适用范围：This European Standard specifies requirements for limiters (or limiting devices) which are incorporated intosafety systems for water-tube boilers as defined in EN 12952-1.A limiter (or limiting device) can be either:a safety accessory as defined in the Pressure Equipment Directive, Article 1, clause 2.1.3, and needs toinclude the safety logic and final actuator, orone element of a safety system, for example, a self-monitoring water level sensor used as part of a safetyaccessory as defined in the Pressure Equipment Directive, Article 1, clause 2.1.3. The overall boiler protectionfunction shall be provided in association with additional safety logic (where appropriate) and a finalactuator.The design requirements and examination of functional capability for the limiters are covered in this EuropeanStandard.For an explanation of the extent of the limiter (or limiting device) see Figure A.1.
