Massa Products recently released the M-300 family of ultrasonic sensors. These RoHS-compliant, non-contact distance measurement sensors feature user-controlled outputs and the ability to be set up without using a target.
M-300 sensors transmit sound pulses at a rate controlled by the user or software and then process the return echoes. These sensors use Windows-compatible software using an RS-232/RS-485 or USB/RS-485 converter and can be controlled through an RS-485 data link.
These sensors operate from 12 to 24V DC, have a linear output of 0 to 10V DC, and are constructed of a PVC housing with a 1-inch standard NPT fitting. Detection for this sensor family ranges from 4 inches to more than 15 ft and operates from -20°C to 65°C.
M-300 sensors feature built-in temperature compensation, monitoring and diagnostic outputs. Variable adjustments include analog output slope, sampling rate, averaging of multiple distance measurements, loss-of-echo time-out and more. Applications include liquid level control, mechanical positioning, roll diameter measurement, web loop monitoring, automatic filling operations, automatic packaging, bulk level control and paper/plastic film processing.
The Massa M-300 features a standard 1-inch NPT fitting.
A new service lets engineers and orthopedic surgeons design and 3D print highly accurate, patient-specific, orthopedic medical implants made of metal -- without owning a 3D printer. Using free, downloadable software, users can import ASCII and binary .STL files, design the implant, and send an encrypted design file to a third-party manufacturer.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
