Thermostats and thermal switches are electro-mechanical on/off switches that are activated by temperature changes.

Temperature instruments use contact or noncontact methods to measure temperature.

Analog panel meters measure and display processes and electrical variables with a simple dial display

Analog comparators are amplifiers that compare the magnitude of voltages at two inputs.

Digital-to-analog converter (DAC) chips convert digital signals that represent binary numbers into proportional analog voltages

Analog-to-digital converter (ADC) chips transform information from analog to digital form

Digital-to-analog converters (DAC) transform a digital number into a corresponding analog voltage or current
