Principle of Operation
The T1500 operates on a force balance principle. A coil suspended in a magnetic field generates movement when an electrical current flows through it. This movement creates back pressure in a nozzle, which acts as a pilot pressure for an integral booster relay. The output pressure increases proportionally with the input signal, allowing for precise control.
Installation Guidelines
Mounting Options
The T1500 can be mounted in various orientations, including vertical, panel, pipe, and DIN rail configurations. For optimal performance, it should be installed in a vibration-free environment. Calibration is recommended after installation to ensure accuracy.
