Capacitive point level fuel sensor

What liquids can the Universal Level Sensor detect?
The Universal Level Sensor can sense aqueous, oil, and hydrocarbon liquids.


How is the Universal Level Sensor affected by coolant coating the sensor element?
The PBT/PC blend sensing element designed to resist coating and build-up due to the smooth surface material and flush sensing face.


Will foam or bubbles affect the Universal Level Sensor?
The Universal Level Sensor will only sense bubbles or foam when it is dense enough to trigger the sensor (usually right at liquid surface). Light bubbles and foam further from the surface will be sensed as air and will not cause false signals.


How does the Universal Level Sensor handle sloshing or turbulence?
The Universal Level Sensor can be configured with a time delay on increasing level, decreasing level, or both. The sensor will not trigger as liquid present or as dry condition until after the configured delay has lapsed.


How is the Universal Level Sensor better than my float level switch?
The float type level switches are susceptible to build-up and mechanical failure over time due to having moving parts. The switching is usually done with an internal reed switch. This is also at risk of failure from normal wear and electrical damage. The Universal Level Sensor uses reliable solid state (no moving parts) electronic switching with an open collector.


What is an open collector output?
The open collector is an electronic solid state switch with no moving parts. It works with DC power and basically toggles the current flow from the output signal wire to ground. It has a base, a collector, and an emitter. The sensor signal is always the base leg, and current is either allowed or blocked from collector to emitter with the presence of liquid (depending on the configuration).


Can the Universal Level Sensor trigger a signal in either wet or dry condition?
The Universal Level Sensor can be configured in the factory to signal when the sensor element is wet or dry with optional time delays and either a sinking or sourcing circuit.


How do I choose between sinking or sourcing?
It all depends on how you wish to wire the sensing circuit. In a sinking configuration, current passes through the load first, through the output switch of the sensor second and lastly to ground. It is a transistor logic output that switches the DC ground, or negative, leg of the circuit. In a sourcing configuration, the load must be connected between the sensor output and the DC ground. With a sourcing sensor, your input voltage powers the load. It is a transistor logic output that switches the DC positive voltage. A sensor with a sourcing output switches the positive leg of the circuit.


Is the Universal Level Sensor suitable for outdoor use?
With its rugged durable stainless steel construction, glass reinforced PBT/PC blend sensing element, IP6K9K rating (direct-spray, wash-down), and wide temperature range, the Universal Level Sensor was designed to withstand the harshest outdoor environments.


I have limited space. Will the Universal Level Sensor work for me?
The Universal Level Sensor’s compact design consisting of a less-intrusive flush sensing element, and less than 3” overall length fits in the smallest footprint making it great for mobile applications.


I use float-type, electro-optic, and ultrasonic sensors on my equipment. Which sensors can the Universal Level Sensor replace?
Gems’ Universal Level Sensor encapsulates the best of what existing sensor types offer in a single sensor technology. It was designed to work with a wide variety of medias. It eliminates failure caused by moving parts. It works well in high viscous, high pressure, humid, and reflective applications. It does not rely on specific gravity and resists coating and build-up. Simplifying product selection and reducing inventory with ONE common sensor type to replace them all!
