Type 3351AP absolute pressure transmitter

1151/3351AP type absolute pressure transmitter can be realized on the gas removal system, distillation tower, evaporator and mold and other equipment in the absolute pressure measurement, allowing the pressure in the 10Mpa. The absolute pressure transmitter is tested on one side of the absolute pressure transmitter, and the other side is sealed into a high vacuum reference chamber, which is then converted to 4 ~ DC 20mA signal output.

Including GP type pressure (including negative pressure) transmitter, AP type absolute pressure transmitter. Above two kinds of transducer and intelligent put plate combination, can be in the form of intelligent pressure transmitter, it can be in accordance with HART protocol manipulator mutual communication, setting up and monitoring.

1151 series miniaturization capacitive pressure / differential pressure transmitter is my company to introduce advanced foreign technology and equipment for the production of the new transmitter and key raw materials, components and parts are imported, machine through strict assembly and test, the product has advanced design principle, the variety specification is complete, installation is easy to use. Due to the appearance of the model is fully integrated with the most popular in the country, and is widely used in the structure of the two kinds of transmitters, give users a fresh feeling. At the same time with the traditional 1151, CECC and other products in the installation can be directly replaced, there is a strong versatility and alternative capacity. In order to adapt to the continuous improvement of the level of domestic automation and development, the series of products, in addition to the design of compact and delicate, but also launched with the HART Fieldbus Protocol Intelligent functions.
