Steam traps are automatic valves that release condensate from a steam space while preventing the loss of live steam. They also remove air and noncondensables from the steam space.

Fixed gages are designed to access a specific attribute based on comparative gaging

Fixed mount bar code scanners are designed to manually or mechanically read items passed by their scan windows. Unlike hand scanners, they are affixed to a single location

Fixed growth treatment systems attach microorganisms to a surface that is exposed to water

Oscillators are devices that are used to generate repetitive signals. They produce output signals without an input signal. There are two major types of electronic oscillators: harmonic oscillators and relaxation oscillators. Harmonic oscillators produce sine wave outputs. Relaxation oscillators produce non-sine wave outputs such as square wave, rectangular wave, and sawtooth outputs.

Resonators are frequency-selective electronic circuits that can produce a fixed (resonant) frequency when properly excited. The value of the resonant frequency depends on the circuit’s components (e.g., inductors, resistors, capacitors, crystals, etc

Spectrum analyzers and signal analyzers display raw, unprocessed signal information such as voltage, power, period, wave shape, sidebands, and frequency. They can provide the user with a clear and precise window into the frequency spectrum.

Digital dividers are integrated circuits that divide the frequency of an input signal by a divisor value.

Phase-locked loop (PLL) frequency synthesizers are electronic devices that produce frequencies coherent to a reference frequency.

Ceramic capacitors have a dielectric made of ceramic materials.

Fiber optic attenuators are devices that reduce signal power in fiber optic links by inducing a fixed or variable loss. They are used to control the power level of optical signals at the outputs of light sources and electrical-to-optical (E/O) converters. They are also used to test the linearity and dynamic range of photo sensors and photo detectors

Message LED displays are typically commercial or industrial signs. They allow for larger characters and longer viewing distances than their smaller digital cousins.

Resistors and potentiometers are passive electronic components that oppose the flow of either alternating current (AC) or direct current (DC). 

Crushers and mills are used to reduce chemicals, materials or other products to a desired particle or aggregate size range.

Signal generators and waveform generators are used to test and align all types of transmitters and receivers, to measure frequency and to generate a signal, waveform or noise source. Signal generators can use AC energy, audio frequency (AF) and radio frequency (RF) to function.
