Analogue indicator Type SIR3 (round) and Type SIQ3 (square) with moving-coil element NOR/S Construction type Scope of application Type SIR3, SIQ3 analogue indicators are commonly used in the fields of the shipbuilding industry, transport technology, machinery and equipment. They are suitable for use in harsh ambient conditions and comply with the requirements of DIN EN 50155 for railway applications and the ship classification society DNV-GL. Thanks to its mechanical design, the casing is extremely resistant to salt spray, enabling use in outdoor applications. The DIN-standardised casing sizes are suitable for installation in control cabinets and control panels with prestamped standardised installation openings. Display principle The display on the SIR3, SIQ3 is based on a 1 mA moving-coil element. The moving-coil element contains a coil that rotates in the magnetic field of a permanent magnet. When a direct current flows through the coil, a second magnetic field is produced in the opposite direction of the magnetic field of the permanent magnet. The two magnetic fields repel, thus rotating the coil with an attached pointer. A coil spring acts against the magnetic force in the coil. Special features • Robust glass-fibre-reinforced plastic housing, also suitable for outdoor areas; round or square design • Individual scale design and corporate logos possible • Also available with a centred zero moving-coil element (±1 mA) • Direct connection of the current, voltage measuring signals • Complies with DNV GL certification (other certifications available on request) Datasheet DB-SIR3/SIQ3-EN | V01.05 | 25/02/2019 | Valid from product revision Rev.A | www.noris-group.com | [email protected]
