Laureate™ digital process and
strain panel meters are a cost-effective solution to a
wide variety of monitoring and control applications which
require a scalable readout from strain gauges or from
process signals such as 4-20 mA, 0-5 V or 0-10 V. They are
also ideal for use in potentiometer follower applications,
where the transducer output is a changing resistance.
