DESCRIPTION:

Libratherm offers New version (Model DTI-723 , DTI-966 , LPI-948) which are designed and developed using the latest micro-controller. The specification incorporated serves the every simple and critical process control applications of the industry. It accepts input from temperature sensors like thermocouple,RTD (Pt-100), Infrared thermocouple, or pyrometers generating mV or mA signals or from the level/flow/pressure/pH transmitters in the form of (4-20) mA. The input signals from thermocouples and RTD (Pt-100) are software Linearized for 1^oC/ 0.1^oC indicating accuracy. It can also be used for other process control applications like pressure control, level control etc. accepting input signals from the respective transmitter or transducers.

DTI-723/ DTI-966/ LPI-948 accepts universal input. User can select one of 8 differenttypes of input using back OR side panel DIP switch (model specific). This isthe added advantage over the fixed type of input.

Dual 4 digits displayallows simultaneous indications of the process value and the set value. Inaddition this model can give two nos. retransmission output of 4-20mAproportional to process value and/or set value with 12bit resolution, forremote indication of the process and/or set value.
