 | Overview The BL310C capacitive input type liquid level gauge is based on the principle that the measured liquid static pressure is proportional to the height of the liquid. It uses advanced isolation type diffusion silicon sensitive elements or ceramic capacitive pressure sensitive sensors to convert static pressure into electrical signals, which are then temperature compensated and linearly corrected to convert into standard electrical signals (generally 4-20mA/1-5VDC). It is a widely used level gauge in mechanical engineering and automation control, which can be connected to meter heads, recorders, computers, PLC program controllers or alarms. |
