149-400 Gas Density Monitor with Remote Output
Brand: Qualitrol CompanyProvides local mechanical indication of levels of SF6 gas as well as 4-20 mA Analog remote output.
Unit automatically compensates for gas pressure changes due to ambient temperature.
Offers alarm and limit control with up to three factory set relays.
Features- Large dial face with many standard and custom displays for clear visual indication of the SF6 gas density
- Temperature compensated indication provides most accurate monitoring of gas levels within the tank
- Measurement accuracy of ±2% of full scale
- Visual indication of SF6 levels may be seen on the manual dial face of the instrument
- 4-20 mA Analog output for integration into a SCADA system
- 3 Form A relays may be triggered when the density level drops below a pre-defined value
- Stainless steel and brass external parts offer protection against harsh environmental conditions
- Vented case with UV stabilized polycarbonate lens is moisture intrusion resistant
