S/B/R type Receptacle matching with S/B/R 604 disposable expendable thermocouple tips

S/B/R type Receptacle matching with S/B/R 604 disposable expendable thermocouple tips

Product Description

The wires used in the thermocouple contact blocks are extension wires. They are separated into type SC(RC), type BC and type WRe3/25(D).They are separately matched with Pt10Rh-Pt (Pt13Rh-Pt) Pt30Rh-Pt6Rh and WRe3-WRe25 expendable thermocouple.

Thermocouple contact blocks are mainly used for rapid temperature measurement in metallurgy and foundry industry. Loop is formed, temperature signal is transmitted after connecting contact blocks  with thermocouple, thermocouple lance, extension wire, and secondary instrument.

The corresponding model of extension wire is applied. The high-tech welding technique is adopted to lead to the wire. The soldering and the third component are excluded in an attempt to improve the precision of temperature measurement. The insulating part employs high polymer material which is heat resistant(200℃), the integration of injection molding is used. Besides, the positional accuracy is high.

I Purpose and Working Principle of Disposable Thermocouple:

Used for measuring the temperature of molten steel and high-temperature molten metal, disposable thermocouple is disposable. Based on the thermoelectric effect of metals, it works according to the temperature difference between its two sides.

Ⅱ Product Specifications and Performance Comparisons:

Ⅲ Structure

Disposable thermocouple is mainly composed of temperature measuring probe and a big paper tube. Positive wire and negative wire of the temperature measuring probe are welded to a compensating lead wire embedded in a support bracket covered by a small paper tube. The thermo wires are supported and protected by quartz. The temperature measuring probe is covered by a cap to protect from dregs. All the components are put into a thermocouple tip and are bonded by fire-resistant filler into a whole. Therefore, the fast thermocouple is for one-time use.

Ⅳ Usage

1, To select the appropriate length of protective paper tube and temperature measuring gun according to the object and scope of the measurement

2, Attach the disposable thermocouple to the temperature measuring gun, make the pointer of the secondary instrument (or digital display) back to zero. Begin to measure.

3, It is recommended to insert the disposable thermocouple in to the molten steel at the depth of 300-400mm. Do not touch the furnace wall or scum. Bring up the temperature measuring gun immediately after the secondary instrument get results. The soak time of disposable thermocouple in molten steel should less than 5 seconds, otherwise the gun may be burned out.

4, Change the used thermocouple into a new one, and pause for a few minutes to get ready for the next measurement.

Ⅴ Transport and Storage

Be careful when assembling and removing the parts. Keep dry in the transportational process. The products should be put into cases and stored at warehouses where the relative humidity is less than 80%. Keep the air flowing. The air should not contain harmful gases which may corrode the products.
