Ưu điểm kỹ thuật quan trọng
-
Remote Transmitter Flexibility: The separate transmitter housing can be installed up to 300 meters from the sensor using standard cabling. This maximizes operational safety by keeping the user interface away from hazardous process conditions or extreme temperatures.
-
Integrated Multivariable Sensing: The G 500 directly measures volume flow, pressure, and temperature within a single device. It uses this real-time data to calculate mass flow and energy content internally, eliminating the need for external compensation equipment.
-
Insensitivity to Wet Gas: The sensor’s acoustic path and mechanical design are specifically engineered to remain reliable in the presence of moisture or condensate. This makes it an ideal solution for “green” or raw natural gases that have not been fully dehydrated.
-
Enhanced Safety with Rupture Disc: To mitigate risks in high-pressure gas applications, the sensor features a pressure-rated housing with an integrated rupture disc. This provides a controlled safety vent in the event of a primary seal breach.
-
Advanced Digital Connectivity: The transmitter supports up to 4 freely combinable Inputs/Outputs (I/Os), allowing for complex integration with control systems. It also features a built-in web server and WLAN access for wireless configuration via tablet or smartphone.
-
Heartbeat Technology: This suite provides continuous self-monitoring and allows for traceable verification of the device’s health without process interruption. It significantly extends calibration intervals by providing documented proof of sensor performance.
