Week #6 & #7: Eaton Sensor Handouts; 2, 3 & 4 Wire Sensors, other sensors.

Post by rjagodowski »

NOTE: This week a "Quiz Pack" is being distributed during the lab time with questions covering the Sensors Topics from the past several weeks. These quiz packs are customized with the the questions randomized for each student. See your instructor to pick up your copy. More information and a sample quiz pack can be found HERE.




Here is a catalog of Eaton Switches:

Note that this is different than the Sensor Learning Course we've been using which is attached below. This document is just to demonstrate the variety of styles available when selecting a limit switch.



This week we will continue working through the Eaton Sensors handout with Photo-Electric Sensors, and then our discussion will focus on 2, 3 & 4 wire sensors, sensor timing and time permitting, enclosure ratings.

Here's a link from Wikipedia on Retro-Reflectors, their construction and operation.

We'll also spend a bit of time discussing 2-wire, 3-wire and 4-wire sensors. You should view and work through each of the following tutorials. Some reinforce the content presented in the Eaton handout and other content is sensor related, but not in the Eaton pdf.

Two Wire Sensors
Three Wire Sensors
Four Wire Sensors

Sensor Wiring Configurations
PLC Sinking/Sourcing Input Modules
PLC Sourcing Input Modules
PLC Sinking Input Modules

Some miscellaneous Wisc-Online Tutorials:
Standard Sensor Transmission Signals Common analog sensor signal conventions using voltage, current & pneumatic pressure.

Sensor Output Timing Signals A good presentation of adjusting sensor outputs for On Delay, Off Delay and One-Shot outputs.

Inductive Proximity Sensors
Inductive Proximity Sensor Target Considerations

Hall Effect Magnetic Sensors These are faster than the Inductive Prox's discussed above.

Capacitive Proximity Sensors
Capacitive Proximity Sensor Target Considerations

Maximum Proximity Sensor Switching Speed

Excess Gain of Optical Sensors
Calibrating an Opposed Optical Sensor
Thru-Beam Photoelectric Sensors Some good information about how to properly align a Thru-beam emitter & receiver.
Retro-reflective Optical Sensors
Photoelectric Reciprocation Circuits This is a good tutorial to show ladders diagrams in action.

Ultrasonice Sensors While ultrasonic sensors were not presented in the Eaton Sensors handout, they are commonly used devices. This is a good presentation of the operation of ultrasonic sensors as well as the various type of analog signals found in industrial automation (0-10V and 4mA-20mA). Calibration of the zero and span adjustments of a 4-20mA sensor is also demonstrated.

Radiation Pyrometer Temperature Sensors Another topic not covered in the Eaton Sensors handout, this tutorial shows the fundamental operation of a Radiation Pyrometer, that is, non-contact temperature sensor which uses the Electro-magnetic waves emitted by an object to determine the temperature of the object.
