Rotary Vacuum Pumps are guaranteed maintenance-free for continuous usage over 3 years. Minimal clearance between the rotor and cylinder wall reduces wear and magnetic coupling in the pump eliminates the need for a sliding seal. They have minimal vibration for space-saving abilities and generate low heat by use of a forced-air cooling system. They are lightweight (23 lbs.), compact (4.9 x 15.6 x 7.1 in.) and are also available in an in-line twin rotor model, as well as Parallel Twin Rotor, Parallel Triple Rotor and Parallel Quad Rotor models. They target applications including suction transport, vacuum chuck, vacuum packing, defoaming/deaeration, and bagging and vacuum forming.
Model OACN 500 hydraulic oil coolers for mobile and industrial hydraulic systems come in 12 sizes with an aluminum plate-and-bar heat exchanger. They are compatible with fluids including hydraulic oils, lubricating oils, engine oils, and water-glycols. The variable-speed fan drive operates at to 25 kW and provides high efficiency at cooling capacities with 40° ∆T. The coolers accommodate fluid pressure up to 26 bar at maximum flow rate of 55 gpm. The self-cleaning feature reverses flow to keep heat exchanger clean.

Metal round hydraulic reservoirs are available in aluminum and steel. They are low weight with a diameter of 24 inches and lengths ranging from 15 to 51 in. Standard port sizes are 2 in. Optional rear ports are also available, along with stainless steel mounting straps. The reservoirs are especially suited for continuous applications that may generate high amounts of heat.
The ProSense SPTD25 series of pressure transmitters feature a stainless-steel, thin-film sensing element that provides fast response time in applications ranging from process control and automation to hydraulic systems, engine monitoring, and machine tools. The transmitters are resistant to high vibration, shock, and EMI/RFI, and can be used over a wide temperature range. They are available with a 0/25-in. NPT male threaded process connection, and an M12 quick-disconnect electrical connection. They have a linear 4-20 mA output and sensing ranges from 100 to 5000 psig.

A new version of the E-Series linear position sensors supports IO-Link communication protocol as outlined within the IEC 61131-9 standard, offering simple bi-directional point-to-point communication at signal-transmission rates of up to 230.4 kbps. Maximum stroke length reaches 2540 mm and deviation is minimized to less than 0.02% with a wear-free magnetorestrictive sensor mechanism. They are available with a rod-based design for in-cylinder integration, and also with aluminum housing with a guided rod that contains both the sensor element and the accompanying electronics. Key parameters can be adjusted to suit specific requirements, including reverse or forward measuring direction and offset value. Operational temperature ranges from -40°C to +75°C. They provide absolute position measurements so no recalibration is needed.
