RKC's LT1 is a back-pressure level switch for upper/lower limit liquid sensing. There are no moving mechanical parts, just a back-pressure sensor and built-in orifice to supply gas. A single tube handles liquid level alarm and sensing. The LE100/110 high-accuracy linear meter series can measure liquid levels in single and multiple chemical baths or as a pressure sensor. The built-in back-pressure sensor in the 1/16th DIN microprocessor can measure levels up to 1,000 mm. The front panel display has two digital readings for actual level and set value, up to eight level set points, and four push buttons for setting the unit. A single-touch setup can do empty adjustment, span adjustment, and automatic specific gravity computation, and a built-in linearizer compensates for variations in tank shapes. The meters display units such as millimeters, percent, liters, and milliliters. They have a repeatability of ± 0.3 percent of full span, and a 0.2-second sampling time.

The word “smart” is becoming the dumbest word around. It has been applied to almost every device and system in our homes. In addition to smartphones and smart meters, we now hear about smart clothing and smart shoes, smart lights, smart homes, smart buildings, and every trendy city today has its smart city project. Just because it has a computer inside and is connected to the Web, does not mean it is smart.
Are you being paid enough? Do you want a better job? According to a recent survey Manpower released just before Engineers Week, employers and engineers don't see eye-to-eye about the state of US engineers' skills and experience.
