BS&B Safety Systems H1-0-0083-337 Burst Alert Sensors

The BS&B Safety Systems Burst Alert Sensor SAS 3” (Catalog 77-1010; part H1-0-0083-337) provides immediate electrical notification when a rupture disk relieves pressure, signaling a disk-event to a control system or a BS&B Burst Disk Monitor (BDM). This sanitary-alert variant (SAS) is designed for downstream installation of sanitary disk assemblies and is compatible with BS&B monitoring equipment or other suitable electrical inputs. The sensor is a normally closed device that uses a polymer membrane and a tantalum conductor ribbon; when a pressure-relief event occurs, the flowing medium stresses the membrane and causes the conductor to fracture, switching the circuit to an open condition and delivering a clear alert signal. Electrical specifications designate operation in a closed control circuit with a maximum recommended current of 500 mA and a maximum voltage of 24 VDC, enabling reliable signaling without excessive power. The unit features robust internal pin connections with a threaded housing and a 3-pin arrangement (positive, negative, shield) for secure wiring. Seals typically use pressed-fiber gasket material, with optional alternatives such as Teflon with glass fiber or Garlock 3000 available on request. In practical use, SAS sensors are installed downstream of the rupture-disk device to provide prompt notification of disk activation, supporting rapid maintenance actions, minimizing downtime, and reducing product loss.
