Platinum and Nickel Probes

These probes are assembled with RTD's on which leads
are welded These RTD's have a low ohmic value
(see corresponding heading) and the lead length
presents a resistance in serie with the sensitive
element which harms the measurement accuracy.

To avoid such reaction, 3 or 4 leads are used so as to separate
the measurements leads from the feeding leads, thus, the
measurement leads will not be supporting a current and their
own resistance will be negligible.

Probes with Platinum or Nickel sensors are connected to
electronics for measurement, data or automation by means
of a 4-20 milli Amp. Transmitter (the most suitable solution)
or a 0-10 V. or 0-5 V. voltage transmitter.

It is strongly advised to place the transmitter as closed as
possible from the sensor to avoid RFI in the leads

Sensors ands leads junction are encapsulated in housing
(box or tube) for which shape and materials are adapted
to the needs, in view to protect the sensitive part
against dusts, moisture, shocks.

Tubes are made of metal : Stainless steel, tinned or
nickel platted copper, brass, bronze anodised aluminium,
or of plastics : PVC, Teflon, Vinyl, Silicone, Poly carbonates etc.

Leads and cables can be insulated with PVC, Silicone,
Teflon, Polyurethane, Vinyl, Isomid, Kynar, Glass, Silk Jacket etc.

Lengths are from some centimetres to several metres.

The other end of cables can be stripped, stripped and tinned,
fitted with fast-on or connectors.

Boxes are made of plastics : PVC, ABS, Poly carbonates, or of metals
(steel, Stainless Steel, Aluminium or other. Frequently they have a
spherical shape, designed under the name of connecting head

All probes are customs designed.
