PRODUCT DESCRIPTION:

Libratherm offers New version (Model HTC-948 and HTC-489) 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-948/ HTC-489 accepts universal input. User can select one of 8 different types of input using side panel DIP switch. This is the added advantage over the fixed type of input.

The controller HTC-948 and HTC-489 has 2 to 4 programmable set points. Each can be configured as either High Alarm or Low Alarm or Deviation Alarm or for Off state with programmable ON/OFF hysterisis through user friendly membrane key board. Dual 4 digits display allows simultaneous indications of the process value and the set value. In addition this model can give two nos. retransmission output of 4-20mA proportional to process value and/or set value with 12bit resolution, for remote indication of the process and/or set value.
