Thermocouple conductor is how to choose _ instrument between the field and the control room

Thermocouple, temperature controller, compensation wire, index number must strictly match. Such as K type thermocouple must match K type thermostat and compensating conductor. Otherwise the error of the measured is very large. Check the index number on temperature controller and thermocouple inside the lid has a mark. Platinum, rhodium - 10 Platinum thermocouple ( S) Indexing table ( 它的, 90). Platinum, rhodium - 13 Platinum thermocouple ( R type) Indexing table ( 它的, 90). Platinum, rhodium - 30 Platinum thermocouple ( B) Indexing table ( 它的, 90). Nickel, chromium - Nickel silicon thermocouple ( K type) Indexing table ( 它的, 90). , nickel chromium silicon - Nickel silicon thermocouple ( N) Indexing table ( 它的, 90). Nickel, chromium - Copper nickel ( Constantan) Thermocouple ( E) Indexing table ( 它的, 90). , iron - Copper nickel ( Constantan) Thermocouple ( J) Indexing table ( 它的, 90). , copper - Copper nickel ( Constantan) Thermocouple ( T) Indexing table ( 它的, 90). Thermocouple indexing table, platinum thermocouple Pt100 indexing table ( 它的, 90). Platinum thermocouple, Pt10 indexing table ( 它的, 90). Copper, thermocouple Cu50 indexing table ( 它的, 90). Copper, thermocouple Cu100 indexing table ( 它的, 90). Compensation wire, cable standard: the product technical indicators in line with the IEC584 - 3,GB4985 - 85 standard. Use refractory, heat-resistant temperature: FF - GS - 40 ℃ ~ + 250 ℃ refractory, high temperature resistant HF4B - GS - 40 ℃ ~ + 380 ℃ regular - 20 ℃ ~ + 100 ℃ type, name, specification of representation: the product is used index number is: S, R, B, E, J, K, T, and EA type thermocouples compensating lead wires. Compensating guide line, compensating electric cable match with hot thermocouple type compensation alloy wire insulation color 1. 2 x1 with K type thermocouple. 5 was compensation conductor ( Shielding) Example: ( 1) Refractory refractory said type KX - HF4BP - GS 2 x1。 5平方毫米( 2) Refractory according to type of heat-resistant EX - FF - GS 2 x2。 5平方毫米( 3) Ordinary type said KC - GV2P - GS 2 x1。 5 mm22, with E type thermocouple 4 to 2 x1. 5 was compensation cable ( Shielding) Example: ( 1) Refractory refractory said type KX - HF4BP - GS 4 x2x1。 5平方毫米( 2) Refractory according to type of heat-resistant EX - 基维辛迪- GS 4 x2x2。 5平方毫米( 3) Ordinary type said the EX - GV2P - GS 4 x2x1。 5 was the main technical data, compensation cable according to the varieties of products are divided into: 1 SC BC KC KX JX TX EA, the letter 'x' said expanded compensation conductor, the letter 'C' said compensation cable under the thermoelectric potential and resistance in accordance with the table below: 2, compensation cable moistureproof test the insulation resistance of not less than 24 hours in 40 ℃ water ( 10 meters) 25 mΩ。 3, compensation cable heat aging five times the outer diameter experiment was carried out after 24 hours, the 5000 v / 1 min not breakdown voltage test. Need to indicate the type and specification when you order it, line core section, some shielding ways, and number of cases: the EX - GV2R - GS 2×2。 5mm21500m EX- 基维辛迪- GS 24×2×2。 5mm21000m( Total shielding) KX - HF4BPP- GS 12×2×1。 5mm212000m( Points on the screen)
