Molex Incorporated will showcase their customized capacitive fluid-level
sensors, a low-cost measuring solution with disposable sensors and reusable
electronic circuitry, at Molex booth #1983 at MD&M West Show, February 12-14,
Anaheim Convention Center, CA. Designed for measuring fluid or granular
material in non-metallic containers, the patent pending sensor electrode
design and configurable software provide higher accuracy with lower hardware
cost and easier installation.

“Many factors go into customer selection of fluid-monitoring equipment for
industrial and commercial processes,” states Steve Fulton, engineering
manager, Molex. “Capacitive fluid-level sensors solve the challenge of
detecting substances in containers for continuous and threshold measurement
without directly contacting the materials.”

Custom designed capacitive fluid-level sensors are optimized for medical fluid
management systems, automotive fuel tanks, agricultural fluid tanks, hydraulic
fluid and pump controls, beverage dispensing systems and other industry
applications. Featuring multiple output interface options, including SB, I2C
and discrete signals, the capacitive sensors provide a customized interface
for virtually any application requirement. The sensors deliver 95 percent
accuracy in auto mode and 98 percent accurate when manually calibrated. The
embedded software can be configured for maintenance-free auto-calibration or
manual calibration to maximize sensor accuracy.

Equipped with flexible circuitry which conforms to the container shape via
pressure-sensitive adhesive, capacitive sensors are easily mounted to the
outside of a container allowing measurement of caustic fluids, in addition to
granular and pulverized materials. The sensors can measure through almost any
non-metallic material. Featuring solid-state capacitive technology with no
moving parts, capacitive sensors eliminate problems with mechanical wear over
time. Providing design flexibility, sensor circuitry substrate options include
PCB, polyester flexible circuit and polyimide flexible circuit. A design can
use a traditional PCB for a flat surface container or a thin, flexible circuit
to accommodate curved surfaces or space-constrained applications.

The new fluid-level capacitive sensors can be mated with virtually any Molex
interconnect or cable assembly. They are fully compatible with integrated
designs using Molex customized user interfaces, including membrane switches
and capacitive touch technology. For additional information visit: To receive information on other Molex
