This is a product from our Acoustic Emission (AE) series. The envelope detection makes it easier to detect the peak values of AE signals. With a time constant peak detection, even brief signals become more visible. The signals are converted to a smoother form, allowing for recording on data recorders with slower sampling rates, which is helpful for AE analysis using externally connected analysis equipment. You can choose a time constant of either 1 msec or 100 μsec. The gain can be selected at 0/20/40 dB. There are models IMA243-05 that supplies a 5V line drive power and IMA243-15 that supplies 15V, both of which can be connected to various preamplifiers. The IMA243 without line drive power can be used for general signal envelope detection. It operates on a mobile battery (USB Type-C 5V), making it usable outdoors, and it is compact and lightweight, offering excellent portability. We also offer custom contract development for acoustic emission-related equipment and signal processing. Please feel free to contact us. *You can view the instruction manual and company information by downloading the PDF below.*

This is a product from our Acoustic Emission (AE) series. It is a pulse generator that generates AE wave pulses for AE testing, also known as a pulser. By connecting an AE sensor and outputting pulses, AE waves are generated from the AE sensor. The selection of pulse voltage can be made via DIP switches or USB commands. Pulse voltage triggers can be selected using a panel push button, automatic repetition, or USB commands. There is a logic output synchronized with the pulse output, allowing for distance calibration by measuring the time difference with AE wave detection. The high-voltage version, IMA241H, can be used when the distance to the AE sensor is long or when the AE signal transmission efficiency is poor. Using this device for AE detection testing of AE sensors allows for diverse evaluation of various AE sensors. It is more stable than the sharp pencil core pressure break method, aiding in quantitative and reproducible sensitivity calibration. It operates on a mobile battery (USB Type-C 5V), making it usable outdoors, and it is compact and lightweight, offering excellent portability. *For more details, please download the PDF or feel free to contact us.*

This is a compact and lightweight digital filter that allows for the removal and extraction of signals by setting and selecting necessary characteristics. This device is a digital filter that restricts the frequency band of signals, realized through digital signal processing. In addition to operating independently, it can be controlled from PC application software via a USB interface. You can select from 64 types of characteristics using the dip switches on the device panel or through the PC application. The 64 filter characteristics can be connected in series, allowing for a band-pass characteristic using HPF + LPF. The characteristics can be swapped, and by loading characteristic files, different characteristics can be achieved. It is also possible to execute arbitrary filter coefficients directly, making it a highly flexible filtering device. It can operate in a local state, functioning solely on the device, or in a remote state, configured from a PC. By connecting an external power source, such as a mobile battery, to the USB power connector to supply 5V, it can operate independently. When connecting to a PC via the USB communication connector, it can operate using USB bus power. Custom specifications are available.

This device measures AE waves to generate and analyze various data. It includes an amplifier, HPF, LPF, A/D converter, and USB interface. The amplification gain is fixed at 20dB for the preamplifier, while the main amplifier can be selected from 0 to 40dB in 10dB steps. The HPF can be set to THRU, fc=30kHz, fc=100kHz, or fc=200kHz. The output for monitoring the signal after amplification and filtering allows for confirmation of the analog signal. Gain, HPF, measurement mode, measurement time, and other settings can be configured via USB, and measurement data can be obtained. Peak values, RMS values, energy, and event counts are measured to generate data. Waveforms can be captured and transferred in real-time via USB. With a compact design that fits in the palm of your hand and operates on a single 5V power supply, this portable AE wave processing device is highly mobile, functioning with a mobile battery or USB bus power.

This device is a frequency multiplier that multiplies the input clock. Within the output frequency range of 1MHz to 10MHz, it can be set to multiply from 9 times to 135 times.

There are two types: IMG242-S and IMG242-P, which branches the power output of our mobile power supply IMG241. Using IMG242-S allows for balanced input using two BNC cables without the need for a balanced input cable (such as twisted pair shielded wire). It is convenient as it enables handling balanced signals with commercially available BNC cables. Using IMG242-P allows for the power voltage to be split into three, enabling the operation of up to three of our preamps or filters powered by mobile batteries. It also allows for power supply from an external source via BNC instead of a mobile battery. It is compact, lightweight, and highly portable.
