CF2318 Intelligent Direct Connected Liquid Level Transmitter

Overview

CF2318 seriesLevel transmitterUsing high-precision and high stability diffusion silicon pressure sensing components, the liquid level signal of the measured liquid is converted into a 4-20mADC standard electrical signal through a highly reliable amplification circuit and precise temperature compensation. High quality sensors, exquisite packaging technology, and sophisticated assembly processes ensure the excellent quality and optimal performance of this product. This product is a split structure type and has two types of medium measurement: cable and anti-corrosion agent. Anti corrosive products can resist the erosion of various corrosive liquids and meet the needs of customers to the greatest extent possible. The CF2318 series liquid level transmitter products are divided into two types: ordinary type and intrinsic safety explosion-proof type. Explosion proof products can be widely used in various harsh and dangerous places in industrial sites.
