PFA3000 12000

Wire linear potentiometric transducers

The PFA3000, PFA4000, PFA5000, PFA6000, PFA8000, PFA10000, PFA12000 are wire potentiometric position transducers that turn a linear motion into a resistance variation. They are made of a precision rotating potentiometer operated by a winding or unwinding stainless steel wire. Special features of these transducers are their low cost and easy assembling.
Available analogue outputs in voltage and current.
Linked together to a display or an electronic positioner (for example V3P, V4P, VE6P, P3X) it supplies a simple and effective system to measure linear motions on cranes, rolling shutters, cylindrical-, hydraulic-, pneumatic stroke, automatic-, wood-, marble-, glassworking machinery, etc.
These transducers are carried out in case in oxidized aluminium.

The instruments of the V_P series are multifunction microprocessor display units with input from potentiometric transducer that are particularly indicated for the measurement of linear and angular dimensions. 
• V3P: the measured dimension may be compared with 3 intervention thresholds that may be set for the enabling of as many relays, the status of which is displayed through a led.
VersionsV3P- displayed, V3P-3 displayed with 3 intervention ON/OFF. 
• V4P: the measured value can be compared with 2 or 3 alarms settable for enabling many relays whose status is displayed by LEDs. Two analog outputs, a voltage 0-10V or -10 to +10 V, the other 4 ÷ 20mA 12-bit resolution, and its possible to configure the instrument and check its status via serial interface RS485 with MODBUS RTU protocol.

The P_X positioning units serie are programmable microprocessor single-axis positioner with relay or analogue outputs.
• P3X: processes signals provided by potentiometric position transducers linear or rotary. The 16-key keyboard with 6 operation indicators make it simple and easy to use and the setup of the positioner.
