Product details
XSJSeries vibrating string earth pressure box
| Product Name: | XSJ series vibrating string earth pressure box |
| Instrument model: | XSJ series |
| Manufacturer: | Beijing Sichuanger Building Testing Technology Development Co., Ltd |
| working principle: | |
| Product Usage: | Measure the total pressure in soil and rock fill engineering, as well as in dam embankments |
| Measure the contact pressure of retaining bodies, bridge piers, pipelines, drilled piles, and tunnel lining | |
| Measure stress in concrete | |
| Product features: | |
| -Long term stability | |
| -Large pressure measurement range | |
| -Can provide different types of sensors: vibrating wire type, resistance strain gauge type | |
| -Made of stainless steel material, corrosion-resistant | |
| -Easy to install and operate | |
| -Built in surge protection | |
| -Triple waterproofing (waterproof street, resin sealing, penetrating connection) | |
| -Frequency signals are easy to process and suitable for remote transmission. Each form of pressure gauge can use pneumatic sensors, resistive sensors, or vibrating wire sensors. Various types of sensors can be read using portable reading devices or data acquisition systems. Usually, each pressure gauge comes with factory calibration data | |
