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 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 circuit probe detection, are incorporated within the device.
A second linear input for alternative sensor signals
may also be selected.
Features
Y Selectable thermal-resistance or linear probe inputs
Y Control circuitry for thermal-resistive probe
Y Single-shot or repeating measurements
Y Switch on reset and delay to avoid transients
Y Output amplifier with 10 mA source and sink capability
Y Short or open probe detection
Y a50V transient protection on supply and control input
Y 7.5V to 18V supply range
Y Internally regulated supply
Y b40§C to a80§C operation
