Description Générale

The Computer Controlled Saturation Pressure Unit, "TSPC", consists of a water boiler, including a computer controlled immersion heating element, and a sight glass to observe the boiling patterns in the water surface and control the water level in the boiler.

The saturated steam formed in the boiler passes through a throttle valve and is expanded to atmospheric pressure in a throttling calorimeter with the purpose of determining the dryness fraction of the saturated steam.

The temperature and pressure are measured after the boiler to determine the properties of the saturated steam, and after the expansion in the throttling calorimeter. In addition, a force sensor measures the weight of the condensed water.

The unit includes all the safety measures required for a safe operation, such as relief valve and pressure switch to limit the working pressure, and transparent protection panels.

This Computer Controlled Unit is supplied with the EDIBON Computer Control System (SCADA), and includes: The unit itself + a Control Interface Box + a Data Acquisition Board + Computer Control, Data Acquisition and Data Management Software Packages, for controlling the process and all parameters involved in the process.
