The P330 is a 4-channel benchtop/rackmount simulator of capacitive fuel or oil liquid level sensors. Each independent, isolated channel can simulate both the resistive and conductive components of a coaxial level sensor. The values are simulated electronically with 16-bit resolution, and are monotonic and glitch-free programmable within each impedance range. Interface is USB and Ethernet. The P330 measures and reports realtime excitation voltages and frequencies, can simulate sensor faults, and includes LED indicators and BIST.
