DESCRIPTION

The vibrating settlement cell measures settlement and thrust in soil and rock fill. The use of measurement data from the cell can help control further displacement.

The cell consists of a vibrating wire pressure transducer connected through a pair of water-filled nylon tubes to a hydraulic potentiometer located on stable ground.

Vertical movement of the cell relative to its reading location results in a change in liquid pressure within the chamber, which is recorded in meters of water and translated into the amount of settlement or load.

The vibratory settlement cell can take measurements beneath concrete and earth structures in locations that are inaccessible to other types of instruments.

FUNCTIONS

• 15m and 30m ranges available.
• Manhole, trench and low profile types available.
• No vertical rods or pipes to interfere with construction.
• Twin liquid lines allow recirculation of water through the system after installation.
• Does not require access above the sensor to acquire data.

BENEFITS

• Accurate and repeatable readings over long cable lengths.
• Long life, long-term stability and reliability.
• Surge protector prevents electrical damage.
• Connecting cable is firm, shielded and flexible.
• Measurements are not affected by lateral movements.

DESCRIPTION

The PRO Digital Vertical Inclinometer System is used to measure lateral deflections within a pit. The system comprises a biaxial probe, a cable reel and an ultra-rugged field tablet supplied with ‘In-Port Pro’ data capture software.

The probe incorporates MEMS technology which allows highly accurate and repeatable readings, transferred via a digital signal. Bluetooth communication allows for a cable-free data transmission system with no connectors to corrode or break.

The rugged Kevlar® reinforced cable consists of a non-slip cable marker system that, when used in conjunction with the cable gate, provides highly accurate and repeatable depth control.

With all of these features combined, the PRO Digital Vertical Inclinometer System is a rugged and highly accurate system that is lightweight, compact and easy to operate anywhere in the environment.

FUNCTIONS

• There are no connectors between the probe, cable reel and field tablet.
• The probe is made of 316 stainless steel.
• Precision suspension wheel assemblies.
• Bluetooth connection between cable reel and field tablet.
• Accurate and precise measurements using MEMS sensors.
• Repeatable depth control using low wear stainless steel markers and cable gate system.
• Ultra-rugged field tablet allows for easy data transfer.
• Enhanced ‘In-Port Pro’ software for use with Field Tablet for easy data capture.
• Large 8″ high visibility touch screen display.

BENEFITS

• Molded cable connection eliminates water ingress and connection problems.
• Digital signal allows for interference-free data transmission.
• Advanced electronics ensures long, trouble-free use in a harsh environment site.
• Easy data transfer via Bluetooth, direct connection or internet using Wi-Fi or GSM network.
• Waterproof field tablet for continuous use in hostile environments.
• Very long battery life.
• Lightweight and easily portable.

DESCRIPTION

The heavy duty vibrating wire piezometer accurately measures pore water pressures in fully or partially saturated soils.

The heavy duty design prevents casing stresses from affecting readings in extreme installations (dams and high soil stresses). The transducer is equipped with either a low air inlet sintered steel or a high air inlet ceramic filter. It has a cone-shaped part for pushing in installations.

The transducer is made of high quality 316 grade stainless steel and designed for pressure ranges from -50 to 15,000 kPa.

The heavy-duty vibrating-wire piezometer incorporates a surge arrester to provide protection against indirect lightning. The piezometer is also available with a thermistor for temperature monitoring.

FUNCTIONS

• Heavy duty design.
• Utilizes proven vibrating wire (VW) technology.
• Manufactured from high quality 316 stainless steel for long life operation.
• Built-in temperature compensation
• Hermetically sealed.
• High precision device.
• Capable of measuring negative pore pressures to -50 kPa.
• Available with thermistor for temperature monitoring.
• Accurate and repeatable readings over long cable lengths.

BENEFITS

• Long life, long-term stability and reliability.
• Works in extreme installations and pressures up to 15000kPa.
• Fast response to pressure changes.
• Advanced design prevents case stresses from affecting readings.
• Surge protector prevents electrical damage.
• Connecting cable is firm, shielded and flexible.
