适用范围：This European Standard specifies requirements for limiters (or limiting devices) which are incorporated intosafety systems for shell boilers as defined in EN 12953-1.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 boilerprotection function needs to be provided in association with additional safety logic (where appropriate)and a final actuator.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.
