LTTsmart - Precision data acquisition system

The precisous measurement system LTTsmart is a consistent further development of our precision measuring instruments. In a new housing, the measuring device is ideally designed for use in industrial environments. As power analyzer, its measurement accuracy makes it ideally for the development of electromobility.

As a precision data acquisition system (DAQ), the LTTsmart is ideally suited for measuring electrical data. Electrical signals can be acquired and evaluated according to internal calculations.

Each module in the aluminum housing consists of two channels each and can be flexibly extended by several modules in different variants of input channels. The flexible selection of the modules allows to design a tailored solution to the respective requirement.

For example, the LTTsmart is perfectly suited for use in power analysis of inverter signals on battery-powered electric motors, in OEM test bench construction or for power quality measurement.

Important facts:

• up to 2 MHz sampling rate per channel (optional 4 MHz per channel)
• 900 kHz bandwidth (optional 1,7 MHz)
• extremely high precision: 0.015%*signal + 0.015%*range
• 24 Bit A/D Converter - extremely low noise and distortion free
• highly synchronous up to 16 channels per device and multiple devices
• 2500 VDC galvanic isolation of all channels
• meets the requirements of DIN IEC 60034-2-3-3
• Voltage and current inputs: up to ±1000 Vrms
• optional ICP®, charge, DMS and/or pulse
• Voltage and current inputs: up to ±1000 Vrms
• compact and robust for operation near inverter

The LTTsmart is the answer to the rapidly increasing demand for broadband and high-resolution measurement technology for airbag test benches and electric motor test benches, for example.

For the quality analysis and monitoring of such systems, a high number of channels, a high signal bandwidth, perfect synchronicity and very fine signal resolution are required at the same time - and sometimes even at very high signal voltages.

The compact LTTsmart 19-inch systems meet precisely these requirements perfectly. By selecting different channel modules, voltages up to 1500 V, currents, sensors such as ICP®, strain gages and charge can be connected to the galvanically isolated measuring channels. These are sampled highly synchronously with up to 4 MHz sampling rate per channel and 24 bit resolution. The analog bandwidth is 1.7 MHz. The amplitude resolution is better than ±(0.015% signal+0.015% range) in all measuring ranges.

In addition, pulse/counter channels are available to record speed pulses with 1.2 ns time resolution. All relevant physical signals, such as torque and speed, are recorded simultaneously with the electrical variables and lead, for example, to a highly accurate efficiency calculation in an electric motor test bench.

The LTTsmart brings the decades of experience of the leading high-end measurement technology specialist Labortechnik Tasler GmbH into the modern test bench world: either with stand-alone software or, thanks to efficient software interfaces, it can be integrated into all existing solutions.

The LTTsmart is also used in many other applications: underwater noise, structure-borne noise, turbochargers, research & development, and much more.
