bison74et-rh-eerste-huisje2Today we received the first titanium housings for the BiSon74ET-RH.

As we already had the 2mm thick sapphire membranes on stock it was quite easy to generate a first impression of what this sensor will look like once completely assembled.  Therefore we would like to present a sneak preview of the sensors today.

Designed in frame of an Artes 5.2 contract (for the use on extendable solar panels of Geostationary telecom satellites) and currently under production, the BiSon74ET-RH is a sunsensor that is to exhibit an unprecedented operating temperature range of +125C till -125C in combination with a very high level of radiation tolerance.

At a mass of less than 25 grams and with a 4 by 4 cm mounting pattern, the sensors are small, reliable and by virtue of the batch manufacturing used for all Bison sunsensors very affordable. The wide temperature range in combination with photodiodes that have been tested up till 1.1Mrad and 10^16 1MeV electrons and are shielded by a 2mm thick sapphire window, this sensor is expected to be able to fulfil the environmental requirements for just about any mission.

The field of view is larger than for the normal BiSon64 sunsensors as the sensors were produced with a specific large volume mission in mind, but a BiSon64ET-RH can be developed quite fast and qualified on basis of similarity in majority if required. for information please contact or give us a call at +31 71 2020 123
