MEMBRANE SIGNAL TRANSMITTER
We developed the membrane signal transmitter for bursting discs (rupture disks) especially to meet the particular requirements of the chemical and pharmaceutical industry. It consists of a high-quality PEEK (polyether ether ketone) film equipped with a silver strip conductor. This material combination makes it particularly resistant to high temperatures. The strip conductor is wired, with the length of the wire variable according to customer requirements. This means that the membrane signal transmitter can be used in a temperature range between -30°C and +200°C. In combination with an approved isolating switch amplifier, it can also be used in explosion-protected areas.
Berstscheiben Schlesinger provides membrane signal transmitters in two versions: in strip form and in disc form. The disc is placed over the entire bursting disc (rupture disk), while the strip is clamped across the bursting disc (rupture disk). This allows for safe transmission of signals from bursting discs (rupture disks) with a large nominal width. In the event of a fault, a bursting disc (rupture disk) equipped with this signal transmitter will tear open together with the membrane film. The closed circuit previously formed by the live silver strip conductor is interrupted and the fault is immediately transmitted to the internal process control system.
Depending on your application, we can manufacture the membrane signal transmitter in sizes DN25 to DN500, either in combination with a suitable bursting disc (rupture disk) or as an individual product. In the latter case, the membrane signal transmitter may be used upstream or downstream from a safety valve. The low installation height amounting to 5 mm allows for bursting discs (rupture disks) already installed in a plant or tank to be retrofitted.
