Simarine SI-TPS-02 0-1m Water Tank Pressure Sensor marine 4" speakers The only difference is impedance:Designed to Work With High Performance Pressure Senders Enerdrive SI TPS is from a series of High Performance compact pressure senders. These transmit by using a ASIC signal conditioning chip and dry ceramic capacitive pressure sensor. it has features of anti corrosion, anti wear, shock resistance and vibration resistance. In addition to the general range of sensors, it's most outstanding characteristic is the positive and negative gauge pressure
