1.4. THE 501TS – TOTAL REDUCED SULFUR CONVERTER
The 501TS oxidizes reduced sulfur compounds to SO
2
in a high temperature quartz oven.
1.4.1. Heater Characteristics and Control
A front-panel-mounted, programmable digital temperature controller regulates power to the heater.
•
Power to the heater is switched by a solid state, zero-crossing relay.
•
An over/under-temperature alarm contact closure is located on the rear panel.
•
The alarm set point has been preset in the temperature controller.
•
The heater temperature is sensed by a Type S (distinguished from other thermocouple types by its
wire colors, red and black) (Platinum-Rhodium) thermocouple probe inserted in the bore alongside
the quartz tube.
CAUTION!
Do not use any other type thermocouple, as the controller settings have
been preset for Type S.
The quartz tube carrying the sample mixture runs through the core of the heater and is heated by radiation
from electrical heating elements at the heater bore surface. See Figure 1-4 for a layout view of the
converter.
WARNING!
Ensure proper line voltage is selected prior to plugging unit into the
power source.
CAUTION!
Do not touch – the quartz tube and heater are very hot.
