    Mass m [g] 80-120 depending on design

    CE - conformity EC Directive 89/336/EWG

    IP system of protection The IP system of protection as specified in the data sheets generally applies, with their

    mating plug connected. Relative pressure transmitters usually require a ventilated mating

    plug and/or cable to aloow for pressure compensation. From a pressure range of 60bar,others upon request a ventilated mating plug and/or cable is not necessarily required.
