The rupture indicator that can survive the disc's breakage

In all those cases where an industrial plant processes corrosive or aggressive substances, it is often impossible to install a traditional rupture indicator. For this reason, magnetic sensors have been introduced. They couple a disc-mounted actuator with a sensor installed outside of the piping itself, and thus protected from the subestances running through the pipes and from the the consequences of the disc's rupture under excessive pressure.

DonadonSDD's magnetic rupture indicators combine the reliable performance and advantages of magnetic technology with an ATEX certification which allows for their installation even in those plants which present explosion risks and are thus regulated by such stringent standards.

NAM03HT

Donadon magnetic NAM 03/HT rupture indicators are recommended for use with our rupture discs.

The NAM 03/HT indicator is composed of:

a magnetic proximity type sensor installed in the corresponding threaded housing downstream in the rupture disc holder to detect opening

a target with a permanent magnet supplied with the disc

When the disc opens the magnet is displaced and the sensor activates. Replacement discs are supplied with a new target.

NAM 03/HT is an intrinsic safety device certified

ATEX II 2GD Ex mb II T4/T6

Ex tD A21 IP67 T135°C/T85°C

ATEX II 1GD Ex ia IIB T3/T6

Ex iaD 20 T200°C/T85°C

It can therefore may be used in locations where potentially explosive atmospheres are continually present (classified zones 0, 20 and 1, 21 and 2, 22 according to European Directive 94/9/EC (ATEX)).

NAM 03/HT is normally supplied with 2 metres of bipolar cable. The cables of the alarm system must be connected to the plant’s safety system through an adequate safety barrier.

Ex ia barrier -> zone 0; 20; 1; 21; 2; 22

Ex ib barrier -> zone 1; 21; 2; 22
