Temperature monitors and temperature limiters are tested according to Pressure Equipment Directive 97/23 EC, meet the requirements of DIN EN14597 and can thus be used for heating systems according to DIN EN12828, for steam and hot water systems and for district heating systems. The devices with safety function (STW, STB) are self monitoring, i.e. in the event of breakage or leaks in the measuring system the circuit is opened and the system is switched off towards the safe side.
