ControlAir Inc. has announced its P200 and P290 pneumatic-to-current P/I transducers. These transmitters are designed to convert standard 3-15, 3-27 or 6-30 psig air pressures into a two wire 4-20 or 10-50 mA signal with a total accuracy up to +/- 0.10%.
Positioning sensors
Proximity sensors are versatile, reliable
Festo proximity sensors SMT-/SME-10M are applicable to a wide range of drive units and offer a new dimension of reliability and cost effectiveness. The long cylinder-style sensors detect the position of magnets fitted to pneumatic drives.
Replacing linear pots with non-contact technology
Typical resistive linear potentiometers are especially vulnerable to performance degradation caused by wear to the resistive element. Because the measurement principle relies on mechanical contact between the resistive element and conductive wiper, mechanical wear can lead to erratic output signals and, ultimately, unreliable process control.
Pressure Transducer RoHS and CE Compliant
Setra’s model 204R Pressure Transducer is intended for accurate pressure measurements of a gas or liquid. Its high level output signal and excellent stability, combined with fast dynamic response, make this unit a good choice for industrial, laboratory and aerospace applications. The high level of accuracy is attained by combining Setra’s electronic circuitry with its […]
Non-Contact Linear Position Sensor
The TMI Series of non-contact linear position sensors from Novotechnik offers rod-style position sensors designed for integration into hydraulic and pneumatic cylinders. Implementing the Novostrictive touchless magnetostrictive measuring process, these sensors measure positions using a passive position marker that can be moved as a free-floating element. Additionally, the temperature coefficient of the transducer is extremely […]
Position Feedback Cylinder
The TD (transducer) Option position feedback sensor offers an internal Linear Resistive Transducer (LRT) for extremely accurate piston position sensing. It’s designed for applications where magnetic Reed and Hall effect switches are unacceptable. The TD Option provides a solution for applications where variations in cylinder stroke and speed are required. Available with bore sizes ranging […]
Valve Positioners For Pneumatic Actuators
Spirax Sarco’s EP5 and PP5 control valve positioners operate on the balanced forced principle providing a tested solution for accurate control valve positioning. Both types are simple to commission and maintain with a low air consumption and 0,2 to 1,0 bar and 4-20 mA input signal options. The positioners are used with linear pneumatic actuators; […]
Dual-sensor, Split-connector Cuts Cylinder Costs
Three areas where you can look to cut costs on pneumatic cylinder applications include installation time, cables, and the sensors used for detecting the piston’s position. For example, first consider the sensor in a standard cylinder. Most standard cylinders use proximity switches, either internal or external to the aluminum housing that detect special targets or […]
Enfield Technologies Makes Proportional Pneumatic Control More Affordable
Thanks to some innovative engineering, Enfield Technologies has reached an important goal – making a complete proportional pneumatic control system much more affordable. A basic positioning system includes a proportional valve and control electronics manufactured by Enfield Technologies paired with a pneumatic actuator and a position sensor provided by a variety of highly regarded partner […]
DUAL SENSOR FOR C-GROOVE CYLINDERS
BIM-UNR Dual Sensor (High-Res) TURCK’s BIM-UNR line of compact magnetic cylinder position sensors now includes a dual sensor designed for detecting short and long stroke C-groove cylinders. BIM-UNR dual sensors provide a distinct advantage by combining two sensors through one cable connection to speed installation, as well as lessen wire costs and connection points. This […]
