The SVI II AP (Smart Valve Interface, Advanced Performance) is a highly efficient digital valve positioner designed with a 32-bit microprocessor. Its local interface enables control of a pneumatic actuator that uses a two-wire 4-20mA control signal. With the instrument's bi-directional communication capabilities enabled via the HART protocol, it offers superior operational performance.
One of the primary advantages of the SVI II AP is its universal design. It makes retrofitting easy and seamless, allowing for replacement of existing analog positioners on single-acting or double-acting Masoneilan or non-Masoneilan pneumatic actuators. This feature ensures that the instrument is suitable for a range of different scenarios and configurations.
With its advanced capabilities, the SVI II AP is recommended for fluid control applications requiring high accuracy, reliability, and intelligent control. The device is also easy to use and offers significant improvements in efficiency and productivity, making it ideal for use in various industrial settings.
The technology used in this equipment is Non-Contact Position Sensing Technology, which allows the sensor to sense through the housing. This has several benefits, such as prolonging the life of the equipment because no mechanical moving parts enter the main housing cavity. Additionally, the mounting procedure is simple, making it easy to install.
This equipment is easy, simple, and accurate to use. It features an LCD and push buttons that are operable in all certified hazardous environments, ensuring safety during use. Moreover, commissioning with auto stops and auto tune methods is quick and accurate, making this equipment reliable and efficient. Furthermore, this equipment has a versatile design that fits many applications, allowing for rotary or linear functionality and remote or local operation.
