Hook up drawings meaning
They’re developing standards in areas as diverse as ensuring the safety of electrical equipment used in hazardous locations to cost-savings for interfaces between industrial process control computers and subsystems. Food, pharmaceutical and specialty chemical companies build factories with increasingly sophisticated computer-driven automation. The savings extend beyond the facility’s design, though. By using the batch standard, companies save as much as 10 to 15 percent off the typical cost of meeting Food and Drug Administration criteria for the reliability of automation equipment.
ISA has developed standards for the performance requirements of toxic gas detectors, standards to keep electrical equipment from igniting flammable material and standards to ensure safety at nuclear power plants. And some ISA standards can help an entire industry combine cost savings and safety.
But there is a hitch or, as the engineers might tell you, a “technical barrier to trade.
View PDF Drawing The main purpose of condensate pot is to catch and hold condensate and foreign material. The condensate may be drained from the bottom valve connection. Condensate chambers are used as a barrier between the main line and the secondary instruments in the measurement of steam or other vapors which condense to a liquid state insuring compatibility with the secondary instruments.
They can also be used to cool down very high temperature liquids. Seal pots are installed where the line fluid is corrosive or viscous to the extent where it cannot be permitted to contact the secondary instrument. Standard pipe sizes are 2″ to 6″. All Headers are Laser Marked, wherever possible. The following can be offered upon request. Typical industry applications include:
Analog and Digital Signals
Accountabilities Ensure safety and timely completion of projects. Ensure company Standards, specifications and procedures are followed in the execution of projects. Ensure cost saving in budgeting and projects are executed within the estimated time frame and cost.
Ensure that contractors comply at all times with safety rules, taking actions as required in case of disregards.
As you know good insulation has high resistance and poor insulation relatively low resistance. The actual resistance values can be higher or lower, depending upon such factors as the temperature or moisture content of the insulation resistance decreases in temperature or moisture. Remember that good insulation has high resistance; poor insulation, relatively low resistance. With a little record-keeping and common sense, however, you can get a good picture of the insulation condition from values that are only relative.
The Megger insulation tester is a small, portable instrument that gives you a direct reading of insulation resistance in ohms or megohms. For good insulation, the resistance usually reads in the megohm range. The Megger insulation tester is essentially a high-range resistance meter ohmmeter with a built-in direct-current generator. This meter is of special construction with both current and voltage coils, enabling true ohms to be read directly, independent of the actual voltage applied.
This method is non-destructive; that is, it does not cause deterioration of the insulation. Figure 2 — Typical Megger test instrument hook-up to measure insulation resistance. The generator can be hand-cranked or line-operated to develop a high DC voltage which causes a small current through and over surfaces of the insulation being tested Fig.

Hook-up drawing indicates tubing slopes, position of instrument in reference to process tapping point, scope break between instrument vs piping. Hook-up drawing also gives information the requirement of bulk material for each installation. It also details its specification size, type and material and the quantity. There are two types of hook-up drawing:
By mixing these two signals together out of phase, certain frequencies will be cancelled out, whilst other frequencies will be reinforced.
Instrument hook up diagrams isa standards During project construction phase, this drawing is also referred as a guidance of how to install the instrument properly. Hook-up drawing also gives information the requirement of bulk material for each installation. As stated earlier, information of the requirement of bulk material is stated for installation on each sheet hence the bulk material required for instrument hook up diagrams isa standards whole drawings could be summarized and tabulated in a document named Material Take Off.
Analog and Digital Signals Chapter 9 – Electrical Instrumentation Signals Instrumentation is a field of study and work centering on measurement and control of physical processes. These physical processes include pressure, temperature, flow rate, and chemical consistency. Due to the fact that electrical quantities of voltage and current are easy to measure, manipulate, and transmit over long distances, they are widely used to represent such physical variables and transmit the information to remote locations.
A signal is any kind of physical quantity that conveys information. Audible speech is certainly a kind of signal, as it conveys the thoughts information of one person to another through the physical medium of sound. Hand gestures are signals, too, conveying information by means of light.
Hook-up drawing also gives information the requirement of bulk material for each installation.

We need to connect musical instruments to our church sound system, how should we do this? A musical instrument such as an electric guitar or electronic keyboard uses a High Impedance, Unbalanced output. This is designed to operate effectively up to 15 or 20 feet without picking up hum and electrical or radio interference. This cable must be a shielded instrument cable. Don’t try to use an unshielded speaker cable.
Uo of these conveniences are the result of a standard, a set of characteristics or quantities that describes features of a product, process, service, interface instrument hook up diagrams isa standards material.
I have worked both sides of the fence her both as a client rep and as the engineering contractor’s rep. Most sub contractors are quite happy to do installation work all day long but when you make them responsible for loop checking the can be at times, a bit reluctant to ‘think’ for themselves, especially when it comes to look checking as they then have to go and hire techs etc who then need to be told what to do.
Construction work is all about creating extra’s to earn more dollars for work supposedly not included in the scope. A bad scope of work which does not detail what is expected of the contractor when it comes to loop checking including details of loop folders, cal sheets etc is another reason for him to sit back and not complete his side of the contract. That generally works best. The installer is more conscious of maintenance friendly installations because they know another company will be going through their work before it is “turned over.
The will generally ensure potential issues are pointed out because it brings attention to that fact that their paycheck was worth it, and they may also get the remediation work, which is an “extra” and puts extra money in their pockets in a few ways.
