Boiler & Burner Sensors
ETC offers a range of dedicated self-checking pressure and temperature sensors for boilers and burners that can be used as part of an ETC6000 Burner Management System.
The ETC6043 CANbus Sensor is installed between the two gas isolating valves on the gas train. Once installed the sensor can be used as part of the gas valve proving system and can provide high and low level alarm and interlock functions. Because the sensor is self-checking, the need for mechanical pressure switches is eliminated.
The ETC1030/1034 & ETC1040/1044 are self-checking steam pressure and temperature sensors. These provide the measured value of the heating medium within the boiler so that control can be achieved locally using internal PID functions to vary the firing rate of the boiler and position the rotary actuator drives throughout the chosen profile. If an ETC self-checking pressure sensor is used to provide the boiler high-limit lockout then a pressure switch is not required.
The ETC6083 CANbus Combustion Air Pressure Sensor replaces air pressure switches that are used to confirm that the fan is running to provide air for combustion. These switches have to be set at the lowest possible output of the fan, typically ignition or low-fire. Replacing this with a pressure sensor allows characterisation of the combustion air pressure across the profile, we can then monitor this and in the event that a air pressure fault is detected anywhere on the profile curve lockout the burner bringing enhanced safety benefits.
Other functions such as alarm thresholds and warming limits can also be assigned by adjusting parameters within the main ETC6000 Burner Management System series.
