Safety probes
Safety switches The water level in a steam generator must constantly be monitored to prevent it from falling below the minimum level established by the designer. In this case the generator could be seriously damaged, causing serious damage to people and property. It is for this reason that the control of the water level must be entrusted to safety devices compliant with the European PED Directive, certified by specific bodies.
In some cases it is also necessary to control the maximum water level. Safety probes, here are our solutions:
mmt 230 Minimum level limiter with SIL2/SIL3 self-diagnosis compliant with Directive 2014/68/EU (PED) – B+D certification;
mmt 231 Maximum level limiter with SIL2/SIL3 self-diagnosis compliant with Directive 2014/68/EU (PED) – B+D certification; 800 Safety probe (minimum or maximum level) compliant with Directive 2014/68/EU (PED) – B+D certification
The regulator models presented above, combined with the 800 probe, represent safety where there is water at pressure and temperature, especially in the field of boilers, and it is necessary to limit the maximum or minimum level of the ‘boiler water level"
