HP3351 DP/GP remote transmission differential pressure/pressure transmitter

Overview

HP3351 DR/DPdifferential pressure/After the pressure transmitter is equipped with a remote transmission sealing device, it becomesHP3351 DP/GPRemote differential pressure transmission/Pressure transmitter, it still hasHP3351 DR/DPdifferential pressure/Various characteristics of pressure transmitters.

The capacitive pressure transmitter is a new type of transmitter produced by our company through the introduction of advanced foreign technology and equipment. The key raw materials, components, and parts are all imported, and the whole machine has undergone strict assembly and testing. This product has the characteristics of advanced design principles, complete varieties and specifications, and easy installation and use. Two widely used transmitters(Rosemount3051Along with YokogawaEJA)The structural advantages provide users with a refreshing feeling. Simultaneously with traditional1151TheCECCThe series of products can be directly replaced during installation, with strong versatility and substitutability. In order to adapt to the continuous improvement and development of domestic automation level, this series of products not only has a compact and exquisite design, but also introduces products withHARTThe intelligent function of fieldbus protocol.

purpose

Remote differential pressure transmission/Pressure transmitters can avoid direct contact between the measured medium and the isolation diaphragm of the transmitter. This measurement method is suitable for the following situations:

1The tested medium has a corrosive effect on the sensitive components of the transmitter

2It is necessary to isolate the high-temperature measured medium from the transmitter

3There are suspended solids or high viscosity media in the tested medium

4The tested medium is easily solidified or crystallized when introduced through a pressure tube

5The replacement of the measured medium requires strict purification of the measuring head

6The measuring head must be kept hygienic and contamination is strictly prohibited

7Object of use: Corrosive or viscous liquids

Attention: Remote transmitters should not be used in vacuum environments
