overview

The LH series pressure (differential pressure) transmitter uses imported high-quality diffusion silicon and ceramic pressure sensors as sensitive components, and adopts a dedicated integrated module. Through fine temperature, zero point, full range, and nonlinear compensation, it achieves accurate measurement and transmission of pressure changes in liquid, gas, steam and other media. Realize ideal monitoring of pressure and vacuum medium changes in various places by industrial and mining enterprises, research institutes, and other departments.

characteristic

★ Dedicated V/I integrated circuit, with few peripheral components, high reliability, simple and easy maintenance, small size, light weight, and extremely convenient installation and debugging.

★ Aluminum alloy die-casting shell, three end isolation, electrostatic spray protection layer, sturdy and durable.

★ 4-20mADC two-wire signal transmission, strong anti-interference ability, and long transmission distance.

★ LED LCD、 The pointer has three types of indicator heads, making on-site reading very convenient. Can be used to measure viscous, crystalline, and corrosive media.

★ High accuracy and stability. In addition to the imported original sensors that have been laser corrected, the comprehensive temperature drift and nonlinearity of the entire machine within the operating temperature range are finely compensated, resulting in small nonlinearity and good temperature stability within the operating temperature range.
