Press Release Summary:
With no moving parts, T/LL140 measures liquid depth by changes in capacitance. Intelligence enables unit to self-calibrate, in situ, and function equally with bio or red diesel fuel alternatives as well as fuel additives. Sensor can output signal in resistance, voltage, or PWM mode, and stem can be cut by user to suit individual tank requirements. Rated to IP67 and suited for temperatures from -20 to +85ºC, product includes option to use fuel feed and return pipes.

Fozmula's New 'Intelligent' Capacitance Sensor Gets the Measure of Fuel Levels
Maintaining its reputation as one of the most innovative manufacturers of fuel sensors and switches, Leamington Spa based Fozmula has now developed its advanced T/LL140 'intelligent' capacitance sensor.
The brilliant new T/LL140 is uniquely designed to answer the demands for a more flexible and efficient method of measuring fuel levels where both the types and qualities of fuel and fuel tank configurations make conventional measuring devices awkward or just difficult to use.
There are no moving parts because liquid depth is measured by changes in capacitance, governed by the unit's inbuilt intelligence, which enables it to self calibrate, in situ, and to function equally effectively with bio or red diesel fuel alternatives or with fuel additives. And, of course, with such clever technology, it is perfectly suited for telemetry applications which monitor remotely the contents of the fuel tank. This can then calculate fuel usage and detect any sudden loss.
The T/LL140 is not only clever, it is also extremely versatile. Designed and manufactured to a high specification it offers ease of maintenance characteristics and can be deployed in demanding operating environments including off-road and rough-terrain vehicles and boats, industrial machinery, compressors, generating sets, awkwardly situated static fuel tanks and mobile lighting towers.
Furthermore, the sensor can output its signal in resistance, voltage or PWM mode to suit the engine management system.
One of the primary features of the T/LL140 is its sensor stem which can be cut by the user to suit individual tank requirements. The cut-to-length concept may seem simple, yet the overall benefits, such as reduced stocking levels, makes this a very desirable, efficient and truly effective sensor in a massive market that demands this kind of technology with this kind of practicality.
Intended to be many things to as many design engineers as possible, the T/LL140 also includes the option to use fuel feed and return pipes. These can be fitted with customer specified tube diameters and fixed or swivel type tube fittings.
Key Features include:
The T/LL140 has no moving parts making it ideal for use in high level vibration, fluid turbulence or where there is a likelihood of contaminating solids, an inherent problem where conventional swing arm and stem float sensors frequently fail.
The T/LL140 has the intelligence to self-recalibrate automatically for different fluid types (oil, diesel, bio-diesel etc) and for different tank shapes including round, saddle- shaped and cylindrical.
The T/LL140's electronics are such that an alarm switch can be set at any point along the sensor stem to operate a warning light or alarm, or to operate a pump or to send a signal.
The T/LL140 sensor stem can be cut to any desired length by the user with no detrimental effects on performance. Practical and convenient when it comes to efficient stock control.
The T/LL140 is extremely robust, complies with sealing requirements to IP67 and functions in low and high temperature (-20ºC to +85ºC) environments. It has been vibration and EMC tested to international standards.
The T/LL140 can be adapted for special projects including fuel feed and return pipes and special connections (e.g. flying leads, customer specified connectors etc). A 5 holes SAE flange fitment configuration is provided as standard.
Typical Applications:
Generating Sets where a tough, robust sensor must be resistant to surrounding electromagnetic radiation.
Off-road and Rough-terrain vehicles and boats where high levels of vibration and constant rapid and irregular movement is evident.
Awkwardly situated static fuel tanks where access is difficult making long term reliability a necessity.
Industrial compressors which are frequently housed in hot environments and run continuously for long periods.
Mobile lighting towers in various locations such as remote car parks, building and road construction sites and where vibration and extreme weather conditions can cause problems for sensors and electronic components.
The T/LL140 'intelligent' capacitance fuel level measurement sensor sets new standards for the industry.
