Ex-proof Rousemount 2088-R Absolute / Gauge Pressure Transmitter
 
R-2088-Series with 4-20mA + HART output and digital display 
PKR. 28,600.00 each.
 
1.Description
EX-proof Pressure Transmitter is designed for applications which deal with corrosive pressure media and require high accuracy. The pressure diaphragm of this transmitter is made from silicon material, while its wetted parts are made from 316L stainless steel which possesses a higher degree of resistance against chemical corrosion.

The output signals are configured to meet the need of different controllers used in industrial automation processes, including 4~20mA, 1~5V  It can obtain 0.25 %accuracy in measurement with long-term stability better than 0.15 %/year. The zero thermal drift is less than 0.075 % fso/°C, while the sensitivity thermal drift is 0.05 %/°C over the whole operating temperature range.
 
• Performance of 0.075% with High Accuracy
option
• Lightweight, compact design for cost effective
installation
• Protocols available include 4-20 mA HART®
and 1-5 Vdc HART Low Power
• Absolute and gage pressure ranges up to
4,000 psi (276 bar)
• Rangeability of 20:1
 
 
This transmitter features integrated construction,rigid and robust,high measuring accuracy,good long term stability,and it is suitable for pressure measurement in general industry applications,including but not limited to petroleum,chemical,metallurgy,power station and hydraulic etc industries.
