Signal Indication

Product catalog summary

Overview: The document discusses analog indicators used for high precision display of process parameters, focusing on their construction, measuring systems, and specifications. These indicators are primarily used for trend monitoring and direct reading of process parameters.

Construction and Measuring Systems: Analog indicators are available in circular scales, direct-reading instruments, or bar graph displays. They use motor-driven potentiometers designed as bridge or balancing circuits, accepting resistance, current, or voltage inputs. These systems can exceed 360° shaft rotation, useful for applications like wind direction or variable-pitch propeller position indication. Rotary magnet systems with a threefold tapped potentiometer allow for signal indication beyond 360°.

Design and Models: Indicators come in various casings (circular, square, rectangular) for wall or flush mounting, with sizes ranging from 48 mm x 48 mm to 1 m x 1 m. They can feature single or multicolored scales, illuminated displays, and various pointer reading angles. Models include indicators with multiple measuring systems for coarse and fine indication, and special-purpose indicators for cranes, excavators, ships, and offshore facilities.

Specifications: The document provides detailed specifications for measuring systems, including degree of protection, input values, and electrical data. Key specifications include resistance, current, and voltage inputs, accuracy of ±0.5% to ±0.1%, pointer angles up to 360°, and setting times of approximately 1 second. The temperature range for operation is -30°C to +70°C.

Mechanical Data: Casing materials include plastic and steel sheet, with degrees of protection ranging from IP 10 to IP 54. The document lists dimensions for various panel cut-outs and large format indicators.

Applications: Examples of applications include coordinate displays for platform inclination, high precision indicators for weight indication, double indicators for rail vehicle speed, and heeling angle indicators for shipload position.

Additional Features: Options for data storage, dial illumination, and various input types (e.g., wind direction, valve position) are available. The document also provides contact information for Fernsteuergeräte, the manufacturer.
