only by using additional circuitry.
Examples – Piezoresistive or piezoelectric sensor components
– Pt-100- or thermoelectric cells
– Magnetoresistor and Hall sensor components
– pH- and conductivity measuring probes
– Linear potentiometer These are often applications where, in the case of high production, the user chooses
his own electronic solutions. Type D Sensors with analogue output and integrated amplifier and conversion electronics
providing output signals which can be immediately evaluated.
Typical example of output signals Type E 14 –
