Differential Pressure Transmitter

Differential Pressure Transmitter
Product Detailed
1.Excellent performance; 2.Multi sensor; 3.Compensation

Pressure Transmitter

Brief Introduction

As a new generation of smart fieldbus pressure transmitter, NCS-PT105II series pressure transmitter with capacitance sensor 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
