CF2001 Intelligent Direct Connected Pressure Transmitter

Overview

The CF2001 series absolute/pressure transmitter uses high-precision and high stability diffusion silicon isolation sensor components. Through highly reliable amplification circuits and precise temperature compensation, the absolute or gauge pressure of the measured medium is converted into a 4-20 mA DC standard electrical signal. Exquisite packaging technology and perfect assembly process ensure the excellent quality and optimal performance of this product. This product has the characteristics of complete variety specifications, standardized interface forms, and convenient zero and range adjustment, which can meet the needs of customers to the maximum extent. The CF2001 series of absolute pressure/pressure transmitter products are divided into three types: ordinary type, intrinsic safety explosion-proof type, and explosion-proof type. Intrinsic safety explosion-proof and explosion-proof products can be widely used in various harsh and dangerous places in industrial sites.
