Pharmacode, also known as Pharmaceutical Binary Code, is a barcode standard, used in the pharmaceutical industry as a packing control system.
PID loop
An I/O element used to drive an analog input toward a particular value (called the setpoint) and to keep the input very close to that value. PID loops include a gain term (abbreviated P for proportional, which is the inverse of gain), an integral term (I), and a derivative term (D). Temperature control is a typical application for a PID.
Pillow block
A bearing block or housing having a flat mounting surface offset, but parallel to the shaft.
Pinch point
Any point on a mechanical system where the relationship of powered moving pieces is such that the spacing between them changes and could cause any part of the human anatomy to be caught between them. The spacing may decrease to a fraction of an inch, which could pinch a finger or decrease to several inches, which could still pinch a human knee or head.
See Programmable Logic Controller.
See Programmable Limit Switch.
A variable resistor often used to control a circuit. 2. A balancing bridge used to measure voltage.
Power supply
A separate unit or part of a circuit that supplies power to the rest of the circuit or to a system.
Powered feeder
A driven length of belt conveyor, normally used to move product horizontally onto an incline conveyor.
Pressure roller
A roller used for holding the driving belt in contact with the load carrying rollers in a belt drive live roller conveyor.
Pressure sensitive label (PSL)
Pressure sensitive labels (PSL) are labels which form a bond when pressure is applied to marry the label with the product. No solvent, water, or heat is needed to activate the adhesive.
Primary axis
The axis along which the transducer is designed to be loaded; normally its geometric centerline.
An opportunity for improvement or undesirable condition, often manifested by symptoms, created by root causes which must be systematically identified and eliminated to control the problem.
Step-by-step tasks which are necessary to meet standards; a method or manner of proceeding. How to meet standards.
A systematic and defined method of doing something. A process generally involves a number of steps or operations. The combination of people, machine and equipment, raw materials, methods, and environment that produces a given product or service.
Process automation
Process automation involves the process of supplementing and manual process with an automatically controlled alternative, with the aim of reducing costs and increasing consistency. Typically utilizes custom automation equipment or an automated system.
Process control
Automatic monitoring and control of a process by an instrument or system configured or programmed to respond appropriately to process feedback.
Process management systems
The process management system is the system of processes that are designed and delivered to support the quality integrated system.
Process simulation
Use of a mathematical model by a computer program to implement different process design scenarios with real-time feedback.
Product stop
A mechanical barrier to interrupt the flow of product on an active conveyor, that is, without shutting down the conveyor. Typically, a product stop is pneumatically actuated. Also known as Case Stop.
Production control
Systematic planning, coordination and direction of all manufacturing activities to ensure that products are made on-time, of adequate quality, and at reasonable cost.
Production startup
The point during a project where the production system has been installed, all buyer's production people have been trained and the system begins running production on a standard factory order under standard production controls.
Sometimes called affectivity. The product of efficiency and utilization.
Vendor-independent open fieldbus standard for use in manufacturing and building automation as well as process control. Utilizes a non-powered two-wire (RS485) network. PROFIBUS is standardized under the European Fieldbus Standard EN 50 170. Includes 3 versions - FMS, DP and PA. Visit for more information.
Programmable Limit Switch (PLS)
The basic purpose of a limit switch is to switch discrete outputs on or off based on the position of a rotating shaft. The points at which an output switches on or off, called setpoints, are defined by the person who sets up the machine. In an electronic limit switch system, the cam shaft is replaced by a rugged position sensing transducer. The Limit Switch Controller uses this transducer to determine the position of the shaft. The Controller then compares this position to its programmed setpoints and determines if its outputs should be on or off.
Programmable Logic Controller (PLC)
1) A class of industrially hardened devices that provides hardware interface for input sensors and output actuators. PLCs can be programmed using "relay ladder logic" to control the outputs based on input conditions and / or algorithms contained in the memory of the PLC. 2) A device that is pre-programmed to accept relay ladder logic instructions and perform these instructions to control the equipment operation.
Programmable Read-Only Memory (PROM)
A type of ROM that can be written (programmed) with a device programmer. These memory devices can be programmed only once, so they are sometimes referred to as write-once or one-time programmable devices.
Projected life
The estimated useful period of a resource or system, based on time, number of cycles, units processed, or other factors.
Proposal, budgetary
A dollar value response solicited by the buyer and given by the builder, normally used as an item for the buyer's capital budget. It is not binding upon the builder.
Proposal, firm
The builder's detailed, accurate response to a buyer's RFP (request for proposal). The builder responds expecting to be bound by the proposal to furnish the goods for the price stated.
An agreed set of rules to allow data to be transferred among systems.
A functioning version of a product or process, or a portion of a product or process, intended to prove a principle to  be the basis for further experimentation. A prototype is not intended to be used as part of a salable product or system.
Prototype tooling
