Yamari Products

Thermocouples Precious metal and base metal thermocouples widely used in industries for the measurement of temperature in the range from low to ultrahigh temperatures. With the best staff and advanced technologies, we manufacture a wide variety of quality products for use in general industry and explosive and hazardous areas. Resistance Temperature Detectors (RTDs) Platinum resistance

thermometers utilizing the phenomenon that the electrical resistance of any metallic conductor varies according to its temperature are widely used in industries for the measurement of temperature in the range from cryogenic to high temperature.

With the best staff and advanced technologies, we manufacture a wide variety of quality products for use in general industry and explosive and hazardous areas Tungsten Rhenium Thermocouple The demand for measuring very high temperature in research laboratories, specialized furnaces, and in other high temperature experimental and industrial applications has grown dramatically in recent years.

In response to this demand, Yamari Industries has been providing its Tungsten Rhenium thermocouples and expert knowledge to customers needing accurate measurements of high temperatures in a wide range of fields.

Now, Yamari is pleased to announce it has developed a new type of Tungsten Rhenium thermocouple, “VAC-Curate 2100”, in conjunction with a world class Japanese manufacturer of quality alloys and can supply thermocouple elements conforming to ASTM standard E988-96 in matched pairs

THERMOCOUPLE

METAL SHEATHED THERMOCOUPLE (THERMIC)

Metal Sheathed thermocouple is comprised of metal sheath in which the thermoelectric elements are embedded in highly compacted magnesium oxide (MgO) insulation.

The construction guarantees a superb insulation quality and high resistance to pressure, and has, in addition, an excellent flexibility, which has been given to it by annealing in a proper method
