📋 Tender Overview
Contract awarded for Measuring devices field lot-0001, title: 1 device fully automatic soil sampling device, description: computer-based system for the automated execution of penetration resistance measurements in soils. the system is designed for the mechanical penetration of a penetrometer for high-resolution capture of soil resistance and for generating reproducible and largely operator-independent measurement data - measurement & control technology: system with constant, predetermined pressure during the penetration process through hydraulic control - integrated penetration resistance monitoring for quality assurance and protection of the sensors - capture of sensor data (pressure (=penetration resistance), soil moisture, optionally: electrical conductivity, optical reflection (see below)) in high-resolution steps of every 1 cm penetration depth, maximum penetration depth of the probe of 80 cm - capture of additional sensor data: penetration speed (preferably continuously) - data acquisition: data interface and storage for field values; the system must have a sufficiently sized internal data storage (min. 5-10 gb) that allows the storage of at least 500 complete measurement profiles including geo-referencing - power supply: autonomous operation via a system-integrated e-power-pack; independent of the onboard hydraulics of the carrier vehicle. - installation & integration: installation on a carrier vehicle (tractor - attachment to three-point hydraulics (category 1 or 2)) or pick-up (like vw amarok) - performance: allows for more precise control of the penetration speed compared to manual operation; minimizes human error factors in data collection. parallel measurement of soil moisture and optionally other soil parameters such as electrical conductivity (ec) or optical reflection (red & infrared), - overspeed control - technical requirements: pressure: at least 135 bar; flow rate: 20 planning basis: mp-3.90 device design as described or technically equivalent. estimated value excluding vat: 56430.00 eur.Measuring devices field
