SURGE Series: Lightning and Transient Protectors

The best geotechnical monitoring system is useless without the ability to reliably move data between instruments. Despite the increasing place of wireless technology in data transmission, RST Instruments’ signal cables are often the best or only way to ensure that the data your company depend on are always at your fingertips. RST offers a full range of outdoor rated signal cables to connect our vibrating-wire piezometers, load and pressure cells, crack meters, joint meters, and other instruments.

RST’s signal cables have between 2 and 26 conductors to match any data-transmission needs, with jackets of varying thicknesses and materials to strike the right balance between unobtrusive size and durability. Abrasion-resistant and anti-stretch jackets, with or without Kevlar reinforcement, are available for signal cables exposed to impacts or tensile stresses. Other options include water-blocked and grease-blocked jackets, HDPE jackets for acidic environments such as landfills and saltwater, and vented cables for barometric compensation. And all RST signal cables are metre marked for ease of installation and repair.

In addition, RST’s SURGE Series transient protectors keep your system safe by grounding transient electrical fields that can damage sensors and terminals connected by long horizontal wiring. During a transient, the device’s four signal lines and up to two shield lines are clamped to ground. Once the transient is over, the device self-resets, allowing normal operation to resume. SURGE Series transient protectors can be installed in either a NEMA-4X enclosure or in a compact T35 DIN-rail housing with screw-terminal input/output and ground connection through a DIN rail.
