PCBA count sensor is based on WF8002 Metering Chip. The coils are integrated into PCB board , it used to detect the circle numbers of metal plate which is below PCB coils in proper distance. it is widely applied in water meter/gas meter industries.Unique Metering Algorithm/lnti-magnetic/Extremely low power consumption/durable/reliable/compact/customizable are highlights of PCBA count sensor.
(1)Signal output mode--standard pulse output (including forward running and reverse running)
TTL/OC output mode,other mode could be customized.
(2)Power Supply-Rated voltage: 3.0V~3.6V.
It is external power supply,The higher power supply voltage is, the longer detect distance would be.
Residential Meter: smaller than 6uA;
Commercial Meter: smaller than 20uA
The longest stable work distance between 304S/S rotor and PCBA sensor. Diameter 16mm、0.2mm thickness is the normal size of 304S/S rotor.The bigger diameter of 304S/S rotor is, the farther work detect distance could be.
Metal Rotor and PCB sensor’s flat must be concentric/at the same axis and parallel on a stable holder.
