Analog Display Units with Stepping Motor Type EAD
With the device series type EAD, the Dr. E. Horn GmbH & Co. KG presents analog display units with stepping motor drive with the front panel cut-out dimensions of 72 x 72 mm, 96 x 96 mm and 144 x 144 mm.
These devices differ from conventional moving-coil measuring instruments by the robustness of the pointer drive, a possible pointer deflection of 360 °, the better readability in difficult conditions, as scales and pointers are illuminated and the possibility of integrating the scoreboard in fieldbus systems.
Unlike the conventional moving-coil measuring instruments the EAD indicator can be used in any position. The linearity is ± 0.5% of full scale. The construction of the device enables the processing of all standard input signals such as CAN bus, -10 – 0 – +10 VDC, 04/12/20 mA, potentiometer, etc. When connected to the CAN bus, the devices are centrally controllable from a master. The zero point calibration is carried out on-site by using a button. Optionally there is a signal output from 4 – 20 mA for further signal analysis. The LED lighting of scale and indicator can be dimmed.
Approvals of Classification Societies (wheelmark) are available.

Speed Indicator Type EA

For the remote speed measurements besides tachogenerators display units are needed. HORN speed indicators are robust, maintenance-free, tested in extremely harsh operating rotary coil instruments with high accuracy. They are available as round instruments for flush and surface mounting – supplied in rectangular and square design – especially for panel mounting. For use on installation locations that are exposed to the elements, preferably on ships, the speed indicators with a weatherproof and seawater-resistant light metal housing are designed.
