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 – – – – – – 0 1 -5 0 4 -10 to to to to to to 10 V 5V +5 V 20 mA 20 mA +10 mA Sensors and sensor systems with standardised signal output, e.g. RS-232-C, RS-422-A, RS-485 or with data bus interfaces such as field bus (Profibus, sensoractuator-bus). © Festo Didactic GmbH & Co.
