DETEC-SAF? Alarm System

DETEC-SAF? ALARM SYSTEM immediately warns of a ruptured disk or                      exploded vent.

The                      DETEC-SAF? ALARM SYSTEM combines the Magnetic Burst Sensor (MBS) and the                      Burst Disk Monitor to provide continuous monitoring of rupture disk (bursting disc) or                      explosion vent integrity.

MBS                      Sensor

The MBS                      is a magnetically activated sensor, spot-welded to the vent or                      disk.

Electrical                      Specifications

• The                        MBS meets the requirements of the IEC 144 IP67, which ensures complete                        protection against ingress dust and water.

• The                        MBS unit is supplied with three feet of twin core PVC insulated and                        sheathed cable. It also is available with flexible 302 stainless steel                        armored lead. Armored length is three feet.

Maximum                      Ratings:

24V DC                      -- 300 mA
                     110V AC -- 60 mA
                     Maximum Peak Voltage                      Permissible:

200V AC                      for non-hazardous / non-critical conditions only.
                     Suitable for                      intrinsically safe power levels - max 5V -- 20 mA

Installation

The                      entire MBS sensor is factory installed. The sensor is also available for                      retro-fitting in the field. MBS for domed VENT-SAF PLUS? and for EXP/DV                      requires frame side installation in field.

Features

• The                        MBS sensor consists of two components attached to carrier plates and                        spot-welded to opposing segments of the flat vent or disk.

• Plastic encapsulation of the sensor components ensures complete                        protection from environmental conditions.

Benefits

• Burst                        performance or service life or rupture disks (bursting discs) and explosion vents is                        unaffected.

• Uses                        most standard catalog burst pressures and materials for disks and                        vents.

• Performs over a wide range of operating temperatures.

• Resists corrosion from chemicals, dusts and weather.
