Core product features and technological advantages

1. Customized configuration, adapted to hazardous environments and precise monitoring requirements

This model has strengthened its scene adaptation configuration on the basis of basic functions: the equipped explosion-proof junction box (- J) can effectively isolate electrical sparks, meet the installation requirements of hazardous areas, and is suitable for scenarios with flammable and explosive media such as petrochemicals and oil and gas extraction; The adjustable filter regulator (- R) can filter impurities and moisture in the gas source, while stabilizing the gas source pressure and avoiding the impact of gas source fluctuations on conversion accuracy; The supply/output dual pressure gauge (- S) achieves real-time visual monitoring of gas source pressure and output pressure, and operation and maintenance personnel can complete pressure calibration and troubleshooting without the need for additional detection tools, greatly improving on-site operation and maintenance efficiency.

2. Wide range signal adaptation, flexible and adjustable action mode

The input signal supports three industrial standard DC current range options: 4-20 mA, 4-12 mA, or 12-20 mA. The input impedance is 170 Ω and can be directly connected to the signal output terminals of most industrial controllers and sensors. Simultaneously supporting switching between direct and reverse action modes, users can flexibly set according to on-site control logic requirements: in direct action mode, when the input current signal increases, the pneumatic output signal synchronously increases; In reverse operation mode, when the input current signal increases, the pneumatic output signal decreases in reverse, and no additional signal conversion module is required to adapt to different control scenarios.

3. Industrial grade protection design with excellent environmental adaptability

The product adopts a top mounted weatherproof shell (- T), which has excellent dust-proof and water-resistant performance. Combined with the sealed design of the explosion-proof junction box, it can operate stably in outdoor, dusty, and humid industrial sites. The internal core conversion mechanism adopts a rigid feedback bending structure and low-quality components, minimizing the impact of on-site vibration and impact on conversion accuracy; Adequate clearance is reserved between the coil and the casing of the current detection motor, effectively avoiding mechanism jamming caused by corrosion and dust particles, and solving the pain points of traditional voice coil instruments that are easily affected by the environment.

4. High precision conversion performance and excellent control stability

Relying on FOXBORO's mature signal conversion technology, this model has excellent conversion accuracy: the typical value of linearity is ± 0.5% of the range, the typical value of repeatability is ± 0.25% of the range, the typical value of hysteresis is ± 0.5% of the range, and the inactive control area is only 0.1% of the range, ensuring accurate proportional mapping between input current signals and output pneumatic signals. This high-precision feature can ensure the action accuracy of pneumatic actuators, especially suitable for process adjustment scenarios that require high control accuracy, such as temperature regulation of chemical reaction vessels, pressure control of oil and gas pipelines, etc.

5. Convenient on-site installation and controllable operation and maintenance costs

The product adopts on-site installation design and supports various installation methods such as surface installation, valve yoke installation, and nominal DN50 (2 inches) vertical pipeline installation, adapting to different on-site layout requirements. Standardized electrical and pneumatic interface design enables simple and efficient wiring and gas connection operations, without the need for specialized tools for installation and disassembly. Meanwhile, the modular internal structure facilitates the replacement and maintenance of faulty components, coupled with the configured pressure gauge and adjustable filter, further reducing the difficulty and cost of operation and maintenance.
