Saturation Pressure Apparatus
Advanced Technocracy Inc. is Manufacturer, Exporter & Supplier of Saturation Pressure Apparatus .
A bench top unit designed to introduce students to the characteristics of saturated water vapour.
The apparatus consists of a rectangular pipe loop incorporating a cylindrical boiler in one vertical limb. Pure water in the boiler is heated to its boiling point using a pair of cartridge heaters with variable power control. A sight glass on the front of the boiler allows the internal processes to be observed, namely boiling patterns at the surface of the water, and also allows the water level in the boiler to be monitored. Saturated steam leaving the top of the boiler passes around the pipe loop before condensing and returning to the base of the boiler for re-heating. The operating range of the boiler and loop is 0 to 7 bar gauge. The top limb of the pipe loop incorporates a PRT temperature sensor and an electronic pressure sensor to measure the properties of the saturated steam. A filling point on the top limb allows the loop to be filled with pure water and allows all air to be vented safely before sealing the loop for pressurised measurements. A vapour offtake, with isolating valve, allows steam from within the loop to be passed through a throttling calorimeter, the purpose of which is to demonstrate how the dryness fraction of the saturated steam in the loop can be determined. The steam expands to atmospheric pressure as it is throttled and a second PRT temperature sensor measures the temperature of the steam following expansion.
The apparatus is designed for safe operation with a pressure relief valve set to operate if the pressure rises above the working pressure and a Bourdon gauge that remains operational when power is disconnected from the electrical console
