70% to passFor a pneumatic transmission system for instrumentation and control purposes, what is a common industry standard for pneumatic signal pressure range?
A0 to 10 psig
B0 to 100 psig
C3 to 15 psig
D3 to 150 psig
AI Explanation
The correct answer is C) 3 to 15 psig. This is the common industry standard for pneumatic signal pressure range in instrumentation and control systems. This pressure range is widely used because it provides a reliable and consistent signal transmission, and is compatible with a variety of pneumatic instruments and control devices. The other answer choices are not the standard pressure range - 0 to 10 psig (A) is too low, while 0 to 100 psig (B) and 3 to 150 psig (D) are significantly higher than the typical 3 to 15 psig range used in most pneumatic instrumentation and control applications.
