PRODUCT DESCRIPTION:

Libratherm offers New version (Model HTC-723 and HTC-966) 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^oCindicating 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.

HTC-723/ HTC-966 accepts universal input. User can select one of 8 different types ofinput using back panel DIP switch. This is the added advantage over the fixedtype of input.

The controller HTC-723 andHTC-966 has respectively 2 to 4 and 2 to 6 programmable set points. Each can beconfigured as either High Alarm or Low Alarm or Deviation Alarm or for Offstate with programmable ON/OFF hysterisis through user friendly membrane keyboard. Dual 4 digits display allows simultaneous indications of the processvalue and the set value. In addition this model can give two nos. retransmissionoutput of 4-20mA proportional to process value and/or set value with 12bitresolution, for remote indication of the process and/or set value.
