Industrial research offers ionisation flame detector. These burner sequence controller uses single electrode for ionisation in addition to flame sensing in place of two separate electrodes. Single electrode enables for compact design of pilot burner system. Ira burner sequence controller is intended to work as a direct replacement for kromschroder make flame detector and sequence controller. The terminal connections can be configured to that of kromschroder, if required. This instrument is usable with ltv flame sensor or with two separate electrodes, one for ignition and the other for flame sensing.
