● high measurement accuracy
● Small size and lightweight
Product Introduction:
Boundary dimension
Features:
● high temperature resistant
● high precision
● vibration and impact resistance
● small volume, light weight
● low power consumption
Application:
The DS581D-A high temperature directional sensor consists of a 3-axis fluxgate sensor and a 3-axis accelera tion sensor with built-in temperature compensation. The accuracy of well inclination measurement can reach ±0.2° and the accuracy of azimuth measurement can reach ±0.5° within the range of 0~ 175℃ . In addition, i t can also measure gravity and total magnetic field intensity, gravity toolface Angle, magnetic toolface Angl e, geomagnetism, temperature and other parameters. DS581D-A has the characteristics of small size, high precision, anti-vibration and anti-impact. DS581D-A can correct the Angle deviation caused by mechanical ins tallation through the supporting PC software.
