Resistive temperature transducers
Resistive temperature transducers made of platinum and copper are used for temperature measurements and control in liquid, solid, gaseous and granular environments for various industrial applications.
For the purpose of temperature measurements performance in addition to primary transducers (resistive temperature transducer) a measuring module is also required. Resistive temperature transducer together with measuring module form intelligent temperature sensor which transfers the measured temperature value. Intelligent temperature sensor can be used both for temperature measurements and control as well as for constant / long-term temperature data registering. Thus, the measuring system enables a wide range of possible applications for temperature measurements, registering and control in various conditions and environments.
