SF6 gas transmitter GD10-C, GD10-L

2-wire

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. Applications Gas density monitoring of closed SF6 tanks For indoor and outdoor installation in SF6 gas-insulated switchgear Special Features Measuring ranges from 0 ... 10 to 0 ... 80 g/litre Output signal 4 ... 20 mA, 2-wire Wetted parts and case made of stainless steel, fully welded Ingress protection IP 54 up to 68, depending on the electrical wiring Excellent long-term stability, high EMI performance
