Fluid Level Detector - National Semiconductor

The LM903 uses the thermal-resistive probe technique to measure the level of nonflammable fluids. A low fluid level is indicated by a warning lamp operating in continuous or flashing mode. All supervisory requirements to control the thermal-resistive probe, including short and open circuit probe detection, are incorporated within the device. The cir- cuit has possible applications in the detection of hydraulic fluid, oil level, etc., and may be used with partially conduct- ing fluids. By National Semiconductor Corporation
