Saturation Pressure

Specification:

• A bench top unit comprising a boiler vessel and pipe loop with a pressure relief valve to limit the operating pressure to 8 bar gauge. A sight glass on the front of the boiler allows the boiling patterns to be observed and a Bourdon type gauge indicates the pressure in the apparatus at all times for safe operation.
• A throttling calorimeter mounted adjacent to the pipe loop allows the condition of the saturated steam to be determined by measuring the temperature of the steam following throttling to atmospheric pressure. Temperatures in the pipe loop and inside the throttling calorimeter are measured using PRT sensors and pressure in the loop is measured using an electronic pressure sensor.
• An electrical console houses the necessary electronics with current protection devices and an RCD for operator protection. A digital meter with selector switch displays all sensor measurements. Corresponding signals are routed to an I/O port for connection to a PC. An optional interface device and educational software package is available.
• The boiler is heated by a pair of 500 W electric heating elements with variable power control and over-temperature protection.
• A comprehensive instruction manual is included with a range of fully detailed Laboratory Teaching Exercises.

Key Features:

• Measurement of the relationship between temperature and pressure of the saturated vapour in the loop
• Convenient control of heat input to the boiler using variable power control
• Sight glass in the boiler allows observation of the boiling patterns in the water
• Safe operation with pressure relief valve and permanent indication of system pressure
• Pressure and temperatures measured can be logged using a PC (optional teaching software available)
