Sensors & Gauges

Knowing which style of pressure gauge is right for your fluid power system is critical in ensuring consistent, efficient operation. Contributed by Carl Dyke, LunchBox Sessions Pressure gauges are unsung heroes in many hydraulic systems. They are neither directing flow nor controlling pressure. If the pressure gauge is damaged or goes missing, the machine may…

The new high-accuracy inclination sensor positilt PTM27 from ASM Sensors comes in an ultra-compact housing and is suitable for applications where high robustness and accuracy are required. It can also replace rotary angle sensors advantageously. The new positilt PTM27 sensor measures inclination in the range of ±180° with one axis and in the range of […]

Holmer Maschinenbau GmbH, a German-based agricultural company, developed the first self-propelled six-row sugar-beet harvester in 1974. Since that time, the Holmer machines have been in successful operation by customers in over 40 countries world-wide. On its sugar beet harvesters, it requires a precise collection of actual values directly at the place of consumption (propulsion, toppers, […]

Linear Variable Inductance Transducers (LVITs) from Alliance Sensors Group convert the linear displacement of an object into a proportional electrical signal output of 0-10 V or 4-20 mA (depending on model). LVITs are contactless devices designed for dimension or position measuring applications where the sensing element cannot be attached to the object being measured. LVITs […]

Rugged digtial pressure gauge GE2514A from BVA Hydraulics is extremely accurate and offers a thick rubber shell to protect against the toughest elements. More precise readings will ensure you get the job done right the first time. It features a 5-digit display that allows readings over 10,000 psi, a zero reset feature. Connection is via a 1/4…

AW-Lake continues to maintain their standard lead times on flow meter orders to serve the needs of manufacturers, especially those experiencing a disruption in their supply chain. A survey conducted by the National Association of Manufacturers reported that 36% of manufacturers are experiencing supply chain disruptions or receiving parts late or not at all.  AW-Lake can…

Any book or lesson in fluid power worth its weight in gold will discuss the importance of electrical and electronic control of hydraulics. In fact, over the past few decades, most advancement in hydraulics has been in how it’s controlled rather than improvements in the foundational components such as valves, pumps and actuators. Understanding electrical…

Liquid-filled gauges are used to damp vibrations and pulsations and minimize their effect on the gauge dial pointer. They are used primarily in dynamic and rugged applications where sudden shocks or pressure spikes might occur. They help to ensure the gauge maintains accurate readings for its rated lifecycle. This longer lifecycle means longer-term cost savings,…

For use with air and compatible non-combustible gases, ProSense® DGA differential pressure gauges are used to measure and display difference in air pressure between two reference points in inches of water. Applications include air/gas flow indication, filter monitoring, cabinet purging, room positive or negative pressure status and more. These high-quality gauges feature an industrial grade…

The new Ashcroft 1209 pressure gauge provides maximum safety in harsh environments. A 316L stainless-steel solid front case and ring along with a pressure-relief back ensure that the process fluid will be directed away from the operator in the event of an internal failure. Optional liquid fill or the patented PLUS! Performance option dampens shock,…

By Martin Cuthbert, Managing Director, Webtec Ltd What is flow? Flow is the measurement of the volume of a liquid that passes a fixed point in a unit of time. For most hydraulic applications, flow is measured in liters per minute (lpm), U.S. gallons per minute (US gpm), or, occasionally, U.K. gallons per minutes (UK…

Transducer is a mystical word. Saying it emotes feelings of the word transmogrify, which itself describes the magical transformation of an object or person. The word transducer was certainly a mystery to me when I was a fluid power neophyte. I knew a transducer was some sort of electrical device, but I didn’t know how […]

Every three years, the fluid power world comes together at IFPE. This year’s event will be at the Las Vegas Convention Center from March 7-11, and it will offer designers the opportunity to see what’s new with pressure transducer technology. Here you can learn how they are constructed and used on mobile machinery. Below, you […]

Mobile Hydraulic Tips

Mobile hydraulic measuring equipment requirements correlate with ongoing improvements in machine technology (providing for example, a greater number of functions, shorter production cycles, and higher process precision) and with higher expectations with regards to inspection, testing, fault finding and documentation (such as documentation for final machine acceptance). Furthermore, measurements now need to include events and […]
