Display type EEM MOT 01 FE01.01

This instrument presents basic engine parameters: engine speed, inlet air pressure, oil pressure, and oil temperature.

The casing is made of anodised aluminium. The LCD display is protected by high quality acrylic cover with anti-glare coating. This makes the device durable and easy to maintain.

The readings are displayed in both digital and graphical form. For immediate recognition of the status, colour codes are used. If the air speed stays within the desired range, the instrument displays values in green. If the warning threshold is crossed, the instrument informs the pilot by changing the colour of graphs and digits to orange. If alarm levels are reached, the digits and graph bars turn red. The threshold values (both upper and lower) are to be defined by the buyer at placing an order.
