Question 1

Tolerance in most switches is about 2%; ____________________ is about 1%.

Accepted Answer

accuracy

Question 2

____________________ pressure sensors are the preferred choice because they can withstand higher overpressure and are more resistant to pressure spikes.

Accepted Answer

Ceramic

Question 3

In application, the pressure switch contact may be substituted for the limit switch contact.

Accepted Answer

Both pressure switches and limit switches are commonly used as safety devices in industrial applications. While they function differently (pressure switches activate when a certain pressure is reached, while limit switches activate when a certain position or movement is reached), they can often be used interchangeably in certain applications. Therefore, it is possible to substitute a pressure switch contact for a limit switch contact. However, it is important to ensure that the switch being used is rated for the specific application and that all safety standards and regulations are met.

Question 4

A pressure ____________________ utilizes semiconductor strain gauges that are epoxy-bonded to a metal diaphragm.

Accepted Answer

The answer of A pressure ____________________ utilizes semiconductor strain gauges...

Question 5

The pressure switch is used to transfer information concerning pressure to an electrical circuit.

Accepted Answer

The pressure switch is designed to detect changes in pressure and transfer this information to an electrical circuit. It is commonly used in various applications such as hydraulic systems, refrigeration systems, and air compressor systems.

Question 6

The ____ pressure switch is interchangeable with existing electromechanical pressure switches.&#10;A) sealed piston&#10;B) Bourdon tube&#10;C) diaphragm&#10;D) solid state

Accepted Answer

The solid state pressure switch is interchangeable with existing electromechanical pressure switches. The other options, such as sealed piston, Bourdon tube, and diaphragm pressure switches, are not necessarily interchangeable with existing electromechanical pressure switches.

Question 7

The ____ pressure switch consists of a disk with convolutions around the edge.&#10;A) sealed piston&#10;B) Bourdon tube&#10;C) diaphragm&#10;D) solid state

Accepted Answer

The diaphragm pressure switch uses a disk with convolutions around the edge, which flexes in response to changes in pressure. This movement is then used to actuate the switch.

Question 8

The ____ pressure switch can withstand large pressure changes and high overpressures.&#10;A) sealed piston&#10;B) Bourdon tube&#10;C) diaphragm&#10;D) solid state

Accepted Answer

Sealed piston pressure switches are designed to withstand large pressure changes and high overpressures due to their robust mechanical design, making them suitable for applications with demanding pressure conditions.

Question 9

With the use of programmable controllers in industry, the measurement of pressure has become much less important.

Accepted Answer

Programmable controllers may be able to automate processes, but the measurement of pressure is still very important in many industrial processes such as fluid handling, HVAC systems, and manufacturing processes. Pressure sensors are still commonly used in conjunction with programmable controllers to ensure safe and efficient operation of equipment.

Question 10

The ____ pressure switch is extremely sensitive. It senses peak pressures.&#10;A) sealed piston&#10;B) Bourdon tube&#10;C) diaphragm&#10;D) solid state

Accepted Answer

The answer of The ____ pressure switch is extremely sensitive....
