Overview

The negative pressure transmitter uses diffusion silicon and ceramic pressure sensors as sensitive components, adopts integrated modules, and achieves accurate measurement and transmission of pressure changes in liquid, gas, steam and other media through fine temperature, zero point, full range and nonlinear compensation. Realize ideal monitoring of pressure and vacuum medium changes in various places by industrial and mining enterprises, research institutes, and other departments.

Product Details

The 3851/1851GP pressure (including negative pressure) transmitter measures a small pressure of 1kPa (can be transferred to a negative pressure transmitter).
Target audience: liquids, gases, and vapors

Negative pressure transmittercharacteristic:
★ 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.
★Negative pressure transmitterAdopting a 4-20mADC two-wire signal transmission system, it has strong anti-interference ability and a long transmission distance.
There are three types of indicator heads: LED, LCD, and pointer, 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.
