An electronic tachometers are used as a sensor that reads a magnetic strip and reports the rpm digitally. It is capable of producing mean readings rotational speed on components whose rpm is fluctuating. It is used as a velocity transducer for the track-accessing control system of a disk file is described. Rather than employing a conventional moving magnet and fixed-coil velocity transducer, this electronic tachometer combines information from the servo head position signal and from the actuator motor current to generate an accurate measurement of actuator velocity.

Electronic Tensiometers are portable pressure sensors for measurement of the soil. This tensiometer is ideal for automatic soil moisture measurement and suitable for soil, peat and other medium. They are compatible with skye datahog loggers and hydrosense meters. Electronic tensiometers are used to monitor cable tension.

Electronic thermostats use thermistors as their temperature-sensing element. The most modern electronic thermostats use internal microprocessor and non-volatile EEPROM memory to store and execute program instructions. It also has internal software that prompts the installer or occupant for information through a liquid crystal display. It draws very low operating power from the 24 VAC transformers in the controlled device. This allows for both power supply and on/off control through a single pair of wires.

Electronic Throttle is an automobile technology that serves the mechanical link between the accelerator pedal and the throttle. It determines the throttle position by calculations from data measured by other sensors such as an accelerator pedal position sensor, engine speed sensor and vehicle speed sensor. The electric motor within this is then driven to the required position via a closed-loop control algorithm.

Electronic timed drain is ideal for protecting surge or compressor tanks. They also include 6' power cord.

Electronic timer is a type of electronic circuit to accomplish a time delay. They have better accuracy, are less expensive, can be set for a greater range of time delays. Some electronic timers use a basic RC time constant and others contain quartz clocks and integrated circuit timers. Many of these timers can be set for time delays with an accuracy of 0.01 second. Electronic timer can be classified broadly into two major groups as RC elements and digital timers based on the type of timing element used.
