Optical Sensors
Developed in the UK our range of optical sensors provide high-end features at competitive prices. Designed to meet or exceed the industry standards of the markets they are typically used in, such as road and aviation weather systems, renewables energies and weather and climate studies. These sensors can be easily integrated into wider met systems.
PWS100 - Present Weather and Visibility Sensor
CS120A - Visibility Sensor and CS125 - Present Weather Sensor
The CS120A Visibility Sensor and CS125 Present Weather Sensor use tried and tested infra-red forward scatter technology and a proven 42° scatter angle to report Meteorological Observable Range (MOR) for fog and snow in the range 10–75,000 m.
The PWS100 uses a patented 4-beam laser system to measure precipitation and visibility by accurately determining the size, velocity and type of precipitation passing through its measurement volume. This research-grade instrument offers outstanding features and performance.
Identifies 9 basic precipitation types, including drizzle, rain, snow, hail, and graupel
Unique calibration kit available to calibrate particle size and speed measurement to give confidence in reliable measurement of present weather parameters.
Patented four beam, two receiver system directly measures hydrometeor size and velocity
Reports MOR Visibility in range 0-20,000 M with programmable alarm
The CS125 additionally identifies precipitation particles from their scattering properties and fall speeds, and combines this with a temperature measurement to identify the weather type.
Both sensors combine a high specification with a competitive price and are ideal for stand alone applications or in combination with automatic weather stations in road, aviation and wind energy environments.
High performance sensors at a competitive price
Sensor design minimises airflow disruption at measurement volume Low power - suitable for remote application
Two user-configurable alarm outputs which can be used to drive audio or visual alarms using solid state relays
Incorporates automatic dew and hood heaters for all-weather operation
Simple field calibration using optional calibration kit Automatic status check for faults or window contamination
CS135 - Ceilometer
The CS135 LIDAR Ceilometer measures cloud height and vertical visibility for meteorological and aviation applications. Utilising LIDAR (LIght Detection And Ranging) technology, the instrument transmits fast, low- power laser pulses into the atmosphere and detects back-scattered returns from clouds and aerosols above the instrument.
Novel split-lens design for high signal-to-noise ratio, maximized detector sensitivity and extended range Reports cloud height and cover to WMO and ICAO recommendations Competitive pricing Stratocumulus based calibration View data conveniently with Viewpoint software Integrated heater, blower and radiation shield Mixing Layer Height assessment option for air quality applications
