static penetration tester double bridge CLD-3B

1、 Product Overview

The static cone penetration tester developed by our company has high testing accuracy and stable performance, reaching one in ten thousand. It adopts independent three-way A/D conversion, and can perform single, double bridge, cross plate, pore water pressure, super pore water pressure dissipation, and other tests with automatic depth sampling, manual, and time sampling. All memory data will not be lost even without electricity. The exterior and core have undergone a completely new design, with curves and data switching between each other. During the testing process, you can quickly flip up the screen to view the depth data or curves in front of you. All measurement databases stored in the microcomputer can be displayed locally and data can be modified, added, or deleted. Single bridge, double bridge, and cross plate data can be edited

2、 Technical parameters

1. The machine has a small volume, with a main body size of 208x148x58mm, making it easy to carry. It weighs 0.5kg and adopts a fully enclosed structure design. Three independent A/D channels are used inside the machine, which do not interfere with each other.

(1) Three differential input channels, each with a measurement range of -2 to 12.5mV.

(2) A/D conversion resolution: 1/20000.

(3) Linear error of instrument measurement system: ≤± 0.1%.

(4) Sampling time: 10ms.

(5) Depth sampling interval: 10cm.

(6) Time sampling interval: 1s-36h.

(7) External probe specifications: single and double bridge static penetration probes with various cross-sectional areas, hole pressure static penetration probes, and various specifications of cross plate probes.

(8) Maximum recorded depth per hole: 100m.

(9) Internal data storage capacity: a. Single bridge data: 20000m.  

b. Double bridge data: 20000m.

c. Sanqiao data: 20000m.

d. Maximum number of holes: 199.

The display screen adopts a 240x128 large screen dot matrix, full Chinese display, equipped with time display. During testing, it can display three channels of test data and depth display values simultaneously, and can continuously display ten depth test values. And it can switch to display 6-meter depth curves.

2. It is very convenient to call the internal memory of the machine. The RS232 communication port of the machine can directly communicate with the PC and can be converted to a USB interface (or sent to a USB drive for storage; an additional USB drive reader can be purchased)

3. High capacity lithium batteries are used internally, with a working time of more than 50 hours (the capacity can be increased by more than 60 hours as needed), and an external 12V battery can work continuously for more than 10 days. The built-in lithium battery can be recharged more than 400 times.

4. The machine adopts a humanized design in all aspects, implementing modularization and can be divided into (1) single bridge, cross plate, (2) single bridge, cross plate, double bridge, (3) single bridge, cross plate, double bridge, hole pressure single bridge, hole pressure double bridge, allowing users to freely choose and save costs
