US firm launches water in fuel sensor


New sensor is said to detect the presence of water in fuel and lubricating oil.

US manufacturer Gems Sensors & Controls (Gems), a provider of liquid level, pressure, and flow sensors, miniature solenoid valves, and fluidic systems, has launched a new conductivity based sensor to detect the presence of water in fuel and lubricating oil within a broad range of applications.

The WIF-1250 is specifically designed to detect the presence of water in fuel. It is also said to be ideal for use with fuel filters, and in compressor crank cases to determine if water is present in lubricating oil.

Based on conductivity technology, WIF-1250 sensors are built from robust nickel plated steel for compatibility with temperatures up to 257°F (125°C), and are said to be suited for the most challenging environments or applications.

According to Gems, the compact sensor is an affordable solution that is easy to install and can be mounted in any position.

The WIF-1250 is a solution that contains integral, high-temperature-rated electronics that generate an alternating voltage to a probe tip. The presence of water completes the circuit which, in turn, changes the condition of the transistor output.

Output options vary and can be used to actuate relays, indicator lights or LEDs, as well as to interface with CMOS/TTL logic, PLCs or microprocessors. Product approvals include CE and RoHs, and sensors are available in 1/4” NPT and M12 mountings for applications around the world.
