Unit 8 Lab Assignment

Recommended Materials

1. Lab Sheet
2. Pencil and Paper
3. EPT
4. Pressure Gage
5. Poly
6. Pneumatic Actuator 8-13 PSI
7. Electronic Controller 0-10 VDC

Scope

This lab will help the student to learn about the interaction of an electronic pneumatic transducer. Here you will calibrate the EPT.

Procedures

1. The instructor will give you the supplies needed for this lab
2. Read manufacture’s installation and maintenance manual
3. Connect the EPT to actuator, air supply, and electronic control
4. Following manufactures instructions you will proceed to calibrate the EPT to the actuator you are given
5. Adjust the controller to 0, 2, 5, 8, and 10 VDC on your lab sheet describe what happens to the actuator

Research Questions

1. At 5 VDC, what was the output in PSI?
2. At what VDC did the actuator become 100% open?
