Product Description

Product Description

Gulde 3800SA

The intelligent locator is expertly engineered to be easy to use, compact in size, and easy to install. It efficiently converts a 4-20 mA input signal into a precise pneumatic output signal to drive the control valve actuator with exceptional accuracy. Parameter settings are intuitively made through buttons and an LCD screen on the interface, ensuring user-friendly operation. The LCD screen is strategically located inside the protective cover, thus it is not affected by the environment, ensuring durability in various conditions. Gulde 3800SA supports a convenient Chinese interface for accessibility.

Gulde 3800SA A two-stage positioner design is superbly adopted. The preamplifier provides a high static gain to respond to even the most minor changes swiftly and accurately. in the input signal. The pneumatic amplifier delivers sufficient compressed air to the actuator, allowing the equipment to achieve optimal dynamic performancewith minimal steady-stateair consumption.

 

Linkage‐Less Non‐Contact Position

Feedback - This state-of-the-art, high-performance linkage-less

feedback system eliminates the need for

physical contact between the valve stem and the

3800SA, ensuring parts remain unworn and

maximizing the cycle life of the system.

 

Built to Survive - The 3800SA is engineered to withstand

harsh conditions with fully encapsulated electronics that resist

vibration, temperature fluctuations, and corrosive

environments. A weather‐tight wiring terminal box

securely isolates field wiring connections, maintaining the

integrity of the instrument's other components.

 

Actuator Overpressure Prevention

Gulde 3800SA The smart locator can also be installed on other actuators that comply with the installation standards

of IEC 60534-6-1, IEC 60534-6-2, VDI/VDE 3845 and NAMUR.

Incoming signal

Analog input signal: 4-20 mA DC, standard; minimum voltage for division: the available voltage at the

instrument terminal must be 8.5 V (for analog control) or 9.0 V (for HART® communication), maximum

voltage: 30 V DC voltage Minimum control current: 4.0 mA (below 3.5 mA may cause the microprocessor to restart) Overcurrent protection: The input circuit limits the current to avoid internal damage. Reverse polarity protection: The reverse loop current will not cause instrument damage.
