Directional Sensor
Directional sensor Product name: Directional sensorMain technical parameters:Working temperature: 175℃Measurement accuracy: Inclination of 0.1°; Azimuth of ±0.3°; Toolface of ±0.1°Measurement under vibration: Satisfy accuracy of ±0.1°while measuring under vibration of 10g（10~150Hz）Sleep mode: Reduce the total power consumption to 10mA@+15V; 8mA@+28V Product introduction:Directional sensor widely applied for cable borehole and MWD systems. Selecting high accuracy accelerometer sensors and fluxgate sensor, and adopting thick film integrated circuit technology for circuit, it can operate under 175℃. With small volume, compact structure, high vibration resistance, high reliability and good performance, it can be customized according to different demands. Product characteristics:l Maximum accuracy: Inclination of ±0.1°, azimuth of ±0.3°and toolface of ±0.1°within 0～175℃l With accurate measurement under strong vibration of 10g peak value(10Hz～150Hz)l With shock resistance of 1000g, and vibration of 20grmsl Digital data transmissionl With minimum size of Φ31mm×384mm (Four types of standard shape, and can be customized according to users’ demands.Product applications:l Directional drilling and geosteeringl MWD/LWD Technical parameters:Measurement Accuracy:Inclination ±0.1°Toolface±0.1°Azimuth ±0.3°@90°±1°@10°±2°@5° Electrical performance: Input voltage scope±12V~±15V,＋5VInput current50mA@±15V,50mA@+5VLogical levelTTL/CMOSBaud rate9600(default) maximum to 115200Communication proposal ASC Ⅱor binary system Working temperatureTemperature compensation scope0~175℃Storage temperature scope-40℃~185℃Shock1000G,0.5MSVibration while drilling20g Outline parameters:Diameter31mmLength 384mmConnector MDM9SH003P(MDM15PH003F)Matching connectorMDM9PH003L(MDM15SH003L)ER-H2 Orientation ModuleThe ER-H2 orientation unit includes a three-axis magnetometer and a three-axis accelerometer. The operating temperature could reach to 125 degC, we can get the roll, pitch and azimuth value through it. The ER-H2 has a small size of 18mm×20mm×150mm, can be easily installed into a survey probe with a diameter of 25mm.Features: Ø High accuracy: Roll and pitch accuracy is ±0.1º, azimuth accuracy is ±1.0 ºØ Small size: 18mm×20mm×160mmØ Digital serial data outputØ Operating temperature 125 °CØ Both have three-axis magnetometer and three-axis accelerometerApplications:Ø Logging and drillingØ Orientation of buoy and sonar systemØ Magnetic compassTechnical specifications:Azimuth parameterHeading accuracy (Azimuth)±1°Resolution0.1°Repeatability0.05°Inclination parameterPitch accuracy (inclination angle)0.1°Roll accuracy (Tool face angle)0.1°（Inc.<65°）0.2°（Inc.<80°）0.5°（Inc.<86°）Inclination resolution0.01°RangeInc. ±90° Tool face ±180°Physical characteristicsSize (mm)L150x W20x H18Weight100gRS-232/RS485 Interface connector5 Pins aviation plugInterface characteristicsStart delay< 50msMax. sampling rate10 times / secondRS-232 Communication rate2400~92000 baudRS-422, RS-485, TTLOptionalOutput formathexadecimal
