　　Princo Instruments, Inc. was a premier manufacturer of industrial level control instruments,

　　specializing in RF capacitance level technology. The company’s NULL-KOTE? technology has proven to

　　be effective in eliminating the effects of product build-up on sensing probes where other

　　technologies have failed. The technology has proven effective in measuring the levels of water-based

　　liquids, acids, hydrocarbons and solvents, powders and granulars and various other chemicals.

　　Princo仪器公司是控制仪器的制造商，专门从事RF电容水平技术。该公司的Null KoTe技术是有效的消除产品积累

　　对传感探针的影响，在其他技术已经失败。该技术已被证明是有效的测量水基液体，酸，碳氢化合物和溶剂，粉末

　　和颗粒和各种其他化学品的水平。

　　Princo Instruments, Inc. originated as The Precision Thermometer and Instrument Company in 1910.

　　It was founded in Philadelphia by several employees who had previously worked for the Queen

　　Thermometer Company. The company is privately held and is still owned and operated by the family of

　　one of the original founders.

　　Princo仪器公司起源于1910精密温度计和仪器公司。

　　In the period from 1910 through World War II the company manufactured a variety of instruments, most

　　of which were made from glass and contained mercury as the measurement medium. These included

　　laboratory thermometers, dial thermometers, metal cased industrial thermometers, thermostats,

　　mercurial barometers, manometers, and vacuum gauges.

　　在1910至二战期间，该公司制造了各种仪器，其中大部分由玻璃制成，并含有汞作为测量介质。这些仪器包括实验

　　室温度计、刻度温度计、金属外壳工业温度计、恒温器、水银气压计、压力计和真空计。

　　In 1962, the company moved from Philadelphia to its present location in Southampton, Bucks County,

　　Pennsylvania.

　　在1962，该公司从费城转移到现在的位置在南安普顿，巴克斯郡，宾夕法尼亚。

　　In the early 1970’s, an electronic level control was added to the company’s process control line.

　　From this early vacuum tube level switch Princo has developed a complete line of RF Impedance level

　　instruments. As the demａnd for mercury-based measurement devices declined, Princo gradually

　　transformed itself into a company concentrating on electronic level controls.

　　在1970年初，一个电子水平控制被添加到公司的过程控制线。从这个早期真空管水平开关Princo已经开发了一个完

　　整的射频阻抗水平仪设备。随着对基于汞的测量设备的需求下降，Primo逐渐转变为一个于电子水平控制的公司。
