Gas Phase Monitoring Sensor

Name: Gas Phase Monitoring Sensor
SKU: 0

Dry-Wet Sensor (Model: LDA-1): During the fuel loading process, the dry-wet sensor continuously detects whether there is liquid in the gas phase crane pipe. Interlocked with the process controller, when liquid is detected, the process controller will sound an alarm, and interlock control will stop the fuel loading operation.

Product Introduction：

1. Dry-Wet Sensor (Model: LDA-1): During the fuel loading process, the dry-wet sensor continuously detects whether there is liquid in the gas phase crane pipe. Interlocked with the process controller, when liquid is detected, the process controller will sound an alarm, and interlock control will stop the fuel loading operation.

2. Ex-proof Flow Switch (Model: FM-A1): The explosion-proof flow switch can detect the oil and gas flow in the gas phase crane pipe during the fuel loading process, and output a general dry contact signal, which is transmitted to the batch controller, PLC, and process controller. During fuel loading, if no oil and gas flow is detected in the gas phase crane pipe within the expected time, the explosion-proof flow switch will output a relay signal, indicating an anomaly, and the corresponding host computer will output an alarm signal.
