Thermistors - Protection study with polymeric PTC thermistors

Reading time: <1 minut The thermistor is a resistor whose resistance is strongly dependent on temperature, as a result having a nonlinear UI characteristic. The decrease or increase of the resistance is in close correlation with the type of thermistor, which can be with the negative temperature coefficient, NTC or with the positive temperature coefficient, PTC.

Sampling control systems

Sampling control systems - PID digital controller transfer function

Reading time: <1 minut In general, sampling means the discretization over time of a continuous signal. In most practical applications, the sampling is uniform (it takes place at equidistant time moments), and the discrete time signals obtained by sampling are also quantified (discretized in value), being therefore numerical signals.

Data acquisition and generation systems

Data acquisition and generation systems - Choice of sensors and transducers

Reading time: <1 minut Data acquisition systems are complex systems for monitoring processes in which, as a rule, several physical quantities are involved. They perform the sampling of analog or digital signals (depending on the nature of the translator), in order to store, transmit or process the acquired information.

Temperature sensors - Linearization of the temperature sensor characteristic

Reading time: 2 minute In the field of electrical measurements, the sensor means a device that converts a certain physical or chemical quantity into an electrical quantity, the latter being able to be used to indicate the value of the measured quantity or even to control the system that generated it.
