What if waves and currents could be measured simultaneously at an offshore wind power site? Do you have concerns like this?

The Signature series is an ultrasonic current meter (ADCP) that can simultaneously perform direct measurements of sea surface elevation, measure circular motion current velocity below the sea surface, and obtain current velocity profiles. Using time series analysis and spectral calculations on the acquired data, it is possible to derive various wave parameters, including wave height and wave direction. For water depths exceeding the measurable range for wave measurement, the device can be mounted on a mid-water float for measurement. (*Nortek patented technology) The maximum water depth for wave observation is 150m, making it suitable for surveys at floating offshore wind power sites exceeding 50m in depth. 【Features】 - Direct measurement of sea surface elevation using ultrasonic technology with vertically arranged transducers - Continuous and simultaneous measurement of waves (sea surface elevation, circular motion current velocity) and current velocity profiles (multi-layer current velocity) (Nortek patented technology) - The measurement position of circular motion current velocity can be changed during post-processing (Signature1000/500) *For more details, please download the PDF or contact us.

A compact ultrasonic flow direction and velocity meter capable of measuring wave direction (wave direction, wave height) and multi-layer flow direction and velocity. It also allows for real-time computation output for long-term monitoring applications.

AWAC is a wave measurement device that uses ultrasonic Doppler technology, making it ideal for simple wave observation (deriving wave parameters). It is also equipped with traditional multi-layer current velocity measurement functions (ADCP), allowing for the measurement of both waves and current conditions. For more advanced and flexible measurements of waves and current conditions, we recommend the multifunctional ADCP "Signature" series, which includes AWAC's wave measurement capabilities. AWAC emits sound waves from a transducer located at its center towards the sea surface to directly measure the water surface elevation, calculating wave height and its period. By emitting ultrasonic waves from three transducers, it measures the near-surface current velocity (caused by the circular motion of waves) to derive the wave direction spectrum. By using ultrasonic technology to measure the sea surface, accurate wave height and direction measurements can be achieved even from the seabed at depths of up to 100 meters, which is difficult with pressure gauges alone. Utilizing a uniquely developed SUV method, accurate wave measurements can be achieved even when mounted on a mid-water float (patented). By using a mid-water float in areas deeper than 100 meters, wave measurements can be conducted as long as the main device is kept at a depth of 100 meters or shallower.

A new ADCP equipped with a scientific fish finder sensor (frequency 70~120 kHz)! It can measure both flow and biomass with a single device.

The Signature100 is a completely new ADCP equipped with both a flow direction and velocity profiler (with a measurement range of 400m) and a scientific fish finder sensor (echo sounder). For example, when focusing on the relationship between the behavior of fish and microorganisms (such as krill) in the ecosystem and ocean currents, it was previously necessary to measure acoustic reflections (echograms) and flow direction and velocity data with separate devices. The Signature100 allows for the acquisition of both types of data with just one device. Specifications of the scientific fish finder sensor: Beam width: 15° (70 kHz), 8.7° (120 kHz) Monochromatic pulse: 70kHz, 90kHz, 120kHz Frequency chirping: center frequency 100kHz (BW50%, 70kHz–120kHz) Vertical data spatial resolution: 0.375–4m (1800 data points) Pulse length: 0.5–6ms Resolution: 0.01dB Dynamic range: 130dB

A lightweight, compact, and simple-shaped ultrasonic flow direction and velocity profiler. It also features pressure wave measurement (PUV) capabilities, catering to various measurement applications.

The Aquadopp Profiler is a highly versatile ultrasonic Doppler current profiler (ADCP). There are four types in the lineup depending on the measurement range (distance). It is the ideal ADCP for those who want to simply conduct multi-layer current and velocity observations. In particular, it allows for wave measurements using a pressure gauge to be performed between current and velocity measurements, making it a series with high cost performance. The model equipped with the Z-Cell function can emit sound waves horizontally from the sensor head, allowing for the measurement of flow around the instrument. This feature enables the measurement of flow very close to the instrument, which was difficult with conventional ADCPs. The measurement range is from less than 1 m to over 85 m. The measurement range is determined by the acoustic frequency of each model. (Model name: Maximum measurement range) - Aquadopp Profiler 2MHz: 20m - Aquadopp Profiler 1MHz: 25m (including Z-Cell) - Aquadopp Profiler 600kHz: 40m (including Z-Cell) - Aquadopp Profiler 400kHz: 90m

In facilities operating nurse call systems, we have made bed exit sensors wireless, allowing them to notify in conjunction with the nurse call system. By simply connecting the mat sensor "Foldable Thin Matt-kun," the body movement call "Ugo-kun," and the wheelchair body movement call "Ayumi-chan" to the transmitter HB-RS, you can make the bed exit sensor wireless. The infrared sensor "Just Place Pole-kun" has the transmitter HB-RS built-in. This helps prevent accidents caused by falls, slips, or wandering, contributing to the efficiency of medical operations. 【Features】 ○ Wireless conversion by simply connecting existing sensors to the transmitter HB-WSK. ○ Bed exit sensors notify wirelessly in conjunction with the nurse call system. ○ Up to 5 transmitters can be registered with one receiver. ○ The communication distance between the transmitter and receiver is approximately 10 meters. ◎ For more details, please contact us or download the catalog.

[To the owners of parking lots and parking lot construction companies] "I'm worried about not colliding with pedestrians when exiting the parking lot..." Among vehicle entrances to parking lots, stores, residences, and factories, particularly at entrances facing sidewalks or roadways, there is a risk of dangerous incidents such as collisions with pedestrians or between vehicles. To alleviate such concerns, Hotron proposes a [Vehicle Exit Warning Sensor] that detects vehicle departures using various sensors and alerts the surrounding area with LED lights and buzzers. The system consists of a simple configuration of "sensor" + "controller" + "switching power supply (24V)" + "LED rotating light." *Please note that a separate control panel is required to include the controller and switching power supply (24V) when using the exit warning system. *We kindly ask customers to arrange for the switching power supply (24V), LED rotating light, control panel, circuit breakers, etc. Since it can be retrofitted, it can also be used for existing parking lot entrances. We hope this will contribute to safer vehicle passage for everyone. ◎ For more details, please contact us or download the catalog.
