BELITE FUEL PROBE SYSTEM 1/4" PROBES

The Belite liquid level / fuel probe is designed to sense fuel or liquid level of any type and provide an electrical indication to instrumentation along a range of 0 to 5 volts. The unit is not TSO'd or PMA'd. Use only in appropriate aircraft as a backup to certified instruments and pilot calculations. Ideal for monitoring level of liquid in many other applications, such as agricultural spraying. Patent pending.

• Stainless steel construction, 304L
• High precision pressure sensor, accurate +/- 2% absolute
• No moving parts. Based on MEMS technology
• Designed to be immune to temperature, shock, and vibration
• Will not fail if water is present in fuel (unlike capacitive probes)
• Compatible with any tank size or depth to 48”
• Long term stability 0.5% per year
• Operating temperature range -40 to 100 degrees C (Probe Only)
• Compatible with 9 to 14 volts input power
• Provides linear output of 0.0 to 5.0 volts (empty / full)
• Built in exceptional slosh filtering and optional G filtering
• Includes five point calibration for empty, ¼, ½, ¾, and full tank
• Custom calibrations available. Contact factory.
• Alarm output active if <25% full. Contact factory for other alarm options.

• Provides liquid level indication between empty and full, for any tank with a minimum height of 6 inches (150mm) and a maximum height of 48 inches
• (1200mm).
• The electrical output of the product varies between 0.0 volts and 5.0 volts.
• Asserts “ALARM” when the tank is filled to less than 25% of calibrated capacity. Provides active low current sink to 15 ma.
• Includes an electrical slosh filter with an approximate time constant of 20 seconds.
• NOTE: if a tank was quickly evacuated due to a gross rupture or failure, the system may require up to one minute to fully reflect an “empty” condition.
• Parts included are Liquid Probe with pigtail, Electronic Control Module & 9V
• connector.

• Microprocessor with RAM & firmware
• Input A / D converter
