Why WR-3

Cable Free

Get rid of traditional cable-type anemometer. Avoid possible risks from machine operation. Scarlet WR-3 anemometer gives users a wireless wind monitoring solution.

Long Life

4-year battery life of wind speed sensor in all weather conditions. The sensor is designed to use in rigid environments such as dessert, ocean and mountains.

Stay Alert

Never worries about high wind. Develop a safer working environment. WR-3 Anemometer sends automatic high-volume alarms based on user settings.

Wireless Sensor

WR-3 adopts 433/868/900 MHz wireless technology to ensure better performance for barrier penetration and achieving long range transmission. The sensors start sending data when wind cups revolve. The sensor will go to sleep mode when wind cups stop revolving for more than 6 hours. Data transmit rate: every 2 seconds.

The ultra-long 400 meter transmission distance makes WR-3 a perfect gadget to help you monitor wind speed on crane and prevent from high wind risks.

Handheld Receiver

Large LCD display shows digital wind speed, temperature and beaufort chart clearly. Anti-slip rubber on two slides helps users hold the receiver in place during work. User-friendly interface and simple button design allows you to operate the device easily with only one hand.

When the wind reaches a certain speed, an alarm will be triggered, and it will continue as long as high wind is detected. The alarm buzzer located on top of the receiver can effectively warn users at the level of 90 dB.

Low Power Consumption

We use innovative low-power consumption wirless technology on WR-3. The battery power consumption is only 20-30 uA in normal condition and 35 mA peak current during data transmission. 3.6V Lithium battery with 2400 mAh capacity can run the sensor for 4 years.

4-year long battery life reduces the maintenance cost significantly. Low battery indicatior on the display monitor will show up when battery capacity is lowered than 10%.

Abu Dhabi Municipality Heat Stress Awareness Workshop

Scarlet participated in Heat Stress Campaign 2013 with Abu Dhabi City Municipality

This year we have been engaged in Abu Dhabi City Municipality's Heat Stress Awareness Campaign and participated in the Heat Stress Workshop in May 2013. We demonstrated how TWL-1S Heat Stress Detector can assist the site managers to comply with new regulation effectively and efficiently, and many participants invited us to their project sites for live demos.

Over 400 HSE officers and managers attended the workshop. In his speech, the Abu Dhabi Municipality EHS Inspection Team Leader, Mr. Ibrahim Khalid, emphasized that mitigating practice, such as proper hydration, supplement of electrolytes and frequent short rests, must be taken to prevent serious heat illness at worksites with high heat conditions.

Mr. Darren Joubert from Health Authority Abu Dhabi elaborated the importance of heat stress management and the law that companies should follow, particularly the Code of Practice (EHS RI-CoP 11.0 – Safety in the Heat) published by Abu Dhabi EHSMS in April 2013. In the code of practice, it states "Employers that have employees working in high temperature environments shall develop a worksite specific heat stress program that includes a process for assessing environmental conditions utilizing the Thermal Work Limit (TWL) to determine work/rest breaks and water consumption requirements for employees."

Mr. Brent Choate from ODEBRECHT shared his practical experience of heat stress management in the field, provided a thumb of rule to quickly check the symptoms of dehydration and heat illness and urged the audience to implement measures that are required by the new regulation.
