HELPING YOU #MAKE SENSE OF SENSORS
EXAMPLE APPLICATIONS
TO ILLUSTRATE THE WIDE-VARIETY OF APPLICATIONS SOLVED USING CONTRINEX SENSORS, WE HAVE POSTED A LARGE SELECTION OF EXAMPLE APPLICATIONS WHICH CAN BE SEEN BY CLICKING ON AN IMAGE. BELOW ARE A SELECTION OF SOME OF THESE APPLICATIONS:
CUSTOMER VALUES
NO READJUSTMENT OVER TIME
NO WEAR AND TEAR AND RELATIVELY TAMPER-PROOF
LONG TERM RELIABILITY
NO MAINTENANCE
PRODUCT ADVANTAGES
EASY ADJUSTMENT/SETUP
LOCAL ANNUNCIATION (LED INDICATOR)
AFFORDABLE SENSOR WITH EXCELLENT RELIABILITY
A manufacturer of mobile cranes uses Contrinex 2-wire
inductive sensors to detect the position of stabiliser legs as
part of the vehicle safety system. Before the system will allow
the driver to drive the vehicle away, sensors confirm that
stabiliser legs have been retracted.
CUSTOMER APPLICATION
Mobile cranes, telescopic handlers and the like are equipped
with extendable stabiliser legs to prevent them from tipping
over when lifting. These stabiliser legs (or jacks) are
mechanical extensions of the chassis which widen the base of
the vehicle’s chassis to ensure its stability in all operating
situations. However, when the time comes to move the vehicle,
there must be verification that these stabilisers are fully
retracted. Either an indicator in the driver’s cab or a method of
disabling engagement of the vehicle’s transmission is used to
ensure safety and prevent drive-away accidents and damage.
The customer’s existing verification system relies on
mechanical contacts. However, the costs of maintenance and
replacements over the long lifetime of such vehicles are
relatively high and hence a non-contact solution was sought
.
Customer Solution
A normally closed, two-wire inductive sensor from Contrinex’s
Classic 600 Series was ideal for this application. Multiple
sensors (one for each stabiliser cylinder) are installed and
connected in a way that requires each sensor to be satisfied
that a target is either present or absent, thus completing a
logic circuit.
Initially, the simplest approach would seem to be to wire this
group of devices in series, as would be the case with
mechanical contacts. However, when using sensors, series
wiring presents the challenge of voltage drops. The customer
overcomes this by selecting 2-wire sensors with a ‘normally
closed’ output, then wiring them in parallel to create a logical
NAND situation.
This wiring solution resolves the issue and permits an easy to
implement, non-contact, non-mechanical approach to
providing feedback for the warning or inhibiting mechanism
of the vehicle.
