DURO
Pertanyaan yang Sering Diajukan
Pertanyaan umum tentang DURO dari 3G Electric.
What materials are used in DURO gauge wetted parts and casings?
DURO industrial gauges feature all-stainless steel wetted parts and casings. The wetted parts—those in contact with the process media—are made from stainless steel, providing resistance to corrosion from water, chemicals, and many industrial fluids. The case material is also stainless steel, which protects the internal mechanism from environmental moisture and mechanical damage. This construction makes DURO gauges suitable for applications where brass or other materials would degrade, such as in chemical plants, offshore platforms, or food processing facilities.
What accuracy class do DURO pressure gauges meet?
DURO pressure and compound gauges are rated with an accuracy of ±0.5% of full scale. This means that for a gauge with a 0 psi to 300 psi range, the reading is accurate within ±1.5 psi. This accuracy level is typical for industrial process gauges and is suitable for monitoring and control applications where moderate precision is required. It is not a calibration-grade or test-gauge accuracy, but it meets the needs of most plant engineering and maintenance tasks.
What pressure ranges and dial sizes are available for DURO gauges?
DURO gauges are available in pressure ranges from 0 psi to 60 psi up to 0 psi to 400 psi, including compound ranges that measure both vacuum and positive pressure (e.g., 0 psi to 100 psi compound). Dial sizes include 4 1/2 in and 6 in diameters. The 4 1/2 in dial is common for direct-mount applications, while the 6 in dial is often used in panel-mount configurations for better readability at a distance. Connection sizes are 1/4 in NPT male or 1/2 in NPT male, with bottom or back-flange mounting options.
Does DURO offer gauges with a red max hand for peak pressure indication?
Yes, DURO produces models with a red max hand, such as the MPN 42070413-MAXHAND and MPN 42070713-MAXHAND. The red max hand is a secondary pointer that remains at the highest pressure reached during operation, allowing maintenance personnel to identify pressure spikes or overpressure events after the fact. This feature is useful for troubleshooting and system monitoring without requiring continuous observation. The max hand is reset manually by turning a knob or pressing a button on the gauge face.
What mounting options are available for DURO gauges?
DURO gauges are offered in two primary mounting configurations: bottom connection and back-flange panel-mount. Bottom-connection gauges have a 1/4 in or 1/2 in NPT male fitting at the bottom for direct pipe mounting. Back-flange panel-mount gauges include a flange on the back of the case for flush installation into a control panel, with the connection also at the bottom. The back-flange design allows for secure panel mounting and is common in centralized monitoring stations.
Are DURO gauges suitable for vibration-prone environments?
Some DURO gauge models are specified with vibration resistance properties, while others are not. For example, the back-flange panel-mount models (MPN 6.2020913E7, 6.2020413E7, etc.) list vibration resistance properties as 'None' in their specifications. For applications with significant vibration, such as near pumps or compressors, engineers should select gauges with built-in vibration damping or use external isolation mounts. 3G Electric can advise on available options based on the specific operating conditions.
