A safety interlock is a normally open valve that closes in the event of a process upset. Usually it is attached to electronics that perform logic operations on process conditions, and only trips (closes) in the event that exceeding those conditions will cause harm to equipment or personnel.

How does interlock mechanism work on a multi rail gear selector?
It is a safety device that prevents selecting two gears at the same time. If that happened the gearbox would be destroyed.
Can you describe shielding and grounding for electronic instrumentation?
The purpose of shielding is to reduce or eliminate noise currents from coupling into electrical measurements. It surrounds the electrostatic shield, protecting the instrument user from hazardous voltages. Instrumentation is safety grounded at the power inlet, ensuring that the metal instrument enclosure is always safe to touch.
How long must records of process safety analysis be kept?
for the life of the process
What is process control and instrumentation?
the field of proces control en instrumentation deals with monitoring process parameters en adjust the process (control) based on that information. instrumentation is required to monitor and control the process, and varies from process to process
How is applied electronics and instrumentation course different from instrumentation and control?
mainlyelectronics and instrumentation deals with the electronics based instruments and process controlling of those connected to a process e.g : plc dcs and scada but instrumentation and control are concerned with the control system and the process loop modelling e.g: power drives , linear and non linear control system
Does cruise control work while the car is in reverse?
no it is has a safety interlock to prevent activation.

What is a Safety interlock switch?
Switch that prevents gear shift lever from moving from "Park" position until brake is applied
What is Virtual Instrumentation?
Virtual instrumentation refers to the process of using customizable software and modular measurement hardware to create user-defined measurement systems. Today virtual instrumentation solutions are used in a number of industries including automotive, oil and gas, and electronics.
How do you bypass the parking brake for an after-market in-dash DVD player?
Disabling the parking brake interlock for in-dash DVD players is against the law in many jurisdictions. The interlock is there as a safety feature and should not be adjusted in any way. The interlock is a safety feature to avoid distracting a driver while driving. However in some older vehicles it is necessary to attach the parking brake wire to a switch to ground. The switch is to maintain legality as one cannot watch a movie while driving.
