Mini-Inlet for gas and particulate analyzers in the air. Equipped with an easily replaceable anti-insect filter and an anti-water cover to avoid damage to the connected equipment.
The instrument features a mounting stand that can be used directly on walls and other flat surfaces.
It supports a wide temperature range and is therefore suitable for outdoor environments (ambient).
Suitable for DBAP5.
We make air sampling heads (inlets) for the sampling of Reactive Gases and Atmospheric Aerosols to be installed at climate/environmental and air quality observatories.
These air intake systems reflect the ACTRIS and WMO/GAW guidelines for both materials and flow characteristics.
Aerosol inlets, made of stainless steel, have a laminar flow, while those for gases, made of Teflon, have a flow that allows an air residence time in the tube of about 2 seconds.
However, these flows are user-settable for non-standard sampling.
Our inlets have a control unit that not only reads the sampled air temperatures and humidity but also keeps the airflow constant at the chosen value regardless of wind conditions.
Our pick-up heads have very low power consumption (~5W) because they do not make use of energy-intensive pumps, so they can be used even in places where electricity supply is limited.
Articolo New “Smart” Systems for Atmospheric Aerosol and Reactive Gas Sampling in Ambient Air
LEN has developed an integrated system to provide a telemetry and remote control link for Long Duration Balloon experiments. This product, built and tested using the Iridium satellite platform, is MSITel-II, which replaces the previous MSITel model (discontinued in 2021).
MSITel-II provides for acquiring scientific data via the Ethernet interface or from the three serial interfaces (RS232/RS485).
The accepted protocols are:
MSITel-II supports two types of output interfaces:
In addition, MSITel-II has RS232 /RS485 interfaces to interact with other housekeeping equipment or external remote control actuators.
Analogue and digital I/Os are available, and a particular class of output actuators, with safety protocols for uses such as pyrotechnic release, instrument activation or others (high-power and opto-isolated).
The MSITel-II protocols maintain good compatibility with previous versions of telemetry but provide new functionality and information.
All our telemetry runs a metalanguage created by the launcher and/or researcher for their needs, making our telemetry very flexible.
MSITel-II was validated in the Hemera ZPB 2022 launch campaign, using an Iridium Certus/Next terminal.
Technical specifications
MSITel (first version), STRADIUM and STRADIUM-II
MSITel was the first telemetry developed in the early 2000s in close collaboration with IASF Bologna. This telemetry was born to meet not only the needs of ‘experimenters’ but also as primary telemetry that could manage flying (ballast release, GPS localisation, pyrotechnic activation, …).
The main features are:
In a collaboration between ASI-LEN-IASF and others, in 2008 LEN produced a unit capable of handling multiple MSITels (up to 8) simultaneously to increase bandwidth. The MSITel array was called STRADIUM, tested in ASI (MILO base) in 2008, with a demonstration version of the complete system consisting of a “Splitter” unit, the heart of Stradium, and four MSITel units for a total of 8 Trancievers of the NAL Corporation.
In the meantime, LEN has produced significant improvements in MSITel’s firmware and the many ground procedures suitable for the profitable use of the product. ASI has defined, after the Sureca-Bit-10 mission, MSITel as the best telemetry currently available on the market.
This is precisely why other space agencies have decided to use MSITel for their stratospheric applications, either as primary or scientific telemetry (PoGOLite, SORA9, Sureca-Bit-10, etc.).
In 2016, ASI commissioned us to improve STRADIUM by creating an upgraded version (STRADIUM-II) that would allow higher bandwidth data transmission using a TCP/IP link.
To realize STRADIUM-II, we had to make a hardware interface (MSITel-IP) that converts the modem port of MSITel to FastEthernet, allowing data to be sent via TCP/IP. We also had to update the firmware of the telemetry and concentrator to add functionality and improve performance.
STRADIUM-II was used in the Olympus experiment launched from Svalbard in summer 2018.
On that occasion, the system consisted of:
