Varies

Description
- An electrical circuit in which two circuit branches (usually wired in parallel with each other) are bridged by a third branch. The most common type, a Wheatstone bridge, contains four resistors: two of known values, one which is variable and calibrated, and one whose resistance is to be determined. The circuit is subjected to power and hooked up to a galvanometer. The variable resistor is then changed until the galvanometer reads zero. It is then determined that the ratio between the variable resistor and its known neighbor is the same as the ratio between the unknown resistor and its known neighbo.

The slower the rise, the larger the capacitance. For additional accuracy, the capacitor can be placed into a bridge circuit. Many also measure leakage, equivalent series resistance (ESR) and inductance.

Description
- A passive, two-terminal electronic device which stores electrical energy. The capacitor consists of two conductors, often in the form of metallic plates, foil, thin film, bead of metal or electrolyte, separated by a dielectric medium, such as glass, ceramic, plastic, paper, or mica. When the two conductors experience a voltage difference, an electric field is created across the dielectric with a positive charge collecting on one conductor and a negative charge collecting on the other. This charge can then be manipulated or used at a later time.

Resistance

Description
- An electronic device which measures the equivalent series resistance (ESR) of real capacitors, without the need to disconnect the capacitor from the circuit it is connected to. The meter operates by discharging a real electrolytic capacitor and passing an electrical current through a short time.

As wind moves past the anemometer, the cups spin at a rate proportional to the wind velocity. By counting the number of times the cups spin in a set time period, wind velocity can be determined.

Common Uses
- Measuring the velocity of air moving past a certain point, such as in weather forecasting or on an airplane.

Common Types
- Velocity Anemometers (Cup, Vane, Hot-Wire, Laser Doppler, Ultrasonic, Acoustic Resonance)
- Pressure Anemometers (Plate, Tube, Pitot Tube)

Melt Flow Rate

Description
- A device used to measure the flow rate of the melt from a thermoplastic polymer. The device operates by placing a small sample amount of the material into a shaft. A heated tube with a calibrated weight is then brought into the shaft. The melted sample material is then forced through a calibrated die (typically 2 mm in diameter) while the unit measures the mass of the material to pass through the die.

Common Uses
- Measuring the rate at with a thermoplastic polymer melts, done to help choose a material that can be easily formed into the intended shape, without sacrificing its mechanical strength.

Inside Diameter (in, cm)

Description
- Typically in a set, it consists of a spring loaded plunger with a handle attached that has a knurled lock at the end. The gage is inserted at a slight angle to the bore and gently locked to a size slightly larger than the bore while at that angle. Then, rocking the handle side-to-side, slowly move the handle across the bore to the other side. The rocking will first align the gauge with the bore axis and the act of moving the handle to the other side of the bore will bring it to the exact bore diameter. The gage is then removed and measured with a micrometer or caliper.

Concentricity

Description
- A benchtop measuring device containing an indicator on one end and a device for holding a round object on the other. The tip of the indicator is placed on the round object having its concentricity checked.

Checking concentricity is quite difficult and is reserved for high-precision parts, where checking for run-out is not sufficient enough.

Common Uses
- Determining the concentricity of a machined cylindrical or spherical part where these tolerance are extremely tight, such as a piston head.

RF Impedance

Description
- An electronic device which measures the quality factor of a radio frequency (RF) circuit (the amount of energy dissipated per cycle in a non-ideal reactive circuit). The meter contains a tuneable RF generator with a very low impedance output and a very high impedance input. A precise capacitance is applied to the circuit and the voltage developed across the system is measured by the detector. Comparing the ratio of the developed RF voltage to the applied RF current, along with the known reactive impedance, determines the Q factor. Q meters have largely been replaced by other instruments.

Thickness
Film Thickness

Description
- An electronic device used to measure the thickness of a wall or a coating on a manufactured part without requiring access to both sides of the test piece. It contains a transducer connected to base unit, which contains the microprocessor and display.

Description
- A widely-used device which measures temperature, by converting temperature change into mechanical displacement. The thermometer consists of two strips of dissimilar metals (typically steel and copper or brass), joined together, side-by-side.

As the strip bends, it moves a needle, which points to a calibrated scale on the display of the thermometer, providing a temperature readout.

Common Uses
- Quick, inexpensive temperature measurement in many applications, such as in water, fluids, gases, ovens, kilns, furnaces and freezers.

Temperature

Description
- An electronic device which measures the temperature of an object from the thermal radiation emitted by it. The lens is focused on the object being measured (often through the aid of a laser for accurate aiming).

Measurement Parameter

Temperature

Description
- Similar to a thermocouple, is a sensor used to measure temperature. Most commonly, it is an element consisting of a length of wire, typically platinum, nickel or copper, wrapped around a ceramic or glass core. These metals are chosen due to their consistent resistance versus temperature relationship. As the measured resistance of the probe changes, the device it is used in conjunction with senses this change and provides a readout of the corresponding temperature. An RTD probe is very similar to a thermistor, with the exception that an RTD probe uses pure metals.

Common Uses
