3.1 Electrical Specifications
An electrical voltage output indicates flow above (5 V) or below (0 V) the
inside the sensors flow
calibration for other media is available on request-
Table 3: DC Characteristics.
3.2 Electrical Connector and Pinout
Connector type on PCB: 5 pin Molex PCB Header 53261-0590. Mating connector: Molex 51021-0500.
3.3 Mechanical Specifications and Pressure Rating
Inside the LG01 flow sensors a highly sensitive microsensor-chip is mounted on the outside of a straight glass
capillary and allows to measure the flow through the wall (US Patent 6,813,944 B2) using a thermal principle.
