FAQ#016 – Are the vibrating wire piezometers equipped with temperature sensors, or is the temperature sensor an option?
Yes, each vibrating wire piezometer, as every Sisgeo vibrating wire instrument, is equipped with a built-in NTC thermistor YSI 44005 type (3000 Ohm at 25°C). Thermistor is not a option for vibrating wire instruments and therefore there is not additional cost for it.
V-Messwehre und Durchflussmesser
V-Messwehre und Durchflussmesser Codes der Referenzprodukte: QV, QVML, QVLIV, P252Q Durchflussmessung in offenen Gerinnen ist in der Geotechnik, in der Abwasserbehandlung und im Wasserhaltung bei Baugruben und Bauwerken wichtig. Sickerwassermessungen sind notwendig um die Sicherheit von Talsperren, Erddämmen, Schüttdämmen und Betonstaumauern zu gewährleisten. Die Sickerwassermenge einer Talsperre ist vom Seewasserstand abhängig. Sie wird während dem […]
Wasserlichtlote und Pegellatten
Wasserlichtlote und Pegellatten Codes der Referenzprodukte: C112, C112T, HIDR Wasserlichtlote werden zur Ermittlung von Grundwasserständen in Piezometerrohren, Grundwasserpegeln, Brunnen und Casagrande-Pegeln eingesetzt. Die batteriebetriebene Messsonde ist an einem, auf einer Rolle aufgewickelten, Messband montiert. Kommt die Messsonde in Kontakt mit dem Wasser, wird ein Summer (akustischer Signalgeber) und ein Signallicht aktiviert. In dem Moment wird […]
Casagrande und Standrohr-Piezometer
Casagrande und Standrohr-Piezometer Codes der Referenzprodukte: P101, P112, P112A, TCH, TFH Casagrande-Grundwasserpegel werden zur Ermittlung von Wasserdrücken und Wasserständen in durchlässigem Boden und Fels eingesetzt. Der Filter besteht aus hochdichtem Sinter-Polyethylen. Casagrande Piezometer können manuell mit einem Wasserlichtlote und Pegellatten oder automatisch mit einem an den OMNIAlog-Datenlogger angeschlossenen Messwertaufnehmer (Removable Pressure Transducers, Vented pressure transducers […]
Drive-in piezometers
Drive-in piezometers Codes der Referenzprodukte: PK45I, P235I Drive-in piezometers, also called push-in piezometers, are designed for installation in soft clays, organic or fine grained cohesionless soils. The piezometers are pushed directly into the soil using conventional cone penetrometer or drilling rods with adapters. The large diameter nose cone decreases the chance of overpressure while the […]
Titanium piezometers
Titanium piezometers Codes der Referenzprodukte: P235TI Piezo-resistive titanium piezometers are designed to operate in corrosive environments, such as salt water, tailings, and landfills. Resistance to corrosion is provided by a titanium body, ceramic diaphragm, polyethelene or ceramic filter, and acid-resistant signal cable. The robust 4-20mA output is compatible with most readouts (as CRD-400) and data […]
Removable pressure transducers
Removable pressure transducers Codes der Referenzprodukte: PK45C, P252C The removable pressure transducer is designed to measure pore-water pressure through a special Casagrande filter tip. This unique design is especially suitable for long-term monitoring since it allows the instrument to be withdrawn for calibration checks. The removable pressure transducer can be supplied with either vibrating wire […]
Vented pressure transducers
Vented pressure transducers Codes der Referenzprodukte: P252R The vented pressure transducer is designed to provide accurate measurements of water levels in standpipes and Casagrande piezometers. It incorporates a vented pressure transducer for automatic compensation of barometric changes. The transducer can be read with a portable readout as CRD-400 , or for remote data management and […]
Vibrating Wire multipoint piezometers
Vibrating Wire multipoint piezometers Codes der Referenzprodukte: PK20M Multipoint vibrating wire piezometers, also called multilevel piezometers, provide measurements of pore-water pressure at different elevations in the same borehole. Isolation of the pore-water pressure at each elevation is achieved by the fully-grouted installation method. APPLICATIONS • Measurement of ground water pressure at different elevations• Monitoring soil […]
Piezo-Resistive piezometers
Piezo-Resistive piezometers Codes der Referenzprodukte: P235S Piezo-resistive piezometers, also called semiconductor piezometers or strain gauge piezometers, are very accurate pressure transducers suitable for high frequency readings and short term applications. Their robust 4-20mA output signals are easy to read and automate with OMNIAlog and suitable for long-distance transmissions. They can be connected to seismic dataloggers […]
Athens Metro, Greece
A new, modern, fast, comfortable, reliable and safe transport mode has been gradually been in operation since January 2000. Today, 23 Metro Stations are in operation at both METRO lines: Line 2 SEPOLIA – AGHIOS DIMITRIOS/ALEXANDROS PANAGOULIS (red Line) and Line 3. The whole Project is divided into: The Stations of the Base Project: MONASTIRAKI-ETHNIKI […]
Rome Metro B1 Line Rome, Italy
There is a big work in progress in Rome regarding the realization of a new part of the already existing railway B line named “B1 line”. This new branch deviate from Bologna Station towards Africano and Montesacro area, following the way of Viale XXI Aprile, Piazza Annibaliano, Viale Eritrea, Viale Libia, Via delle Valli reaching […]
