Novel Variable Capacitance Accelerometer Featuring Onboard, Microprocessor-Based Temperature Compensation


Endevco Corporation has announced introduction of the Endevco model 7290D variable capacitance accelerometer with onboard, microprocessor-based temperature compensation. It is designed to provide very high thermal stability and global accuracy required for measurement of relatively low-level accelerations in laboratory test and measurement, automotive and aerospace applications including both military and commercial flight testing.


With its onboard, microprocessor-based temperature compensation, the model 7290D delivers 2.5% total dynamic accuracy over the entire military spec temperature range of -55 °C to +125 °C. Total dynamic accuracy is defined as the root of the sum of the squares of thermal sensitivity shift, non-linearity and hysteresis, and transverse sensitivity ...

High Performance KX Series Magnetic Encoders Offer Affordable Solutions


Admotec Inc. has introduced the new RoHS compliant KX Magnetic Encoders to provide high performance in harsh or difficult environments where traditional encoders don’t work or don’t last. Available in standard and custom configurations, these rotary magnetic encoders offer original equipment manufacturers affordable solutions in any quantity—from prototype to high volume production.


Because the KX encoders are magnetic rather than optical, they are immune to dust, dirt, oil, water and other contaminants found in harsh environments. Their high performance characteristics include resolution up to 45,000 cycles per revolution (CPR), maximum speed up to 100,000 RPM, and accuracy of ≤ 4 arc minutes. These new encoders feature rugged construction that tolerates high vibration and shock and a non-contact design that eliminates wear and aging ...

Universal Signal Conditioning for Optical and Magnetic and Angle Sensors


iC-MQ's universal signal conditioning facility is suitable for optical and magnetic linear and angle sensors. For the very first time, outstanding diagnostic features are now available. Operational errors, such as signal loss or clipping, exceeding a preset operating temperature range or RPM speed and – as a totally new feature – a line count error of the scale or disc pattern, are detected, signaled to the PLC and transferred to a non-volatile diagnostic memory.


iC-MQ provides up to 400 angle steps for sine interpolation; to improve angle accuracy, this basic function is supplemented by a finely adjustable signal conditioning circuitry, a signal path multiplexer (which keeps pin functions variable) and fault-tolerant RS422 line drivers. Device installation with incorrectly connected wires is tolerated by iC-MQ – even when the supply voltage is reversed ...

Sensor Signal Conditioning IC Features 14-bit A-to-D


Servoflo is pleased to announce a new sensor signal conditioning IC from ZMD of Germany. As part of the RBic-LiteTM signal conditioning family of IC's, the ZMD31014 is optimized for microcontroller-based sensor systems. Developed for correction of resistive bridge sensors, the ZMD31014 combines high accuracy amplification with analog-to-digital conversion of a differential input. The feature-rich CMOS device is ideal for all types of microcontroller-based portable equipment, such as white goods, wireless pressure transmitters, medical infusion pumps, wearable blood-pressure meters and temperature measurement equipment.


To deliver the highest possible accuracy, the ZMD31014 features a 14-bit low-noise analog-to-digital converter, four times more precise than the 12-bit units found in most devices in this class. On-chip digital logic provides sophisticated second-order error correction for temperature offset, drift, and non-linearity. Performing all of the error correction in the ZMD31014 simplifies designing the rest of the system and helps minimize the overall bill of materials as well as the overall system power consumption ...

New Heavy-Truck Measuring Wheel System


As a rotating 6-component measuring system for wheel and tire test that can be used like a measuring hub, the new RoaDyn S6HT TT (Tire Testing) completes the Kistler range of truck wheel-measuring systems. It is designed for measuring forces and moments on tires for trucks and other heavy goods vehicles.


A modified outer part with an adapter flange and different bolt patterns allows standard wheels to be mounted. As with RoaDyn S6HT measuring systems in operation on vehicles and durability test stands, the TT version offers a measuring range of up to 220 kN in the radial direction and 100 kN in the axial direction. The measuring ranges for torques are: Mx, Mz: max. 40 kN·m and My: max. 60 kN·m. The new system is a high-performance test stand facility which can also be retrofitted on existing test stands at low cost. Its modular design allows for alternating test stand and on-road use ...

New Inch-Wide Ethernet I/O Modules Interface 16 Discrete I/O and Perform Counter/Timer Functions


Wixom, MI: Acromag has extended their BusWorks® line of high-density Ethernet I/O modules for distributed I/O and SCADA with new Model 989EN isolated discrete I/O that also performs counter/timer functions. These space-saving inch-wide modules provide an isolated Ethernet Modbus TCI/IP interface for any input/output mix of up to 16 discrete signals. Inputs sense the status of dry contacts, switches, power supplies, or DC logic. Industrial-grade units have eight 32-bit pulse counters with timers, alarms, and non-volatile memory for metering, totalizing, and low-frequency periodic measurement functions. Outputs control solid-state switching of lamps, horns, and other devices.


Commercial and industrial-grade models have 16 individually configurable bi-directional I/O channels with a 0-28V DC signal range. When configured as inputs, channels accept 2- or 3-wire sensors and active logic switches for use with dry contacts, proximity, namur, or 5-28V DC logic. Inputs detect a level or change of state. Outputs switch 0.5A/channel or 2A total. A “loopback” feature reads back the output state on an input channel. Industrial models add eight counter/timers that can be configured as 32-bit up/down pulse or event counters with non-volatile memory or as 16-bit periodic timers. Each counter supports momentary or latching alarms. The counters have a 250Hz maximum frequency and the timers have resolution to one millisecond ...
