SPECIFICATION

Introduction: The equipment consists of a heated water bath together with a set of instrumented shaped test pieces. Each of the shapes incorporates a thermocouple to measure the temperature at the center of the shape. A total of six shaped test pieces are provided, i.e. three simple shapes (a rectangular slab, a long solid cylinder and a solid sphere) each manufactured in two different materials (brass and stainless steel). Measurements taken on a shape in one material can be used to confirm the conductivity of a similar shape constructed from a different material. Transient-temperature/heat-flow charts are supplied for each of the shapes.

 


Specifications: The water is heated by an electric heating element in the base of the bath having a nominal rating of 3.0 Kw.An adjustable thermostat, at the base of the water heater allows the water to be heated to a predetermined temperature before taking measurements.Thermocouple at the base of the flow duct, inside the water bath, allows the temperature of the water to be monitored and adjusted to the required temperature. Comprises of a set of seven solid shapes, manufactured in three simple shapes and two materials. Each sample has a permanently installed K-type thermocouple inside.The thermocouple mounted on the shape holder contacts the hot water at the same instant as the solid shape and provides an accurate datum for temperature/time measurements.The resolution of all temperature readings is 0.7°C.A circulating pump mounted alongside the water bath draws water from the bath and returns it to the base of the vertical cylindrical flow duct.A comprehensive instruction manual is included.
