Colibrys (Switzerland) has announced the release of the MS9001.D, a ±1g MEMS tilt
sensor, to complement its existing family of MEMS accelerometers for down borehole and
directional drilling applications.
MEMS accelerometers are already extensively used in many drilling applications such as measurement while drilling (MWD), logging while drilling (LWD) or horizontal directional drilling (HDD)
where reliability under harsh environment, high stability and low power are required.
According to Jean-Michel Stauffer, VP sales and marketing at Colibrys, “The MS9001.D is one of
the missing elements in our armoury of accelerometers for drilling applications. This new ±1g product
offers the best performances in term of long term stability and precision of the measurement for down
borehole precise tilt measurements. With this product we are able to offer the full range of down-bore
hole products for drilling applications, helping our customers to buy all its requirements from a single
source. and confirming Colibrys’ position as a leading supplier of MEMS accelerometers for drilling
This product benefits from the specialised knowledge and applications experience of Colibrys
accelerometers for drilling applications under quite harsh environments. It completes the current
products portfolio of ±2g (MS8002.D and MS9002.D) and ±5g (MS9005.D) traditionally used for down
borehole and directional drilling applications.
