Documenting skills is value-add
ISA certification provides an objective, third-party assessment, and confirmation of a person's skills. It gives manufacturing and factory staff the opportunity to differentiate themselves from their peers and gain recognition. InTech covers three certification areas in its monthly Certification department.
ISA Certified Automation Professional (CAP) program
Certified Automation Professionals (CAPs) are responsible for the direction, design, and deployment of systems and equipment for manufacturing and control systems.
The following question comes from the CAP study guide, Performance Domain II, Definition: Identify customer requirements and complete high-level analysis of the best way to meet those requirements
Which of the following contract types places the PRIMARY risk with the supplier?
A. Cost plus
B. Fixed price
C. Time and material
D. Unit price
The correct answer is B, fixed price.
The supplier estimates a fixed-price contract, and the customer accepts it and agrees to it before the project begins. Any overruns are the responsibility of the supplier.
In cost plus, time and material, and unit-price contracts, the supplier and customer agree on the margin-not the total cost of the project.

Certified Control System Technicians (CCSTs) calibrate, document, troubleshoot, and repair/replace instrumentation for systems that measure and control level, temperature, pressure, flow, and other process variables.
This question comes from the Level I study guide, Domain 3, Troubleshooting. Level I represents a professional who has a five-year total of education, training, and/or experience.
The Coriolis effect is associated with the:
A. Head meter
B. Mass flowmeter
C. Positive displacement meter
D. Turbine meter
Using the Coriolis effect that causes a laterally vibrating tube to distort, a direct measurement of mass flow is obtainable using a Coriolis flowmeter.
Furthermore, a direct measure of the density of the fluid is also possible.
Coriolis measurement can be very accurate irrespective of the type of gas or liquid that is measured; the same measurement tube works for hydrogen gas and peanut butter.
The correct answer is B, mass flowmeter.
Certified Industrial Maintenance Mechanics (CIMMs) are responsible for preventive, predictive, and corrective maintenance. They are multi-skilled individuals whose expertise is primarily mechanical in nature as opposed to instrumentation or electrical.
CIMMs have a minimum of five years of relevant work experience in the maintenance mechanic field or three years experience and a two-year associate degree in maintenance or a related field. This question is from Performance Domain III: Troubleshooting and Analysis.
A P&ID needs to be updated when:
A. A change is made to process equipment
B. Corrective maintenance is performed on process equipment
C. Preventive maintenance is performed on process equipment
D. A new model of process equipment is manufactured
The correct answer is A, a change is made to process equipment.
As changes and modifications are made to process equipment, piping and instrumentation diagrams (P&IDs) must be updated.
Without P&ID changes, further modifications or improvements would be incorrect, and maintenance mechanics would not have the correct information to properly perform their work.
