Thermistors are ideal when measuring a single point temperature that is within 50°C of ambient.
If the temperatures are excessively high or low, a thermistor will not work.
Most thermistors work best in the range between -55°C and +114°C.
Sensitivity of thermistor is high.
Span value of thermistor is low.
A voltage dip is a short temporary drop in the voltage magnitude in the distribution or customer's electrical system.
Common causes of voltage sags and under voltages are short circuits (faults) on the electric power system, motor starting, customer load additions and large load additions in the utility service area.
Sags can cause computers and other sensitive equipment to malfunction or simply shut off.
