QZ3351 series capacitive absolute pressure transmitterDetailed product description：

Product Introduction

The QZ3351 series capacitive transmitter not only inherits the advantages of the classic 1151 transmitter, but also has a smaller size, lighter weight, and higher accuracy. This product includes multiple varieties and specifications such as differential pressure, gauge pressure, absolute pressure, negative pressure (vacuum), flange liquid level, and remote transmission flange. Its options, signal system, and installation method are completely consistent with those of other famous companies in the world.
This product is divided into three types: ordinary type, explosion-proof type, and intrinsic safety type. Users can choose according to the actual requirements on site.
