Quotation Are Invited For Weather Station On Rooftop

Quotation are invited for Weather Station on Rooftop. Last Date for Submission: 02/09/2024 Remarks: Supply, install, commission, and train for a weather station on the rooftop of the SERC lab. The Weather station should include the following parts and specifications, ?A 2-meter high mast used for mounting loggers and other sensors in a weather station application (2-3 inches diam), durable material. ?A cross arm to mount the loggers and sensors on the rooftop. ?Data acquisition system (DAS): mainboard ?used for interfacing sensors and/or communication devices with analog and digital inputs,WIFIand4/5G communication, operating temperature -40 ?C to +70 ?C, humidity 0 to 100%,IP67. The measurement time steps range from at least 20 seconds to1 hour timeintervals. ?Anemometer:fast-response,three lightweight,conical cups mounted on the cup wheel,up to75 m/s (168 mph).Accuracy within 0.4 -60 m/s, Observation range 0.4 to 75 m/s ,Operating temperature( up to 70?C),IP65. ?Wind Vane: counter-balanced, wind vane that measures wind direction. ?Humidityand Temperature Probe:weatherproof housing (IP66),Temperature range: - 50-70?C,Humidity:0-100%.The temperature sensor should be protected using a solar radiation shield. ?Pyrheliometer: solar radiation between 200 to 4000 nm,Sensitivity 7 to 14 ?V/W/m?,Maximum solar irradiance 4000 W/m?, Classification toISO 9060:2018 is Spectrally Flat Class A. ISO first class. ?Pyranometer: Spectral range (50% points) 285 to 2800 nm, Sensitivity 7 to 14 ?V/W/m?,ISO 9060 spectrally flat Class A. Dusttrak Dust Monitor: long-lasting external pump for continuous, unattended, 24/7, outdoor monitoring applications, measure size-segregated mass fraction concentrations corresponding to PM1, PM2.5, respirable, PM10 and PM Total size fractions, Automatic zeroing minimizes the effect of zero drift, Perform in-line gravimetric sampling for custom reference calibrations. ?Sun Tracker, Pointing accuracy< 0.1? passive tracking / < 0.02? active tracking, Operating temperature range -20 to+70 C. The sun tracker should be compatible with the Pyrheliometer Tender Link : https://tenders.squ.edu.om/AllCategs
