Gas Density Transmitter – 10F

Description

The gas density transmitter is electronically compensated. The compensation follows the nonlinear behavior of SF6 gas. The basic principle is the calculation following virial equation. The gas density transmitter picks up the physical variables pressure and temperature of the SF6 gas contained in the device (tank). The current gas density is ascertained from both variables by means of an electronic evaluation system. Thermal induced pressure changes are dynamically compensated and do not affect the output signal.

The gas density transmitter generates a density proportional, standardized signal of 4 … 20 mA.

A recalibration of the zero signal as well as maintenance service will no longer be necessary due to the high long-term stability of the gas density transmitter.
