Buyer
Beware!There are sensor manufacturers, sensor distributors,
sensor applications engineers, sensor salesmen, sensor reps, sensor resellers
and system integrators who build sensors into larger systems. They are not all
the same, do not all have the same education, experience and know-how. Some are
sensor experts; some know a little. Some know less than a nearby rock about the
sensor they represent or provide. The balance occupy all shades in between the
limits. Some vendors are more honest
than others, just like in every business. The watch words are, as always: "Buyer
beware", until you build up confidence in their business ethics and technical
abilities (and that of the organisation they represent). Fortunately
contact sensors are relatively mature technologies for most of products used in
large volume. There are standards for composition, calibration and use limits,
connectors and so on. View our Standards pages to learn
more specifics. Not everything is covered. You need to have someone you can trust
or an in-house specialist who is up to date on these items plus stays aware of
the advances in them when you go to purchase them. Make
sure that your measurement requirements are as complete and detailed as possible;
always reference any applicable standards and require certified compliance to
them. |
