Application Examples of Laureate
Quadrature Meters & Transmitters
| Using Quadrature for Cutting to Length |
 |
Controlling the repetitive cutting of material to length is an excellent application of a Laureate quadrature transmitter or Laureate quadrature meter.
The quadrature encoder shares the shaft of a sensing wheel, whose rotation corresponds to lineal displacement of material. The transmitter compares the displacement reading against setpoint information, and then uses its dual relays to first slow down and then cut the material. |
| Using Quadrature for X-Y Positioning |
 | Accurate X-Y position or rate can be obtained from two shaft encoders, which convert linear position to quadrature signals as a shaft turns. In addition to serving as a transmitter, each Laureate transmitter or meter can use its optional dual relay setpoint capability for closed loop control. |
| Using Quadrature to Monitor a Drilling Operation |
 | Quadrature can be used to track position and vertical drilling speed of the bit in an oil drilling operation. A shaft encoder is rotated by a cable that moves with the drilling shaft. In this application, the same encoder signal is applied to a Laureate quadrature transmitter for position, and to a second quadrature transmitter for rate. Both transmitters can send a 4-20 mA signal to a control room and be alarmed.
In this application, quadrature provides much higher immunity to noise and jitter than a magnetic pickup. |
