Overview
LH series of pressure (differential pressure) transmitter proliferation of high-quality selection of import-type silicon, ceramics type pressure sensor as sensitive components, the use of Application Specific Integrated module temperature by fine, zero, full-range and non-linear compensation, the realization of liquid, gas, medium pressure steam, such as changes in the precise measurement and transmission. The realization of industrial and mining enterprises, research institutes and other departments of the various places of the vacuum pressure of the ideal medium to monitor the changes.
Features
★ dedicated V / I circuits, less peripheral devices, high reliability, maintenance is simple, easy, small size, light weight, convenient installation and debugging.
★ Die-casting aluminum alloy shell, three-terminal isolation, electrostatic spray protective coating, durable.
★ 4-20mADC second-line system for signal transmission, anti-interference ability, transmission distance.
★ LED, LCD, three indicator pointer head, the scene is very convenient reading. Can be used to measure the viscosity, crystallization and corrosive media.
★ high accuracy, high stability. In addition to import original laser sensors have been amendments, on the whole temperature range in the use of the integrated temperature drift, non-linear compensation fine, so in the use of non-linear small temperature range, good temperature stability.
