Máy Đo Nhiệt Độ- General Instruments India - General Instruments Vietnam- Ans Vn

A state-of-the-art manufacting facility, continuous research & development, innovative technology and stringent quality improvement at every stage have been some of the key factors in the manufacturing process. Over the last forty three years since inception.

General Instruments Consortium has buit a first class reputation of total understanding of customer requirements and needs, thus delivering excellent product and services at competitive prices.

At the General the ethics, commitment and integrity are valued the most, which reflects in the philosophy of achieving total customer satisfaction.

With a presence in major cities in India and a growing internation networkacross all continents,General is in a position to reach all over the world.

The conventional thermocouple is used with an outer protecting tube or thermowell to protect it from aggressive and corrosive process condition. This improves longevity of the thermocouple. However, response time is poor. To overcome above problem, has designed MI Thickwall Thermocouple having thicker wall with relatively larger conductor diameters. This construction enable the user to insert the thermocouple directly in the process without a protecting tube or thermowell, improving response time considerably.

General indegenised the Skin Thermocouple assemblies first time in India. Tube Skin Thermocouples manufactured by us are reliable for measurement and control of tube surface temperature in fire heaters. Accurate temperature measurement is important for prolonging heater tube life, for ensuring safe and efficient operation. We have been supplying tube skin thermocouple assemblies in quantities to majority of the projects in India as well as exporting to various countries.

The basic thermocouple is normally of 12.7 mm OD with relatively higher sheath wall thickness, mineral insulated (compacted MgO) and in variety of sheath materials such as SS310, SS446, Inconel® 600, Incoloy® 800 etc. The Junction is generally grounded. However ungrounded junction also is offered, as customer requires. Mineral Insulated (MI) thermocouple is manufactured by Cold drawing and annealing (heat treatment) process in controlled atmosphere. The heat treatment (which is controlled within +/- 20C) is carried out in hydrogen atmosphere to avoid surface defects & partial oxidation of conductor.

Where space limitations and cost consideration are of prime importance, multi-point thermocouple assemblies come into picture which are used for measuring and controlling temperature in a reactor having different temperature zones. Any thermocouple assembly with measuring junctions located at more than a one-immersion depth is commonly referred to as a multi-point. As the number of variations possible in multi-point assemblies is virtually limitless they are generally designed and manufactured to meet the requirements of individual applications. As different multi-point designs vary tremendously, careful consideration should be given to such variables as the positive location of measuring junctions and the ease/cost of replacement. 

General with its vast experience has designed and developed several types of multipoint assemblies, which are performing satisfactorily at hundreds of installations in several parts of world. Some designs allow for replacement of individual elements while others require replacement of the entire assembly. In either case, complete shut down of the process line may not be required depending upon important design considerations. Testing of multipoint is another specialised area. Our manufacturing set-up is equipped with all latest testing equipments to perform all stringent tests.

 

 

General has the capability of supplying temperature Element (T/c as well as RTD) assemblies suitable for temperature transmitters. The transmitter either can be mounted in the enclosure (Head) or connected to the extension (in the form of Nipple-union-nipple) that comes with built in enclosure. (with or without indication) The assemblies are offered complete with element, head & thermowell. In either case, the spring loading is provided ensures proper contact of the element to the bottom of thermowell. Moreover the assembly (if the transmitter is in our scope) will be duly calibrated.

The assemblies are generally suitable for various models of reputed make. We have been supplying these to major transmitter manufacturers across the globe.
