Armstrong furnace Ignition sensor

An ignition sensor is a device that senses the presence of flame in a furnace, and also controls the air supply to the burner.

The following article discusses the merits of Armstrong ignition sensors and their use case.

Armstrong offers a number of ignition sensors that are appropriate for various applications. The ASI-4000 is a sensor that is used to monitor the engine’s timing. When the engine is started, this sensor will detect the engine’s timing and then store it. The stored timing can be viewed on a diagnostic tool and will be used to calibrate the air/fuel mixture. The ASI-4000 is an integral part of the ignition process and needs to be monitored relative to changes in fuel quality, current, and voltage.

The ASI-2000 is a sensor that is used to monitor the engine’s


An Armstrong furnace has an ignition sensor to detect when “the pilot light is lit, gas pressure is sufficient, and the draft has been established and diverted.”

Ignition sensors are designed to work as a safety control that ensures that a furnace can light only after these conditions have been met.

Ignition sensors come in different varieties such as “thermocouple,” “coil,” and “optical.”

Armstrong furnaces offer many different types of ignition sensors for various types of furnaces.

This article examines the merits of Armstrong ignition sensor models in particular but does not cover the merits of other brands.

Armstrong furnaces are smart, high-efficiency products. They are designed with a special sensor that monitors the flame and automatically regulates the fire for optimum efficiency.
