Parameter

The company has devoted many years to the development and manufacture of in-situ testing instruments for geotechnical engineering. DN-W1 in-situ testing computer is a new product launched by the company in 2016. It adopts new technology, new technology and new material carefully designed, and has been developed through years of efforts and continuous practice. The instrument has fine structure, beautiful appearance, high test precision, stable performance, reliable power consumption, large storage capacity, strong anti-interference ability and is very convenient to use. It can be used in many in-situ test tests. At present, it is especially suitable for static penetration test, pore pressure static penetration test and cross plate shear test which are widely used in in in-situ test.

1. MSP430F5437A, a novel 16-bit low-power and high-performance microcontroller, is used as the core of the host computer.
2. Using large-scale color TFT high-definition LCD display, the data graph and data display is very clear.
3. Flash memory with large capacity is used to store large and reliable program data.
4. A low-power 24-bit resolution A/D converter is used to automatically zero the input sensor information in the software.
5. The USB interface is set up to connect the U disk, which stores the data in the form of files. Data can not only be read directly on the local computer.
It can be easily moved to the computer to read out.
6. High-strength ABS high-quality engineering plastic moulding shell, beautiful appearance, heat resistance, strong sealing.
7. Setting up three sampling channels and obtaining three test data at one time.
8. Using large capacity lithium battery as power supply is suitable for long-term field operation.

1. The host computer uses 16-bit low-power and high-performance MCU MSP430F5437A as the control center, and 256KB FlaSh memory for storing programs. 16KB static RAM memory is used for data processing and 16MB Flash memory for data collection.
2. The display screen is a 7 inch TFT LCD with a window area of 156 x89 (mm)
3. Three differential input channels, each with a measurement range of 20 mV~+20 mV
4. Linear error of instrumentation measurement system: <0.1%
5. Deep sampling interval: 10cm
6. External probe specifications: static penetration probes of various cross-sections, three-bridge static penetration probes of pore pressure, multi-function wave velocity probes, cross-plate shear probes of various specifications.
7. In-machine data storage: 4096 storage spaces, 1024 data storage at most, 350 multi-holes
8. Voltage and power consumption are about 2W for in-machine batteries and 2.5W for external voltages.
9. In-machine voltage 7.4V 5200mA lithium battery
10. Host Size: 268x168x45 (mm) Host Quality: About 960g
