LSQO Series is, a kind of "Quartz pressure type", for enhancing the lightning protection. It using only optical fiber for cable of data transmission and electrical power supply by mounting the "very small optical-electric convertor" inside of the sensor.
Recently in Japan, this type has been used for dam control and flood forecasting and warning systems.
Features
- ・High Accurate Water Level Measurement by Using Quartz Sensor
(Selectable from ±0.05%/±0.02%/±0.01%F.S.)
- ・High Durability by Using an Optical Fiber Cable for Data Transmission and Power Supply
- ・Electrical Power for the Sensor Operation is Generated by "Very Small Optical/Electrical
Converter"(Like a Very Small Solar Panel) which is Mounted inside of the Quartz Sensor
- ・Wide Measurement Range(selectable from 10/20/30/50/70m)
- ・Suitable for Mountainous Stations Where are Frequently Damaged by Lightning Surge
- ・Long Transmission Distance(sensor to coder is up to 1.5km)
Available sites
- ・Important water level station or dam gate where thunder occurs frequently
