Sensors and switches

552 parts · 33 brands

Sensors and switches are the measuring and control elements that keep a burner or boiler running safely and efficiently. Flame sensors confirm ignition and hold the burner in operation; thermocouples and thermopiles generate the small voltages that power gas valve safety circuits; NTC sensors feed water and flue temperatures to the controller; pressure switches monitor air, gas and water pressure; thermostats set and guard operating limits. These components sit throughout the appliance — in the combustion head, the heat exchanger, the water circuit and the flue path.

Choosing the right part means matching the parameters the manufacturer specifies: sensing element type, temperature range or switching point, working pressure, electrical connection and cable length, thread size or flange form, and any approval marking required for the application. Most components here carry a maker's part number — from ACV, Baltur, Beretta, Bosch, Brahma, Ceme, De Dietrich, Dungs, Fema or Honeywell — and a cross-reference from another brand's order number will find the equivalent in this catalogue.
