Sensing Methodologies in Pinch Valves

This white paper examines various types of state sensors and their functional use in pinch valves for advanced system development. Many systems today, including medical and biopharmaceutical applications, require precise control and monitoring of a variety of fluids during operation. Systems can employ several methods to control fluid. Solenoid and pneumatic pinch valves, used in conjunction with flexible tubing, offer a simple approach to non-wetted fluid control. At the most fundamental level, various types of sensors can be incorporated into pinch valves to provide feedback showing the physical, open or closed, state of the valve. This paper covers both the basics of state sensing as well as advanced applications to detect the presence of tubing.

Shaping the Future of Service Robotics

Robots emerged in the early 1960s as a way to automate the monotonous and dangerous tasks in factories around the world. As time passed and new technologies emerged, these robots have taken a place outside of the industrial market and alongside humans in manufacturing and non-manufacturing applications alike.

How to Select a DC Motor: Coreless and Iron Core Brushed DC Motors

DC motors possess linear relationships that allow for very predictable operation. Motion control manufacturers and designers depend greatly on the premise that these linear relationships will hold true, since the laws of physics do not change. However, despite their simplicity, selecting a DC motor for an application can still be a daunting task. There are many other variables to take into account including dimensions, load, duty cycle, etc. This white paper provides an overview on Coreless / Brushed DC motors, and what to consider before committing.

Multiturn Kit Encoders Without Batteries or Gears: A Cost-Efficient Approach for Rotary Position Measurement in Servomotors and Rotating Equipment

POSITAL is introducing a new set of component-level products that are designed to be built into servomotors or other types of equipment when real-time measurement of rotary position (angular displacement) or rotational speed is required. Based on POSITAL’s well-proven magnetic rotary encoder technology, these new products provide manufacturers with a flexible and cost-effective way of incorporating rugged and precise rotation measurement capabilities directly into their devices.

How To Substantially Reduce Encoder Cost While Gaining Functionality With Multi-Turn Rotary Position Sensors

Many applications require rotation counters that can measure angles greater than 360º. However the low-cost 10-turn potentiometers most design engineers are familiar with can’t always meet user requirements for resolution and reliability. As an alternative, optical absolute encoders are too expensive for many applications. These solutions require a continuous power supply or they will lose count when power is restored. Also, geared technology/rotation counters are subject to significant wear.

Pedal Position Sensing in Heavy-Duty Vehicles

Pedal position detection is nothing new when it comes to operation of heavy duty equipment. However, the age old system operation of mechanical linkages between the pedal and the engine just might be coming to an end. New sensor technology is now enabling non-contact, drive-by-wire that can reduce total system cost while standing up to the harsh environments of off highway equipment.
