Monitoring Motor Speed With Analog Output Application
A recent application required monitoring the speed of a motor. The customer, a motor testing facility, needed a device to display the motor’s speed in RPM, as well as provide a 4-20 output to chart the speed over a long period. An alarm was required to keep the operator from inadvertently running the motor too fast.
|
|
The PAXI0000 was selected to display the rate, the PAXCDL10 optional analog output card used to drive a chart recorder, and the dual alarm relay card for the over speed condition. To sense the motor’s speed, an LMPC0000, with the block mount 5400100, was selected to look at a keyway on the turning motor shaft.
All wiring must be according to the installation guidelines listed in the product’s specifications. For the setpoint outputs to function an external isolated voltage source (not shown below) must be connected in series.
