1. Product brief introduction

Seal diaphragm is a pressure sensor component that used to prevent process medium directly into the differential pressure transmitter, they are connected with the transmitter through filled with fluid in the capillary. diaphragm sealed differential pressure transmitter used to measure liquid, gas or steam flow and liquid level, density and pressure, and then transform it into 4 ~ 20 mA DC signal output.  pressure transmitter series support BRAIN, HART and FOUNDATION fieldbus PROFIBUS PA or communication protocol.


Excellent performance and stability:

This series uses a formed from monocrystal silicon, a perfect material which has no hysteresis in pressure or temperature changes. The sensor minimizes overpressure, temperature change, and static pressure effects, and thus offers unmatched long-term stability.


Compact and light-weight design:

Half the weight of conventional models thanks to miniaturization of the casing with the amplifier ASIC, pressure cell structure, and flange. The ASIC uses the minimum number of parts and improves the reliability of the amplifier.


Fieldbus communication capability:

Fieldbus is a digital twoway communication system. It is a revolutionary technology for configuring instrumentation control systems and a promising successor to the standard 4 to 20 mA analog communication used in most field instruments today.
