The SVI™ II AP (Smart Valve Interface, Advanced Performance) is a state-of-the-art digital valve positioner that utilizes a 32-bit microprocessor for optimal performance. The device boasts a local interface designed to control a pneumatic actuator, which it achieves with the help of a two-wire 4-20mA control signal.
One of the standout features of the SVI™ II AP is its compatibility with the HART® protocol, which enables bi-directional communication. This means that the device can communicate seamlessly with other HART-compatible devices, opening up possibilities for advanced process control and optimization.
The SVI™ II AP is designed with supreme versatility in mind, with a universal design that makes it easy to implement in place of existing analog positioners. Whether you're working with Masoneilan or non-Masoneilan pneumatic actuators, single-acting or double-acting, the SVI™ II AP is engineered to fit seamlessly into your workflow.
The Non-Contact Position Sensing Technology utilizes sensing through the housing without requiring any mechanical moving parts to enter the main housing cavity, which ultimately prolongs the life of the technology. Additionally, this technology boasts a simple mounting procedure, further enhancing its ease of use.
The Non-Contact Position Sensing Technology is designed with ease and simplicity in mind. It features an LCD and pushbuttons that are operable in all certified hazardous environments, making it an extremely versatile tool. Commissioning of the technology is quick and accurate due to its auto stop and auto tune methods, which take the guesswork out of setup. Furthermore, this technology is designed to fit a variety of applications, whether rotary or linear, and can be used remotely or locally.
