Several technologies exist to provide position feedback or data of a cylinder’s position. Linear position sensors convert the position into a proportional analog or digital signal. LVITs—Linear Variable Inductive Transducers—are contactless position sensing devices, with sensing ranges up to 30 inches or more. Most designs feature an inductive probe surrounded by a conductive tube. This is […]
LVITs for cylinder and actuator feedback
Alliance Sensors Group is pleased to announce the continued success and expansion of the ME, MR, MHP, and now the SS-7 Series Linear Position Sensors used to measure the ram position of hydraulic and pneumatic cylinders in industrial, mobile, or subsea applications. With no magnet required, the installation and cost of ownership is dramatically reduced […]
Monitor pressure the easy way
The Ashcroft DG25 digital pressure gauge provides a 5 full digit LCD in ranges up to 25,000 psi. Available in accuracies of 0.5% and 0.25% FS, this leading-edge design boasts a minimum battery life of 2000 hours. Standard features include an IP67 enclosure, selectable units of measure, a 20 segment bar graph indicator, min-max, tare […]
Watertight or explosion-proof stainless steel pressure switch
A harsh operating environment is no match for Ashcroft’s A-Series 316L stainless steel pressure switch. Available in both explosion proof and watertight configurations, it is offered with a variety of connections and can control pressures up to 15,000 psi. This durable, compact switch is a suitable choice for a wide variety of industrial and OEM […]
New diaphragm-operated pressure switches for tough environments
For operation in tough environments, Sigma-Netics Inc. has added two diaphragm-operated options to its portfolio of ruggedized pressure switches. Similar products were only previously available in piston-based operations. The new 745 and 785 series of pressure switches are designed for low-pressure, high-sensitivity applications, including off-road or industrial OEM equipment, train braking systems, compactors, compressors and […]
Parker’s Intellinder absolute position sensor suitable for industrial, mobile applications
Parker Hannifin has introduced a new integrated absolute position sensor that can provide improved application productivity while offering low installation and maintenance costs. Intellinder equipped cylinders provide a rugged, damage resistant solution for use in OEM equipment that requires precise linear feedback of the cylinder position. Intellinder equipped Parker cylinders are able to support a […]
J1939 sensors measure hydraulic flow, temperature, pressure
Webtec has introduced a series of new SAE J1939 CAN hydraulic sensors for OEM mobile and industrial applications where customers require real-time monitoring of hydraulic flow, pressure and temperature around the clock. Designed for closed loop control on high-pressure hydraulic systems, the sensors help users predict imminent hydraulic failure or they can be used to […]
Dynamic Positilt PTK29 inclination sensor offers high accuracy and signal transmission with no delay
Inclination measurement in mobile machines is exposed to motion, shock and vibration. Under these influences normal inclinometers will give incorrect values affecting sensor accuracy. ASM Sensors introduces the Positilt PTK29 inclination sensor that compensates dynamic influences to give correct values even when in motion. The sensor measures inclination between ±180° with 1 axis or ±60° […]
Three key priorities for successful agricultural hydraulic design
Agricultural hydraulic design systems must be energy efficient, easy to operate and maintain, and of course reliable. Contributed by Carl Dyke, CD Industrial Group, Inc. Designers of hydraulic systems for agricultural machines face some difficult challenges. This is especially true for high horsepower tractors with not only steering and brake functions, but where a great […]
Rotary encoders keep firm grasp on angles and paths, even under tough conditions
One of the more interesting products I saw at the Hannover Messe in Germany last week were these new rotary encoders from the people at SIKO. Safety guidelines for mobile machines have been top of mind, even before the introduction of EN ISO 13849. With the release of EN ISO 13849, many things have changed […]
