Trafag 8739 Hybrid Gas Density Monitor with Contacts and Modbus Output

The Trafag 8739 combines a reference gas density monitor with an oscillating quartz sensor. It gives SPDT switching contacts for alarms and RS485 Modbus (RTU) output for continuous digital density data.

It measures from 0 to 1300 kPa absolute at 20°C, or 0 to 60 kg/m³, across a -40°C to +80°C operating range. Fully temperature compensated and suitable for indoor and outdoor use.

Designed for medium voltage switchgear running SF6 or alternative mixed insulation gases. Swiss made by Trafag AG.
