Digital Linearized Temperature Indicator

Description :

Thermocouple sensors generating emf/mV and RTD sensors generating the change in resistance value with respect to the change in temperature does not have non linear characteristic, hence to indicate the temperature within the accuracy of 0.1 oC or 1 oC throughout the measurable range, the need arises to linearize these non linear curves. 
Libratherm offers various models of Linearized Temperature Indicator / Controller for accurate indication of temperature within the accuracy of ± 1oC or ± 0.1oC in spite of non-linear behavior of the thermocouple and RTD (Pt-100) sensors. The Linearized indication is achieved by software linearization technique using 12 bit ADC and high-density memory, where the data’s are stored in. Along with the digital Linearized indications, single or dual set point control is also available. The Control action may be ON/OFF (through Relay/SSR/Triac). One of the application areas of this controller is to use it as the safety controller (or police protection) along with the microprocessor based PID or RAMP/SOAK program controller, where the indicating accuracies of both are matched without any ambiguity.

Features :
• Accuracy better than ± 0.1 % of the full scale.
• Elegant looks and Very easy to operate.
• Digital design and not prone to EMI/RFI.

Application :
• Heat treatment
• High temperature Furnace / Kiln control
• Star / Delta change over of heating coils
• Police protection with PID/Program controller
• Metallurgy and Ceramic R & D centres.
