FIAMA PR20 series potentiometers

1、 Brand Introduction

Fiama was founded in 1913 as a mechanical workshop. After World War II, it developed agricultural machinery manufacturing instruments and established itself as an automation component manufacturer.

Fiama designs, manufactures, and markets mechanical, electrical, and electromechanical measuring and control instruments, such as:
-Position indicator
-Servo drive
-Encoder, potential sensor, magnetic measurement system
-Liquid level control (Atex)
-Monitor
-Angular gears and transmission

These products are mainly used for manufacturing machinery in the food, packaging, wood, glass, ceramics, marble, sheet metal, and milling industries.

Rich experience, special attention to materials, and qualified personnel ensure the high quality of the product. The company has obtained UNI EN ISO 9001 certification since 2001.

Research and manufacturing are conducted internally, allowing for control over product manufacturing and providing customized applications.

The R&D investment in collaboration with the University of Parma enables production to adapt to continuous technological innovation and respond to market demand.

2、 Product Introduction

PR10、PR20isPotential sensors can rotate and move in resistance changes: they are made of precision rotary potentiometers and receive motion from the drive shaft through a suitable transmission system.

The potentiometer can provide 1, 3, 5, or 10 revolutions, and there is a transmission ratio between the drive shaft and the potentiometer.The reducer is equipped with a clutch to protect the potentiometer.
To use these sensors, it is necessary to know the number of revolutions required for the drive shaft to produce the total stroke of the machine: the number of revolutions is determined by the gear ratio (gear ratio or reduction ratio) of the gearbox and the potentiometer rotation.
Version:
• PR20- Hollow shaft with Ø 20mm hole
•PR10-Featuring a Ø 6 x 14mm axis.
• PR20-I、-VEquipped with built-in analog interface and 24Vdc power supply:PR20-IOutput 4-20mAPR20-VOutput 0-10 Vdc.

The combination with displays (V3P, V4P, P3X) makes this device an economical, simple, and effective system for measuring displacement of machine tools, automation, marble, glass processing machinery, etc., with an accuracy of no more than ± 0.1 millimeters.
Shockproof, self extinguishing shell, anti solvent, anti gasoline, anti oil, anti grease.
