LTT24 - fast precision measuring device / transient recorder


The all-rounder from LTT: LTT24 precision measuring device and transient recorder!

This highly complex data acquisition device, which can work with a very high sampling rate and high memory depth, comes with associated software that does not require a driver.

LTT24: Highly precise measurement device / transient recorder

Are you looking for a high-precision measuring device with synchronous data transmission? Then the LTT24 is exactly the right data acquisition device for you! The LTT24 is the perfect choice, especially when a transient recorder is needed to record short-term events with high temporal resolution.

The measurement inputs of the LTT24 impress across the entire bandwidth from DC to 1.7 MHz with both extremely low noise and extremely low distortion - with both points the LTT24 is clearly the market leader as a precision measurement device. This is ideal for any measurement task, but above all for measurements in which even the smallest measurement deviations or measurement errors must be prevented.

Distortion and noise combined are below -100 dB and therefore offer an ENOB (effective number of bits) value of 16 bits over a wide range of frequencies and amplitudes. Coupled with an integrated AD converter with 24-bit resolution and highly synchronous sampling at 4 MHz per measurement channel, the LTT24 sets high standards for measurement tasks where extremely high precision is a key factor for successful analysis. To guarantee maximum safety, measuring channels are galvanically isolated from each other and the housing.

The internal power supply of the precision measuring device operates highly synchronized to half the ADC clock rate and thus remains invisible over the entire bandwidth from DC to 2 MHz. The common-mode rejection of the differential amplifier - which is crucial for suppressing external, usually high-frequency interference via the sensor cables - allows adjustment from DC to over 1.7 MHz bandwidth to better than -100 dB at the touch of a button.

Thanks to the patented technology, the measured values from all channels are recorded highly synchronously even at full sampling rates and either stored on the internal hard disk (SSD) or transferred directly to a connected computer. There, the measurement data can be visualized, analysed and saved. Numerous interfaces between our software and other software packages also allow it to be used in existing environments.

Transient recorder for highly synchronised data processing

Transient events are rapid, significant changes in the measured values. These state changes can expand the understanding of systems through analysis, e.g. in electronics, thermodynamics or mechanics. Measuring devices that are optimized precisely for such transient events are called transient recorders.

The LTT24 is ideally designed for such measuring tasks, as the fast internal processing of the measured values enables the data to be transferred to the PC in real time. High data transmission requirements are therefore no problem.

In addition, analog output is also possible via 20-bit DAC with up to 2 mega samples/second per channel.

Flexible application

As a modular data acquisition device, the LTT24 offers several channel variants: There is the robust housing for 4, 8 and 16 channels as a portable variant and an industrial variant for 32 channels in a 19-inch housing. In addition, several LTT24s can be synchronized with each other.

The LTT24 allows different signal processing thanks to the functionality of the preamplifier. Individual connection options for a wide range of sensors (e.g. voltage, current, ICP®, charge, strain gauge, LVDT, PT100, etc.) can be connected as required. All measurement channels offer stable sensor supplies up to the MHz range - and more precise than the measurement resolution of -117 dB!

Conclusion: The flexible selection of channel numbers, together with the variable selection of sensor connections, enables a wide range of options and applications. The LTT24 can therefore be used as a transient recorder, sensor recorder or PC-supported data collector.
