OBAI-3051C DP Intelligent monocrystalline silicon differential pressure transmitter
Product Related Description
Product Overview
OBAI-3051C DP intelligent monocrystalline silicon differential pressure transmitter is a high-precision, highly stable, multi-parameter pressure measurement product that complies with the HART protocol. The digital technology used in this product is the latest application achievement in the field of sensor manufacturing. It combines the internationally advanced single crystal silicon core design and manufacturing technology to perform precise digital temperature compensation and non-linear 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. HART375 handheld communicator can be used for digital communication, and electromagnetic radiation complies with IEC801 standards.
