Gulde 3800SAIntelligent Locator

- Gulde 3800SAThe intelligent locator is simple to use, compact in size, and easy to install. It will4-20 mAThe input signal is converted into a pneumatic output signal to drive the control valve actuator. Parameter settings are made through buttons and LCD screens(LCD)Interface to proceed. The LCD screen is located inside the protective cover, so it is not affected by the environment.Gulde3800SASupport Chinese interface.
- Gulde 3800SAAdopting a two-stage locator design. The preamplifier provides a high static gain to respond to small changes in the input signal. The pneumatic amplifier delivers sufficient compressed air to the actuator, enabling the equipment to achieve optimal dynamic performance with minimal steady-state air consumption.
- The high-performance non connecting rod valve position feedback system avoids actual contact between the valve stem and the positioner. This way, there will be no wear on the parts, thus achieving the maximum cycle life. Due to the absence of connecting rods and pins, the number of installation parts and the complexity of installation are reduced, and the feedback components are retained on the actuator push rod, greatly simplifying the replacement and maintenance of the locator.
