Pressure and differential pressure instruments for industrial applications

Single-crystal silicon differential-pressure measurement with a proportional current output.
Select the measurement range, process connection and output configuration for your application.
The 2051 supports differential-pressure measurement and related liquid-level or flow applications. The instrument transmits a 4–20 mA signal, with a HART communication option. Diaphragm material and operating conditions should be checked together when selecting the final configuration.
