With Integrated Gas Density Transmitter
Modified bourdon tube pressure gauge with integrated Gas Density Transmitter inside the case
Model 233.52.100 TI features a Gas Density Transmitter integrated into the back of the case. It functions fully as a standard GD-10 Gas Density Transmitter, however, the combination allows for both instruments to obtain a density reading through a single connection to the tank.
The gas density transmitter is electrically compensated following the non-linear behavior of SF6-gas according to the virial equation. This provides the highest accuracy and best temperature compensation possible since SF6 is a real gas functioning according to real gas law equations. Only a gas density transmitter can take this into account.
The gas density transmitter picks up the 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.
Recalibration of the zero signal is not necessary due to the high long-term stability of the gas density transmitter. The hermetically-sealed measuring cell guarantees high longterm leak tightness. It is welded closed to prevent leaks and remain independent of atmospheric pressure fluctuations and variations of the mounting height.
The EMI properties of the transmitter are tested according to IEC 61000-4-2 thru IEC 61000-4-6 and guarantee a safe pick-up of the signal which is especially suited to conditions prevailing in high-voltage switching units.
