Introtek has released its new MEC series microelectronic circuitry complimenting its existing line of air bubble, air-in-line and liquid level detection sensors and electronics.
Introtek has released its new MEC series microelectronic circuitry complimenting its existing line of air bubble, air-in-line and liquid level detection sensors and electronics.
The MEC uses Introtek's patented noninvasive pulse-type ultrasonic technology.
The MEC operates in conjunction with the company's sensor assemblies to detect air, bubbles, foam or liquid level in various tubing and vessels in the most critical applications.
At the heart of the MEC is a programmable microcontroller which allows for custom tailored functionality specific to any application.
The MEC circuitry is small enough that it can be located internally in an Introtek BDF series sensor head, thus allowing for a compact integral sensor assembly.
The board measures just 16.2 x 23.1mm and runs from a single 5V DC supply.
Current consumption is 15mA without LED, 24mA with LED.
The digital output signal is CMOS compatible, programmable for high or low on wet.
A self-test feature provides an electronic check for false wet output signals.
Maximum response time for bubble detection (wet to dry) is 215us, for liquid detection (dry to wet) is 46ms.
