OBAI-800M/X Flange diaphragm level transmitter
Product Related Description
Product Overview
OBAI-80OM/X flange diaphragm level transmitter is a high-precision, highly stable, multi-parameter pressure/level measurement product that complies with the HART protocol. This product uses advanced microprocessing technology and digital communication technology to perform precise digital temperature compensation and nonlinear correction. LCD 4.5-digit display, standard signal output, and full diaphragm covering the sealing surface, which can meet the on-site detection of various corrosive media. Reliable explosion-proof structural design and standardized signal output, high accuracy and wide range coverage, suitable for precise measurement of fluid pressure. HART375 handheld communicator can be used for digital communication, and electromagnetic radiation complies with IEC801 standards.
