LM1042 Fluid Level Detector
General Description
The LM1042 uses the thermal-resistive probe technique to
measure the level of non-flammable fluids. An output is pro-
vided 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 circuit probe detection, are incorporated within the de-
vice. A second linear input for alternative sensor signals
may also be selected.
