5. Water Level Pressure Transducer Simulation

Sensor: Submersible pressure transducer

Input: Precise excitation voltage 2.5 VDC

Output: Full bridge differential voltage, linear output, maximum negative

voltage equivalent to zero pressure, maximum positive output equivalent

to maximum pressure. Must calibrate in field to determine offset and

maximum and minimum pressures.
