Application Checklist

Bimba Position Feedback Cylinders

This section contains Bimba’s Position Feedback Products. These products are ideal

for applications that require increased flexibility and adaptability. They are perfect for

automated assembly processes that require quick changeovers or for mass customized

product assembly.

The Position Feedback Cylinder (Model PFC) is a linear pneumatic actuator that contains

an internal LRT (Linear Resistive Transducer). The PFC can be used for measuring and

gauging, positioning, and “on-the-fly” applications. It is available with or without a rod

lock. Combine the PFC with the Bimba Pneumatic Control System Model PCS, Digi-

tal Panel Meter Model DPM, or the Electronic Controller described below to maximize

performance.

The Position Feedback Cylinders Non-Contact (Model PFCN) is similar to the original

Model PFC, except it employs a magnetostrictive sensor instead of a LRT. The new

technology is ideal for applications that involve dirty or moist environments, rapid oscil-

lation over a small increment of stroke, and vibration. In addition, it is relatively immune

to air line contamination. It is calibrated to produce exactly 0 volts fully retracted and 10

volts fully extended. Like our original PFC, it is available with or without a rod lock.

The Pneu-Turn rotary actuator with position feedback (Model PTF) is a rotary rack and

pinion actuator that has a rotary potentiometric feedback transducer attached to the

output shaft. The PTF can be combined with Bimba’s Pneumatic Control System Model

PCS described below for closed loop rotary positioning.

The Pneumatic Control System (PCS) is a closed loop pneumatic motion control system

that controls the position of the PFC rod or the PTF shaft. The system includes the con-

trol electronics and valves necessary to accurately control any Bimba position feedback

actuator.

The Digital Panel Meter (Model DPM) is a digital panel meter that has a 16 bit A/D

converter and built in microprocessor. When combined with the PFC, the repeatability

is 0.001 inch per inch of stroke. The DPM is great for accurate measuring and gauging

applications. It is easily calibrated to indicate actual displacement and includes multiple

programmable set point outputs. Recommended applications include Go/No Go in-pro-

cess quality control verification, part identification, and dimensional verification.

The Electronic Controllers can be used for applications that require accuracy larger than

+/- 0.030". It has 10 VDC transducer excitation and fast responding scalable analog

output capability. It is good for applications that use controllers that do not have the

required PFC input impedance of 1 Mohm.
