and "break" pressures. The peak capture cards operate in a strictly event-controlled mode.  The graphs show the behavior of the peak cards' "B" and "A" outputs, respectively, where time "t1" is the moment at which the switch closes and "t2" is the moment the switch opens.  For full details, see Daytronic Application Note No. 10K.5.1.
