DMKY-400 Series Joint Displacement Meter Introduction: DMKY-400 vibrating wire joint (displacement) meter is embedded in or on hydraulic structures or other concrete buildings for a long time to measure the opening and closing (deformation) of expansion joints or peripheral joints of structures, and can simultaneously measure the temperature of buried points. The instrument for measuring linear deformation, such as bedrock displacement meter, surface fracture meter and multi-point displacement meter, can be formed by installing supporting accessories. characteristic: 1. The structure is miniaturized, and the maximum outer diameter is only Ф 20mm, wider application space. 2. The output is highly sensitive, and the full range output can reach 4000 words; 3. Design and manufacture high-quality products to ensure long-term stability and reliability; 4. All stainless steel structure, high waterproof performance; 5. Adopt more stable and reliable vibrating wire working principle, digital output, and the measured value is not affected by the cable length; 6. The temperature of the buried point can be measured simultaneously, and the measured value can be corrected accurately; Technical parameters: Model: DMKY-400 Maximum outer diameter dimension (mm): φ 20 × 184 φ 20 × 218 φ 20 × 280 φ 26 × 580 Measuring range (mm): 20 50 100 200 Comprehensive error (% F • S): ≤ 1 Minimum reading K (mm ／ F): ≤ 0.006 ≤0.015 ≤0.03 ≤0.06 Temperature measurement range (℃): - 25 ～ 60 Temperature measurement accuracy (℃): ± 0.5 Temperature correction coefficient b (% F • S/℃): ≈ 0.05 Insulation resistance (M Ω): ≥ 50 Longitudinal stiffness G (N/mm): 0.25 ～ 1.25
