Not sure what cavitation and viscosity have to do with your lab equipment? Time for a refresher on your terminology?
See our list of common terms used for electrical, pressure, electrochemistry, and lab instruments and processes.
Absolute pressure (psia): The total force per unit area exerted by a fluid. It is the sum of atmospheric and gauge pressures.
Buffer: In chemistry terms, a solution that maintains a set pH value regardless of added acids or bases; often used for calibration.
Cavitation: Process in which small bubbles are formed and implode violently. This results in aggressive cleaning action in ultrasonic cleaners.
Convection: Transmission of energy or mass in a medium by movement of the medium itself.
Density: The mass of a given substance per unit volume, often expressed as pounds/ft3 or grams/cm3.
Direct current (DC): A current with a constant polarity.
Explosion-proof (XPRF) motor: A totally enclosed motor that will withstand an explosion of a specific vapor or gas within its housing, or will prevent sparks or flashes generated within its housing from igniting surrounding vapor or gas.
Gauge pressure (psig): A measure of the force per area exerted by a fluid using atmospheric pressure as a zero reference.
Impedance: The opposition in an electric circuit to the flow of an alternating current. It consists of ohmic resistance, inductive reactance, and capacitive reactance.
LIMS (Laboratory Information Management System): A system that manages operations of a testing laboratory
Open drip-proof (ODP) motor: An open motor with ventilator openings that will prevent liquids and solids, dropped from an angle of 0° to 15° from vertical, from interfering with its operation.
Proportional control: Control in which the amount of corrective action is proportional to the amount of error.
Range: The limits within which a device or circuit operates or the distance over which a transmitter operates reliably.
Serial transmission: Sending one bit at a time on a single transmission line.
Temperature compensation: Correction for the influence of temperature on a measurement.
Transducer: Any device which generates an electrical signal from real world physical measurements.
Transmitter: A device which translates the low-level output of a sensor or transducer to a higher level signal suitable for transmission to a site where it can be further processed.
Three-phase motor: A relatively inexpensive, self-starting motor (no starting winding or capacitor); can start heavy loads. The motor requires a three-phase AC power supply.
Viscosity: The resistance of a fluid to flow when subjected to shear stress.
