Fast thermocouple works

Fast thermocouple for measuring the temperature of molten steel, iron, and other high-temperature molten metal, is a consumption-type thermocouple. Its working principle is based on the thermoelectric effect metal thermocouple thermoelectric potential developed across the measured temperature of molten steel, iron and high-temperature molten metal.

Fast thermocouple features

1. high accuracy, good stability. There are computer processing control circuit zero and span calibration automatic cold junction temperature. Using precision reference voltage source, having long-term stability. Software technology to ensure accurate and reliable instrument. 

2. anti-interference ability 

3. the use of ultra-high brightness LED digital display. 

4. functional and easy to extend, can be equipped with printing interface. 

5. with segregated parallel BLD code output; or 4-20mA (1-5V) analog outputs. 

6. internal motherboard features indexing converts Jumper, each table can be equipped with two different thermocouple indexing number. 

7. both for fast temperature measurement can be used for continuous temperature measurement.

Fast thermocouple transport and storage

Fast thermocouple in handling with care during transport, must not get wet, the product should be stored at a relative humidity less than 80%, the air circulation, does not contain harmful gases causing corrosion product, FCL placed in dry warehouse.

Fast thermocouple structure

Rapid temperature thermocouple consists essentially even with the big head paper tube. There are positive and negative dual head dual wire welded to the wire compensation, compensation through wire embedded in the stent, the stent coat a small paper tube, thermocouple wire quartz support and protection. The outermost equipped with anti slag cap, all components of the concentrated load dump and refractory filler bonded into a whole, and not removable, it is for a single use .

Rapid temperature thermocouple use

1. according to the object and scope of the survey, select protective paper tube and apply different types of thermocouple temperature gun . 

2. the thermocouple temperature gun fitted over and seated, the secondary instrument pointer ( or digital display) back to zero, then the description of good contact, can be measured .

3. thermocouple temperature molten metal insert depth of about 100mm is appropriate, when measured not measured on the furnace wall or scum, do: fast, stable , accurate results obtained when the secondary instrument, should put the gun immediately, fast thermocouple temperature molten metal immersion time shall not be more than five seconds, or easily burn temperature gun .

4. temperature gun made from high-temperature molten metal after remove the used thermocouple, and install a new pause a few minutes, ready for the next measurement. Can not even measured even split, otherwise it will result in inaccurate measurements and fragile Thermometer .
