Protran ® PR3860 High Temperature Pressure Transmitter
Technical DataDescription
The PR3860 high temperature pressuretransmitter has been designed to meet therequirements of the majority of industrial pressure
measurement applications where a hygienic ﬂush
diaphragm connection is required.

accurate output signal of 4-20 mA with options for 0-5 Vdc,
0-10 Vdc and other output signals. Electrical connection is via
a detachable DIN connector allowing easy access to zero andspan adjustment. Pressure ranges available from 0-10 bar to0-400 bar.

Robustly constructed from stainless steel, the PR3860
pressure transmitter permits accurate pressure measurement
at elevated temperatures. Output options include 0-5 Vdc,
0-10 Vdc and 4-20 mA. This transmitter is suitable for use atmedia temperature up to 250 ºC. Typical applications include
