1, 3351 intelligent capacitor transmitter introduction

3351 Intelligent capacitor transmitter is the most widely used in foreign countries, the most mature technology capacitive sensor core, and the introduction of a full set of foreign production technology and technology, strict implementation of the quality management system 9001:2000 standard, the production of the latest series of pressure/differential pressure transmitter. Product modular design and full patch packaging, a number of exquisite unique plastic mold with advanced laser engraving means, making the product more compact and perfect.

3351 Intelligent capacitor transmitter for different domestic user requirements, intelligent series through the local button, the field can be reset or re-calibrate the range, through the hand device or communication software can also realize passive calibration and data configuration. According to the special needs of users, the intelligent series can reach the maximum wide range ratio (100:1) and high precision (0.075%).
