Product Related Description
Product Overview
OBAl-800 intelligent universal pressure transmitter is a high-precision, high-stable, multi-parameter pressure measurement product. The digital technology used in this product is the latest application achievement in the field of sensor manufacturing. It is combined with internationally advanced piezoresistive pressure transmitter design and manufacturing technology to perform precise digital temperature compensation and nonlinear correction. LCD 4.5-digit display and standard signal output can meet various observations on site and in the control room. Reliable explosion-proof structural design and standardized signal output, high accuracy and wide range coverage, suitable for precise measurement of fluid pressure. Widely used in industrial process control, hydraulic equipment, chemical industry and other industries.
