Mag-Instruments UG - Portable Spinning Magnetometer (PSM) for Magnetic Field Measurement
The Portable Spinning Magnetometer (PSM) is engineered for precise and efficient magnetic field measurement. This instrument employs a spinning mechanism that enhances its ability to accurately detect and measure the magnetic field vector components, making it an essential tool for geophysical explorations, laboratory applications, and fieldwork. Its portability and robustness make it suitable for both indoor and outdoor environments. The PSM's design ensures that it can handle various environmental conditions while maintaining high accuracy and resolution. The device can be utilized to perform detailed magnetic surveys, identify magnetic anomalies, and support research in magnetometry. Additionally, the design includes considerations for user convenience, with features such as easy calibration and data retrieval interfaces. The instrument's demagnetization capabilities further extend its range of applications, especially in the removal of remnant magnetization from samples before measurements are taken.Portable Spinning Magnetometer (PSM) is the world’s most compact and affordable device for measurement of remanent magnetization of standard, homogeneous one-inch core samples. It is also the only device on the market which has ability to indicate the level of the sample's homogeneity. PSM has a rugged and lightweight design which together with the shipped tripod and battery lasting for 2-5 days [1] makes it a perfect device, not only for a tabletop, but also for a field work.
PSM can be operated standalone and remotely from PC. The device is equipped with a graphic LCD display and control knob which facilitate the standalone operation. They allow for full control of the device without need to connect to an external computer. The device can also store results of measurements on the inbuilt SD card, so that the user does not have to note down the measurement results. Alternatively, the device can be fully controller from PC connected through USB interface. We provide a Windows based software that allows for control of the device and storing of the measurement data. On special request, we can also provide library that will allow for smooth integration of PSM with the customers’ custom laboratory software.
The device was designed with ease of use and maintenance free operation in mind. The inbuilt gravity compensation mechanism allows for smooth and effortless sample exchange. The calibration is performed with a single calibration sample and there is no need for any mechanical adjustment of the device. The system is also automatically adjusting the attenuation and number of rotations depending on the sample’s strength. Thanks to sensor which detects lowered sample the measurement progresses automatically through different sample orientations, bringing the necessary user actions to rising and rotating the sample only. Throughout the measurement there is no need to press any button. All these features significantly simplify and accelerate the measurement process.
