Libratherm has contributed its 25 years of experience by designing these versatile series of microcontroller based TemperatureProcess Indicators and controllers for general purpose Industrial usage. These are developed and manufactured to suit varied industrial temperature and process indication and control applications where precise indicating and controlling accuracy. The Indicator series DPI-912 and DPI-902 offers Universal or fixed input of J, K or any other thermocouple, RTD(Pt-100) and 4-20mA linear signal. For temperature measurement 1oC0.1oC Indicating accuracy is guaranteed using software linearization algorithm and with linearized retransmission output. Please see details specification sheet as given below.

Libratherm offers Microprocessor based Eight Zone PID Temperature Controller (Model PID-8000) (AS GOOD AS EIGHT PID CONTROLLERS IN A SINGLE UNIT) for processes requiring multiple zone heating or heating plus cooling control. It is most suitable for difficult processes which results in frequent system disturbances, and applications where accurate and simultaneous temperature control of number of heatingcooling zone is required. It also eliminates the need for number of individual PID or ONOFF Temperature Controllers thereby saves on cost and panel space. It can accept 8 Thermocouples or RTD (Pt-100) Inputs and can provide switching PID or ONOFF Control output in the form of DC Pulses or SSR Drivers for heating and cooling. It can also simultaneously provide 8 analog PID control Outputs in the form of (4-20mA) or (0-5) volt, which can be used to drive external SCR Heater Power Controller or other actuators. Open or Faulty sensor indications for each zone is also displayed with the respective Zone No. Each zone loop parameters like PID, SET, Hysterisis , Power Limit and Ramp Time values can be programmed from the user-friendly front panel membrane keyboard. The display scan rate is programmable from 1 to 99 seconds, whereas the internal control scanning is at the rate of 100mS. It also provides common High and Low alarm relay outputs which can be used for external temperature dependent inter locking or audiovisual alarm.PID-8000 is available in standard 12 DIN (192 x 96 x 200mm) for 8 zones, 6 zones or 4 zones. It operates on 230 VAC with built in high and low supply voltage trip circuits. It is also protected against industrial RFIEMI Interference. Libratherm also supplies complete Multizone Temperature Control Panel, which finds its applications in Plastic Extruders, Plastic Injection, Tunnel Furnaces, Ovens etc.ApplicationPlastic extrudersHeat treatmentRubber industryFurnace Oven controlFood processingEnvironmental chambersMulti zone furnaceMetal industryCold Storage and Chilling plantsLaboratory equipment etc.

Specifications Accurate control of Torch to work distance be it Cutting of Welding, plays very important role for the quality of the end result Torch Height Controller (THC) is also known as Arc Voltage Controller (AVC) it is the device which maintains the arc gap between the torch & the work piece. Stepper motor driven vertical slide with motor driver & the controller allows the torch to move up or down depending upon the parameters set. Arc voltage which acts as a Feedback to the controller as reference voltage, allows operator to set the Torch to Job gap as per the process & the quality requirement. Arcraft Plasma has introduced Digital model DigiTHC100 Features of the DigiTHC100 are.......... Suitable for welding processes like TIG, Plasma welding, PTA or Powder plasma welding. Suitable for Plasma Arc cutting. Wide range of Arc voltage acceptability. Well protected from the High Frequency interference. Piercing program for plasma cutting. Programmability in terms of Arc Voltage or Arc Gap distance. Independently adaptable to any Plasma cutting or Welding power source Independently adaptable to CNC profile cutting machine. Independently adaptable to Welding Automation. Initial Height Sensing (IHS) comes in handy to pre-adjust the required gap before start of process. Advantages of DigiTHC100 Plasma Cutting Improvement in cut quality Improvement in consumable life upto 20% High productivity at high dimensional accuracy of cut components. Elimination of near collision condition of Torch & job. Welding Uniformity of weld beads Controlled weld heat input eliminates chances of higher percentage of dilution, lack of penetration, undercut etc. Easy adjustment of weld pool fluidity depending upon the application of weld & welding process by maintaining the constant gap & hence the heat input. Dramatic improvement in weld aesthetics.
