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.
Industrial workplaces are governed by OSHA rules, but this isn’t to say that rules are always followed. While injuries happen on production floors for a variety of reasons, of the top 10 OSHA rules that are most often ignored in industrial settings, two directly involve machine design: lockout/tagout procedures (LO/TO) and machine guarding.
