Display with potentiometric input

The instruments of the V4_ series are multifunction microprocessor display units with input from potentiometric transducer that are particularly indicated for the measurement of linear and angular dimensions, o display force, pressure, weight values for process variables, analogue outputs of inverters and actuators, etc.  
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.

The PF are wire potentiometric position transducers that turn a linear motion into a resistance variation.
Special features of the PF transducers are their low cost and easy assembling.

They are made of a precision rotating potentiometer operated by a winding or unwinding stainless steel wire.
 for more complete information, see sec. "Linear wire transducers, absolute and incremental" in the drop-down menu on the left.

The PR10, PR20 are potentiometric transducers that turn a rotative motion in a resistance variation: they are made of a precision rotating potentiometerthat, through a suitable transmission system, receives the motion from a drive shaft.
