LM1042 Fluid Level Detector

The LM1042 uses the thermal-resistive probe technique to measure the level of non-flammable fluids An output is provided proportional to fluid level and single shot or repeating measurements may be made All supervisory requirements to control the thermal-resistive probe including short and open circ.
