The PF-KBP-21Q-3 is an industrial-grade, 3-way isolated potentiometer transmitter that converts field resistance signals from 3-wire potentiometers or slidewire resistors into 4-20mA DC signals. Featuring high measurement accuracy (0.1% F.S.), versatile input ranges from 200Ω to 50KΩ, and rugged DIN-rail construction, it serves as a reliable signal conditioning link for marine and automation applications.
Field-rangeable
Accuracy 0.1% F.S.
Input/output isolation 1.6KVdc
The PF-KBP-21Q-3 serves as a critical interface in automated control and maritime Valve Remote Control Systems (VRCS), converting mechanical valve or level float telemetry into 4-20mA signals for PLCs/DCS. Featuring a 10.0 x 5.0 x 5.0 cm plug-in module for DIN-rail mounting, the device ensures easy maintenance and high vibration resistance. With extensive marine certifications (ABS, DNV, CCS, Lloyd's Register) and full galvanic isolation, it guarantees reliable operation in extreme environments with high electromagnetic interference.

Marine & Ocean Engineering
Monitors valve position feedback of hydraulic or electric valves in ballast and fuel tanks, transferring potentiometer signals from valve actuators to the vessel's monitoring system.
Thermal Power Generation
Measures the damper door openings of boiler induced and forced draft fans, converting mechanical linkage positions into 4-20mA signals for DCS inputs.
Hydropower Industry
Monitors turbine governor guide vane openings and inlet butterfly valve strokes, assisting in regulating water flow entering the hydro turbine.
Chemical & Paper Industry
Tracks the precise stem displacement of control valves on highly corrosive media pipelines, enabling high-precision closed-loop flow and pressure control.
Iron & Steel Industry
Tracks the physical stroke and limit positions of heavy machinery drive components in blast furnace charging systems and converter tilting devices.
Rail Transit
Assists in monitoring the stroke status of large hydraulic telescopic rods in heavy operable bridges and railway switch machines.
When wiring, strictly follow the pin definitions, ensure the correct polarity of the DC 24V power supply, and verify that the input is connected to a 3-wire potentiometer within the 200Ω to 50KΩ range. The transmitter should be snapped onto a 35mm DIN rail with adequate ventilation maintained inside the control cabinet to prevent heat buildup. During on-site commissioning or valve calibration, use a multimeter to fine-tune the side ZERO and SPAN potentiometers, avoiding excessive force to prevent damage to internal components.
It is a programmable potentiometer transmitter, specifically designed to receive resistance change signals from field valves or equipment and convert them into isolated standard electrical signals.
How to properly use transmitter products like PF-KBP-21Q-3?
Insert it into its dedicated plug-in socket, mount it inside the control cabinet via a 35mm DIN rail, and correctly wire the potentiometer, power supply, and PLC analog module according to the pin definitions.
Why does the marine industry widely select the PF-KBP-21Q-3 transmitter?
Because it has passed certificates from global major marine classification societies such as ABS, CCS, DNV, LR, and BV, demonstrating excellent stability in high-humidity, vibration, and salt mist marine environments.
Is the terminal barrier of PF-KBP-21Q-3 safe if the field environment is harsh?
Its plug-in socket is equipped with barrier terminals, and the body uses flame-retardant engineering plastics, providing sound physical and electrical protection.
If the PF-KBP-21Q-3 is damaged, can the module be replaced alone or must it be replaced along with the base?
The module can be replaced individually. Thanks to its plug-and-play split design, you only need to unplug the old module and insert the new one without disconnecting the wires on the base.
