The SunSpot II igniter flame detector is a compact solid-state instrument designed to verify the presence of flame in igniters.
It achieves this by measuring the ionization of gases caused
by the combustion process. A probe resides in the flame envelope, and the
ionization is detected by passing a small electrical current through the flame
to ground.
The SunSpot II is reliable, requires virtually no maintenance, is very economical, and works for oil, gas and dual fuel igniters. The SunSpot II is designed for two applications:
- The replacement for the "Delta-P" flame detector used in corner-fired igniters. This configuration consists of the SunSpot II probe which fits into the existing high pressure tap pipe and the SunSpot II electronics module, which is mounted in a convenient location.
- Integral to an FPS igniter, a SunSpot II flame rod is installed in the igniter and the electronics module is mounted in a convenient location.
The electronic module has
three light emitting diodes (LED) that show the status of the detector: Power,
Ionization and Flame. The Flame light illuminates when flame is proven. Two
Form-C contacts are provided for system interlocking and flame indication.
Installation of the SunSpot II detection system as a retrofit is straightforward and can be done while the boiler is in service. The SunSpot II module may be mounted in the igniter cabinet in the area previously taken by the DP switch. The two Form-C contacts can be easily wired to duplicate the action of this switch.
