TSY-19 Geotextile Thickness Gauge
The TSY-19 geotextile thickness gauge is designed to measure the thickness of geotextiles and geomembranes accurately under different pressure conditions. It uses a lever principle to amplify the length of the pressure arm, enabling precise measurements within limited space and weight constraints. The device can test samples under pressures of 2 kPa, 20 kPa, and 200 kPa, making it ideal for quality control in production and testing environments.
With a simple yet elegant design, the instrument is user-friendly and suitable for both laboratory and field use. It complies with international standards such as GB/T 13761, T1112-2006, ISO 9863:1990, and SL/T 235-2012, ensuring reliable and consistent results across various applications. This makes it an essential tool for any facility involved in geotextile or geomembrane testing.
Technical Specifications:
- Presser foot area: 25 cm² (diameter: φ56.42 mm)
- Presser foot weight: 5 N (equivalent to 510.2 g for 2 kPa ± 0.01 kPa)
- Secondary pressure: 20 kPa ± 0.1 kPa
- Three-time weight: 200 kPa ± 1 kPa
- Dial indicator: 0–12 mm with a resolution of 0.01 mm
- Instrument dimensions: 730 × 320 × 350 mm (L × W × H)
- Instrument weight: 25 kg
Installation and Testing Procedure:
1. After unpacking, clean the instrument and place it on a stable surface with rubber pads at the corners.
2. Adjust the leveling screws to ensure the instrument is level.
3. Keep the accessory box nearby for easy access to replacement parts.
Testing Steps:
1. Prepare the sample according to the required standard.
2. Lift the cam handle to raise the pressure plate and attached weights.
3. Choose the appropriate presser foot based on the sample thickness (e.g., 0.5 mm for geomembranes, 0.5–5 mm for composite materials).
4. Clean the reference plate and presser foot, align the triangular blade with the V-groove, and install the dial gauge.
5. Place the sample between the reference plate and presser foot, apply pressure, and record the reading after 30 seconds.
6. Repeat for all required samples.
For higher pressure tests (20 kPa and 200 kPa), additional weights are added to the pressure plate, and the process is repeated accordingly.
Note: All results should be manually recorded and analyzed according to the relevant standards.
Usage Precautions:
- Place the instrument in a dust-free, vibration-free environment to maintain accuracy.
- Handle all replaceable components carefully to avoid damage or contamination.
- Do not alter the factory settings unless instructed by a professional.
- If the instrument shows signs of inaccuracy, seek assistance from a qualified technician to prevent incorrect readings.
This comprehensive guide ensures that users can operate the TSY-19 geotextile thickness gauge effectively and safely, delivering accurate measurements every time.
