The maximum frequency that can be transmitted is a function of the ratio of peak signal voltage to the current provided by the signal conditioner and the total cable capacitance. The calculators on this page assume a 5 V peak output from the sensor and 1 mA current used to power sensor electronics, both typical of most ICP® sensors.
| Where: | |
| fMax = Maximum Frequency (Hz) | |
| C = Cable Capacitance (picofarads) | Length x cap/ft |
| V = Maximum output from sensor (volts) | 5 V in most ICP systems |
| IC = Constant current from signal conditioner (mA) | Standard allows for 2 to 20 mA. 1 mA is subtracted for powering internal electronics |
| 109 = Scaling factor to equate units | |
Typically, the equation is solved for maximum frequency or for maximum allowable cable length. Cable selection allows for slightly different capacitance.
