Carbon graphite bushings
Metallized Carbon Corp. has released Metcar carbon graphite bushings for use in gear pumps that pump aviation fuel for aircraft engines.
The carbon graphite bushings support the drive and idler gear shafts. They are ideal for this application because they can use aviation fuel as the bushing lubricant.
The carbon graphite bushings are also self-lubricating, can run dry for short periods of time and are dimensionally stable. This permits the close bushing-to-shaft running clearances required in gear pump applications. They have a relatively low elastic modulus, meaning that the running clearance between the shafts and the bushings will remain the same throughout the operating temperature range of the pump.
Rohrback Cosasco’s Ultracorr 2, a corrosion and erosion monitoring system, provides direct wall thickness and temperature measurement on a pipe or vessel. The Ultracorr 2 ultrasonic reader is ideal for offshore, refinery or pipeline applications where direct corrosion and erosion of complex pipe geometry is desired or where monitoring locations are in areas where access may be limited.
After initial installation, access to the corrosion monitoring point is no longer required. The sensor will be permanently fixed to the outer pipe wall, and the connector can be run to a remote location for taking thickness and temperature readings using the portable data logger unit.
These readings can be downloaded to a PC using software for storage and trend analysis.

Electronic level system
The Talyvel 6, an electronic level system, from Taylor Hobson provides measurement for industrial, civil, marine and optical engineering applications. It offers reading of angle of tilt and measurements relative to gravity, and it is simple to calibrate and operate with a fast measurement response time. It also checks the flatness of granite and cast-iron tables. It is used for measuring straightness, flatness or absolute level, and can function as a comparator to detect departures from a preset altitude that may not necessarily be level.
The Talyvel 6 level unit can be positioned remotely for difficult-to-see or confined spaces. It incorporates a pendulum-type transducer that provides measurement stability. The Talyvel 6’s built-in electronics allows the unit to interface directly to dedicated PC software with button-driven touchscreen operation. A large on-screen display shows the live measurement figures. Sequential measurements are tabulated on screen and can be saved to a file.
Mahr Federal’s MarCal 16 EWRi digital calipers send data to a small i-stick
receiver, and the MarCom software measures and
transmits it directly into an Microsoft Excel spreadsheet. The
transmitter is built into the digital indicator. Each MarConnect
i-stick wireless receiver supports up to eight measuring instruments with a range of up to 12 m.
The MarCal 16 EWRi digital calipers are easy to read with a large digital display. They also feature lapped guideways and a reference system that retains the zero position setting. Wireless data transmitters are built into MarCal 16 EWRi digital calipers, so no interface boxes or additional batteries are required.
Printed cable reel
Cerrowire’s True Sequential Footage, a sequentially printed cable reel that provides accurate wire length with each cut, prevents the need to carry excess cable inventory, providing precision length and accurate footage.
The True Sequential range is guaranteed by Cerrowire to be accurate to ±0.5% on reels 1,000 ft. and longer for sizes 1 AWG and larger. Up to 8% of lost wire is saved when the precision footage marking system is used.
Rotary position sensor
Turck has introduced the QR24 rotary position sensor. The QR24 provides contactless position detection in industrial applications ranging from solar energy plants and harvesters to crane and automated guided vehicles.
The sensors incorporate manufactured printed emitter and receiver coil systems. The emitter coils are activated with a high frequency alternating-current field and produce an inductive resistance inductive capacitance circuit with the positioning element. The element is inductively coupled with the receiver coils, which are arranged so different voltages are induced in the coils, depending on the position of the actuator. The voltages serve as a measure for the sensor signal.
The QR24’s multi-coil system provides high-resolution features and a double resonator system, providing increased distance capability and high-end signal processing with multi-core microprocessor. The QR24 sensor is fully potted and sealed in IP69K/IP67-rated housing to protect against moisture and dust.
