Product Description

Product Description

Gulde 3800SA

The state-of-the-art intelligent locator is remarkably easy to use, with its sleek and compact in design, and effortlessly easy to install. It seamlessly converts a standard 4-20 mA input signal into a precisely tuned pneumatic output signal to efficiently drive the controlvalve actuator. Parameter settingsare conveniently made through intuitive buttons and a user-friendly LCD screen on theinterface. The LCD screen, conveniently located inside the sturdy protective cover, ensures it is completely unaffected by the harsh environments. Gulde 3800SA further supports a comprehensive Chinese user interface.Gulde 3800SA features a cutting-edge two-stage positioner design. The integrated preamplifier offers

exceptionally high static gain, allowing it to adeptlyrespond to even slight changes, thereby ensuring optimal performance. The Gulde 3800SA represents the pinnacle of advanced technology, ready to address the needs of modern industrial applications.ges in the input signal. The pneumatic amplifier delivers sufficient compressed air to the actuator, allowing the equipment to achieve optimal dynamic performance with minimal steady-state air 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 stan

dards 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) maxi

mum 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 damag
