DESCRIPTION
The PR3890 pressure transmitter has been designed primarily for use on concrete slurry and other abrasive
media.
To meet the demanding requirements of this application, tough and highly abrasive resistant materials are used
throughout the design. A specially designed ceramic sensing element protected in a robust 316L stainless steel
housing provides a robust solution. The sensor face is then cushioned by a replaceable polyurethane wear
membrane, which protects against imPACts caused by solids suspended in the liquid media.
The process connection is a proprietary design providing crevice free flush mounting into a 4 inch diameter welded
pipe boss. Output signal is standard 4-20mA, 2wire, with loop supply range from 10 to 32Vdc. Operation on a
12Vdc battery system is permitted. Pressure ranges are available from 0-6 bar to 0-100bar.
Cable entry is through a sealed nylon gland for sizes form 4-8mm diameter. Electrical connections are made to 2
screw terminals and will accept conductor size 0.1 to 2.5mm2. These and the zero and span adjustment
potentiometers are accessible by removing the cable outlet cover.
Applications for the PR3890 include pressure control systems on concrete pumping equipment and general
pressure measurement of abrasive media in industrial processes.
