Circuit for inductive sensors and method for its use |
摘要 |
Circuit arrangement for a number of inductively operating sensors (L1-L4) has control (13) and evaluation means for the sensors and sensor signals. The control means are connected to the sensor via MOSFET switches (S1-S4) with low drain-source resistance. The invention also relates to a corresponding method for control of the MOSFET switches in which the gate control voltage is regulated so that a frequency is output that is constant over a temperature range. |
