L.D. BHATTAR & CO SOURCE TO ALL CABLE REQUIREMENTS Home About Us Products Enquiry Contact Us     As the generated voltage in the thermocouple circuit depends upon the difference of temperature between the hot and cold junction of the thermocouple, the accuracy of the measured temperature of junction depends on keeping the other junction at a known constant temperature. The temperature in the connection cap isn’t constant. For this reason the legs of the thermocouple are extended by means of COMPENSATING CABLE LEADS made of material which will not produce, in junction with the thermocouple metal, any additional voltage. Thus the COMPENSATING CABLE LEADS effectively extends the junctions of the thermocouple to a convenient point of constant temperature ensuring the accuracy of the measured temperature for which the thermocouple is used.

It has outstanding electrical, thermal and chemical properties.The operating temperature of PTFE is from - 65°C to 200°C for silver plated and - 65°C to 60°C for Nickel plated wires. Type ET (250V AC RMS), Type E (600V AC, RMS)and Type EE (1000V AC RMS) are manufactured strictly as per the specification of JSS 51004.ADVANTAGES: 1. Excellent thermal stability - suitable for use for- 65"C to 260"C. (2) Suitable for very wide frequency range (D.C. to above 10,000MHz) over wide temperature range. (3) Fire (flame) proof. (4) Inert to practically all chemicals even at elevated temperatures. (5) Smaller size, lighter weight and much higher reliability. (6) Lowest dielectric constant (2.1) dissipation factor (below .003) and highest volume and surface resistivities (in Teraohms). (7) Flex life - Excellent. (8) Non-contaminating. Non-toxic and bio-compatible. (9) Corona Resistance-Fair. (10) Cold-flow and cut through resistance - Fair, (good mechanical strength). (11) Resistance to ultra violet radiation and stress cracking-Excellent. (12) Soldering iron resistant and suitable for high density wiring. (13) Resistant to fungus and mould growth.APPLICATIONS: (1) Computers. (2) Refrigeration equipment. (3) Electronic test equipment (mobile and man pack wireless sets). (5) Electronic equipment for aircraft, Radar, navigation (6) Flight simulators. (7) Electronic control equipment for atomic energy satellite launching, ground control, reactor and process control, telephone exchange, lifts. (8) High performance motors, transformers and rectifiers (9) Temperature control valves; Furnace and oven wiring. (10) Load Cells and pressure transducers. (11) lnfra Red sensing equipments. (12) Air field lighting equipment. (13) Thermocouple and heat sensing leads. (14) Control panel wiring.

BHATTAR & CO SOURCE TO ALL CABLE REQUIREMENTS Home About Us Products Enquiry Contact Us   Products|Compansating Cables COMPENSATING CABLESCONSTRUCTION: Compensating cable is having 2 cores of different metal wires, having characteristics similar to that of thermocouple with which it is intended to be used. *each core is electrically and thermally insulated individually. * Both core are further insulated or sheathed as per user’s specification.* each core of the cable of one or more wire as per user’s specification.INSULATION: The compensating cable cores are insulated with (a) Flame-proof compounded High Temperature Cable fabric braiding over heat and moisture resistant double fibre glass covering, or (b) Polyvinyl-chloride (PVC) coating, or (c) Heat resistant coated double fibre glass covering, or (d)Any other type of suitable insulation as per use’s specification e.g., etc. generally conforming to IS8784.SHEATHING: (a) Flame-proof compounded High Temperature Cable Fabric braiding, or (b) Poly-vinyl-chloride (PVC) or /PTFE (c) Fibre glass with or without heat or moisture resistant coating or (d) Any other type as per user's specification.SHIELDING: Plain or Tinned Braided copper wire shielding is provided. Alternatively it may be heat resistant aluminized polyester foil called mylar tape in parallel connection of one drain wire of tinned copper.ARMOURING: The pattern selected depends upon whether protection is required against moisture (attracted by High Temperature Cable fibres), mechanical damage or both. A further decisive factor is how the Cables are run, fixed, trailing and in the former case whether surface run or laid in conduit. * Armouring is generally provided of galvanised steel wire. But any other suitable wire may be used as per user’s specification.COLOUR MARK: The insulating sheaths have different colours to indicate the type of compensating leads. The positive pole is always coloured RED as per lS & WHITE as per B.S. negative BLUE Except in case of Fe/Const where positive is YELLOW. Any other colour code as per user's specification can be provided.PACKING: Normal packing will be in running length of 100 Metres but could be made in running length up to one kilometre.
