Product Description



Brief Introduction

As a new generation of smart fieldbus pressure transmitter, Capac capacitive itive LCD display differential pressure transmitter is available on FF H1, Profibus PA and HART protocols. The Transmitter has high accuracy, better reliability and intrinsically safety.


1.Excellent performance:

High accuracy: ±0.075%(20°C, range rate 10:1)

Stability: ±0.1% of maximum range per year

High range rate: 100:1

2.Multi sensor: differential pressure (SD), high static pressure (SH), gauge pressure (SG), absolute pressure (SA), micro differential pressure (SR)

3.Compensation: automatically environmental temperature compensation
