HBM, a manufacturer of data acquisition systems, analysis and calibration software, strain gauges, transducers and sensors, has added three more module options for its rugged SomatXR data acquisition system, extending the range of applications and bringing the number of modules to eight. The rugged design of all SomatXR modules make them ideal for applications, environments and operating conditions where laptops and other amplifiers would fail quickly.
The new MX840B-R Universal Module was developed especially for measurement tasks that require the use of multiple transducer types. The measuring amplifier has eight channels for connecting more than 16 different types of transducers, including various forms of strain gauges, piezoelectric transducers, bridge circuits, resistance thermometers, thermocouples, ohmic resistors, and more. It offers a per-channel sampling rate of 40kS/s and a signal bandwidth of 7kHz.
The MX411B-R Highly Dynamic Module is ideal for highly dynamic acquisition and analysis of mechanical measurement quantities. It offers 24-bit resolution and four channels with a maximum sample rate of 100 kS/s per channel, which increases to 200 kS/s in two-channel mode. It supports a variety of transducer technologies, including voltage, standardized current, full- or half-bridge circuit strain gauges, inductive full and half bridges, current-fed piezoelectric transducers, and piezoresistive full bridges.
The MX471B-R CAN Module is designed for connecting the SomatXR data acquisition system to a CAN network. Four individually configurable interfaces receive CAN, SAE J1913, CCP or xCP-on-CAN data and offers the option of using CAN messages as triggers for measurement recordings. In addition, the module provides gateway functionality and can send sensor signals acquired with other SomatXR modules as CAN messages, an option that allows integrating the measurement system with an existing test automation environment in the test bench or with a CAN-based data recorder.
The SomatXR data acquisition system’s rugged design and flexible system configuration make it a good choice for drive and durability testing of construction machines, agricultural machines, and mining machines, structural monitoring, and for summer and winter road testing of automobiles. All three of the new amplifiers have IP65 / IP67 protection ratings, ensuring they’re both dust- and water-tight. An extended operating temperature range (-40 to +80°C or -40 to +176°F) allows putting them to work in a wide range of harsh environments. They meet MIL−STD202G standards and are vibration resistant up to 10g and shock resistant up to 75g. No other data acquisition system in this class is built to survive under these conditions.
