Rugged DC Accelerometers for Steady State
and Shock Measurements

Measurement Specialties has introduced two rugged and economically priced DC accelerometers for steady state and transient measurement in harsh environments. The compact, hermetically sealed Models 3801A and 4801A incorporate gas-damped MEMS sensing elements with wide frequency response. High performance applications include flight and vehicle testing, transportation measurements, mining, ship shock and environmental testing.

Offered in ranges from ±2g to ±2000g, the accelerometers are suitable for both low-level and high-end transient shock measurements. Integral over-range stops provide shock protection to over 10,000g without affecting calibration.

Model 3801A has a mV output signal for shock pulse measurements. Model 4801A has a signal-conditioned, amplified output for low level measurements. A custom ASIC in Model 4801A provides high integral temperature compensation over a wide operating temperature range from -55°C to 125°C. The new accelerometers are easy to install, with the popular 10-32 stud mounting and 5-pin side mount connector. Both offer high capability for their size, and attractive pricing.

Measurement Specialties, Inc., designs and manufactures a wide variety of sensors and transducers to measure precise ranges of physical characteristics including pressure, force, vibration, position, humidity and temperature.

Jungheinrich’s New EFG 2 and 3 Series Trucks Offer Industry-Leading Performance and Increased Energy Efficiency with Their 4th Generation AC Technology

Jungheinrich Lift Truck Corp., a green manufacturer and supplier of eco-friendly AC-controlled electric lift trucks, has announced two new series of high performance counterbalanced trucks with capacities ranging from 2,500 to 4,000 lbs.  The EFG 213-220 and EFG 316-320 both provide state-of-the-art, 4th generation, 3-phase AC technology in their drive, hydraulic and steering systems.

The presence of this advanced technology is significant because it leads directly to higher levels of energy efficiency, as well as superior truck performance in terms of travel speeds, lift/lower speeds, acceleration and ramp handling ability.  It also means longer run times on a single battery charge.  The motors, controllers and software in the new vehicles were designed by Jungheinrich to work together smoothly and efficiently.  Under separate test conditions to measure efficiency and performance, they provide a 10% and 5% improvement, respectively, over previous EFG truck models.  No other company serving the U.S. market offers electric counterbalanced trucks with such a high level of AC technology.
Both series allow the operator to charge and change the battery via simple access from the side of the truck, and provide the convenience of several battery extraction methods, including the use of a hand pallet truck, forklift or crane.

The 2 Series offers six 3-wheel chassis variations, including two compact versions, providing more overall chassis variations than its top five competitors.  This series is extremely maneuverable in restricted spaces and works well in outdoor applications.  Its AC electric power steering not only leads to greater energy savings, but also renders load handling easier and more precise.  The 3 Series offers five 4-wheel chassis variations and is well suited to applications involving longer runs. 
Both EFG series offer advanced ergonomics and a high operator comfort level via AC electric power steering.  An innovative fingertip hydraulic control design also eliminates cumbersome hydraulic levers and offers advantages similar to the electric power steering in terms of low effort, high precision, low noise and low fatigue.  The operator sits in a “floating cab” with a comfortable, fully adjustable armrest and handrest that incorporate Jungheinrich’s standard SOLO-PILOT control (or optional MULTI-PILOT control).  By having all controls within reach, including the hydraulic controls, directional switch and horn, the operator’s hands are always on the controls.

All critical electrical components, including connectors, are protected to IP54 or greater, ensuring superior protection against ambient dust and water ingress.  The new vehicles also feature up to 1000-hour service intervals, 2 to 4 times longer than those offered by other manufacturers.  The 2 Series, in particular, has eliminated the steering pump and hoses, reducing the need for maintenance.  The fully enclosed electric disc brakes are wear-resistant and protected against the elements, assuring long brake life and limited maintenance.

Standard safety features include Curve Control for speed reduction when cornering, anti-rollback on ramps, and automatic parking brake application.  Optional load and truck control features include Access Control (preventing truck from moving until the operator is in the seat and the seatbelt is fastened), Drive Control (reducing travel speed based on lift height), and Lift Control (reducing tilt speed based on lift height).
