Summary
This is an epoch-making air/gas ratio regulating equipment containing a micro-computer developed for burners used in industrial fields. Air temperature, air flow and gas flow are displayed at the front panel and also error message is displayed. This can be installed easily in existing furnaces and has the advantage of saving energy for industrial furnaces using city gas or other fuels.

※Differential pressure transmitter P-3000 is a converter with a function of automatic zero-point adjustment for use in pressure measurement to convert air pressure to electric current. Depending on the ambient temperature, the zero point (output at pressure zero) may be deviated. However, owing to this automatic zero-point adjustment function, P-3000 requires no maintenance. Upon turning on the power supply, the automatic zero-point adjustment is performed 1 times in 20 minutes. Simplified types without this automatic zero-point adjustment function are also available as PU30.
Flow sheet
This is to regulate the combustion air flow through output signal from temperature controller of a furnace. Air flow is sensed as a delta pressure of a air flow meter installed in air lines and the signal of it is put into the micro computer of a Sectron. Calculating the input simultaneously, the Sectron moves fuel regulating valve and regulate fuel flow in proportion to air flow, in order to fire at fuel air ration set in advance.
