In the realm of industrial automation and process control, the Samson 4763 Electropneumatic Positioner stands out as a crucial component for achieving precise and reliable control of pneumatic actuators and valves. This device plays a vital role in various industries, including chemical, petrochemical, power generation, and water treatment, by ensuring accurate positioning of valves to regulate the flow, pressure, and level of fluids.
The Samson 4763 is designed to accept a wide range of input signals. It can handle standard analog signals such as 4 - 20 mA, which is commonly used in industrial control systems to represent a proportional value of a process variable. This input signal is then converted into a corresponding pneumatic output signal to drive the connected pneumatic actuator. The output signal is typically in the range of 0.2 - 1 bar or 3 - 15 psi, which is suitable for most pneumatic actuators in the market.
One of the key features of the Samson 4763 is its high accuracy and repeatability. The positioner is capable of achieving an accuracy of ± 0.5% of the full - scale travel, which means that it can precisely position the valve to the desired opening or closing position. This high level of accuracy ensures that the process variables are maintained within the required limits, leading to better process control and product quality. The repeatability of the positioner is also excellent, with a value of ± 0.2% of the full - scale travel. This means that the positioner will consistently return the valve to the same position under the same input conditions, providing reliable and stable operation over time.
Features
The Samson 4763 can operate with a supply pressure ranging from 1.4 - 7 bar or 20 - 100 psi. This wide range of supply pressure allows the positioner to be used in different industrial applications with varying pressure requirements. The flow capacity of the positioner is also an important factor, as it determines how quickly the positioner can move the valve to the desired position. The Samson 4763 has a relatively high flow capacity, which enables fast response times and efficient valve operation.
In addition to its analog input and output signals, the Samson 4763 supports several digital communication protocols. It is compatible with HART (Highway Addressable Remote Transducer) protocol, which allows for two - way communication between the positioner and the control system. Through HART communication, the control system can access diagnostic information, perform configuration changes, and monitor the status of the positioner in real - time. The positioner also supports PROFIBUS PA and FOUNDATION Fieldbus protocols, which are widely used in industrial automation networks for seamless integration with other field devices.

Product Overview
The Samson 4763 is housed in a robust and durable enclosure. The housing is made of high - quality materials that provide protection against environmental factors such as dust, water, and corrosion. It is designed to meet the IP65 protection rating, which means that it is completely protected against dust ingress and can withstand low - pressure water jets from any direction. This makes the positioner suitable for use in harsh industrial environments, including outdoor installations.The positioner offers flexible mounting options. It can be mounted directly on the actuator using a variety of mounting kits, which are available for different types of actuators. This direct mounting ensures a compact and integrated installation, reducing the overall footprint of the valve - actuator - positioner assembly. Additionally, the positioner can also be mounted remotely from the actuator if required, providing greater flexibility in system design.
Inside the housing, the Samson 4763 consists of several key components. The microprocessor - based control unit is the heart of the positioner, which processes the input signals, performs calculations, and controls the output pneumatic signals. The position sensor, which can be a potentiometer or a non - contact sensor, measures the actual position of the valve and provides feedback to the control unit. The pneumatic amplifier is responsible for amplifying the control signals to drive the actuator, and the solenoid valves are used for quick venting and filling of the actuator chambers.
