The Ashcroft Model K dual sensor thermometer combines two independent temperature sensing devices into a single instrument. For local indication, a silicone-dampened mechanical ANSI/IEC/EN classified bimetal system drives the pointer over an 80-, 100-, 130-, or 150-mm diameter dial. The choice of a stem from 90mm to 2000 mm also contains a type K thermocouple…

Condition monitoring symbols are the lesser-known and lesser-used of the hydraulic library. It’s not that the components or the symbols representing them do not serve a useful purpose. It’s that the order of operations for designing and drawing a hydraulic system are actuators, pump(s), control valves and then conditioning components. Monitoring symbols represent the nice…

Balluff’s newest family of 5 mm inductive sensors are designed to take the heat. Unique to the market, these miniature sensors are approved to operate at ambient temperatures of up to 135 °C. Along with the high temperature resistance, both the sensor and the connector provide IP67 rated protection thanks to a new crimping technique […]

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 […]

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,…
