Applications

The Daytronic 3500 Series represents a versatile, low-cost solution to a wide range of data acquisition, indication, and control applications, just a few of which are illustrated below.

Click on the respective arrow to go to the application of interest.

"GO NO-GO" Dimensional Gaging of Parts (Model 3530)

Automatic Grinder Shutoff (Model 3530)

Measuring Tip Height (= Bearing Placement) of Ball Point Pens (Model 3530)

Flow Indication (Model 3540)

Measuring Motor RPM (Model 3540)

Smoke Stack Flow Monitoring (Model 3560 network)

Monitoring Height of Relay Contact (Model 3560)

Monitoring Compression Force in a Pill Press (Model 3570)

Brake Testing (Model 3570)

Stress Analysis Using External Bridge Completion (Model 3570 with Model 10CJB-2)

Testing Motors for Proper Stall Torque (Model 3570)

Batch Weighing with Motor Control (Model 3570)

Bearing Friction Testing (Model 3578)

 

"GO NO-GO" Dimensional Gaging of Parts     [Back ]

See the Model 3530 LVDT Conditioner


Automatic Grinder Shutoff     [Back ]

See the Model 3530 LVDT Conditioner


Measuring Tip Height (= Bearing Placement) of Ball Point Pens     [Back ]

This measurement must be within ±0.0040 inch.  The "HI", "OK", and "LO" alarm outputs of the Model 3530 LVDT Conditioner activate solenoids for the sorting of good and bad pens.


Flow Indication     [Back ]

See the Model 3540 Frequency Conditioner


Measuring Motor RPM     [Back ]

See the Model 3540 Frequency Conditioner


Smoke Stack Flow Monitoring     [Back ]

To ensure that gas flow in plant emission systems complies with current EPA regulations, networked Model 3560 Voltage Conditioners receive and process 0-5 VDC outputs from thermal flowmeters at the top of each stack, transmitting finished data to the control center for further processing and recording.  Where compliance to a yearly mass emissions allowance is of concern, gas mass flowmeters can also be employed.


Monitoring Height of Relay Contact     [Back ]

See the Model 3560 Voltage Conditioner


Monitoring Compression Force in a Pill Press     [Back ]

See the Model 3570 DC Strain Gage Conditioner


Brake Testing     [Back ]

This system checks the output force of a brake booster for conformance to specification tolerances.  As pedal pressure is applied, the first Model 3570 DC Strain Gage Conditioner detects passage of a preset test-point value.  The "HI" limit output generated at this point is sent to the second 3570 as a logic "HOLD" command, thereby freezing the current brake force value.


Stress Analysis Using External Bridge Completion     [Back ]

See the Model 3570 DC Strain Gage Conditioner and the Model 10CJB-2 Bridge Completion Card.  In applications such as this, the lowest (2 V) excitation level should be used to help reduce gage heating effects.


Testing Motors for Proper Stall Torque     [Back ]

The Model 3570 DC Strain Gage Conditioner is set to capture the maximum motor torque by applying a PEK=ON command via the RS232/RS485 port—or via the rear Logic I/O Connector


Batch Weighing with Motor Control     [Back ]

By applying a TAR=ON command via the Model 3570 DC Strain Gage Conditioner's RS232/RS485 port—or via the rear Logic I/O Connector—an initial "auto-zero" can be performed, so that the weight of the container will be continuously "tared out" of the batch weight measurement.


Bearing Friction Testing     [Back ]

See the Model 3578 AC Strain Gage Conditioner
