Transformer Remote Contact Buchholz Gas Relay - Reliable Control
Buchholz Gas Relay with Remote Contact
The Gas Relay Gas Volume Sensor is designed to enable real-time monitoring of gas accumulation within gas (Buchholz) relays. This product accurately and linearly detects both the volume and rate of gas accumulation, transmitting the data via 4–20mA analog output or RS485 (MODBUS) communication. It provides a solution for continuous, linear measurement of gas levels—a capability previously unavailable in conventional monitoring systems.
Remote Monitoring Buchholz Gas Relay Features
1. The sensor is mounted directly on the viewing window of the gas relay, enabling real-time monitoring of internal gas accumulation.
2. It requires no modifications to the existing relay structure or operation, ensuring seamless integration.
3. All power and signal connections are facilitated through the sensor’s junction box for straightforward installation.
4. The sensor supports both 4–20mA analog output and RS485 (MODBUS protocol) communication for flexible data integration.
