Thermocouple sensors generating emf/mV and RTD sensors generating the change in resistance value with respect to the change in temperature does not have linear characteristic, hence to indicate the temperature within the o o accuracy of 0.1 C or 1 C throughout the measurable range, the need arises to linearized these non linear curves.
Offers various models of Linearized Temperature Indicator/Controller for accurate indication of temperature within the accuracy of ± 1 C o or ± 0.1 C in spite of non-linear behavior of the thermocouple and RTD (Pt- 100) sensors.
The Linearized indication is achieved by software linearization technique. Along with the digital Linearized indications, single or dual set point control is also available. The Control action is ON/OFF type (using Relay/SSR/Triac). One of the application area of this controller is to use it as the safety controller (or police protection or redundant control) along with the microprocessor based PID or RAMP/SOAK program controller, where the indicating accuracies of both are matched without any ambiguity.
