LM903 Fluid Level Detector
General Description
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.
