Description

Synopsis:

The JMDL-22xxAT Series Smart Digital Crack Meter is widely used for the precise measurement of displacement (width) changes in cracks, joints, and expansion joints of structures within engineering fields such as buildings, roads, railways, bridges, dams, tunnels, and slopes. It is particularly suitable for long-term monitoring.

Product feature:

1. Designed and manufactured based on the inductive frequency modulation principle, it offers advantages such as high sensitivity, high precision, high stability, and minimal temperature influence.

2. The smart digital crack meter features a built-in memory chip with intelligent memory function. Factory-set parameters including the sensor model, serial number, and calibration coefficients are permanently stored. It can save up to 600 measurement results as required, including measurement time, measuring point temperature (for temperature type), absolute displacement value, relative displacement value, and zero-point value.

3. It employs full digital detection, enabling long-distance signal transmission without distortion and possesses strong anti-interference capability.

4. It exhibits good insulation performance, is waterproof, and durable.

5. When equipped with our company's JMZX-3001L Automatic Comprehensive Test System or the Multi-point Automatic Comprehensive Remote Test System, it enables unattended measurement or remote monitoring.

Applications

Widely applied for the precise measurement of displacement (width) changes in cracks, joints, and expansion joints of structures within engineering fields including buildings, roads, railways, bridges, dams, tunnels, and slopes. It is especially suitable for long-term monitoring.
