Digital / Bargraph Meters
Meter Types LE54D, LE90D, LE120D
The SIFAM range of solid state bargraph panel indicators is ideal where trend or percentage ratings are required in low light conditions. Such applications include process plant and vehicle control panels where vibration is present and stable readings required. All displays are assembled to customer's requirements, enabling single or mixed colours to be used for either cosmetic purposes or to give an instant indication of a change in monitoring conditions. The printed dial gives the added advantage of an analogue meter presentation.
Features and Benefits
- Choice of 3 DIN case sizes
- Stackable
- Solid State LED display with virtually instantaneous response
- Suitable for rugged and low light applications
- Standard red display with optional green and yellow which may be mixed
Displays
High intensity LED with optional dimming with external potentiometer. Red is standard, but green and yellow can be supplied as single or mixed colour. LE54D 54 segments in single column. LE90D 90 segments in single or dual column. LE120D up to 120 in a single arc with set position.
Dials
Can be scaled to customer requirements
