FAQ#018 – What kind of overvoltage protection is built in the vibrating wire piezometers?

A plasma surge arrestor is wired in parallel with the coil (which is used to pluck the wire). The nominal impulse discharge current 8-20 microsec interval is 10 KA. Impulse spark-over voltage at 1Kv/ microsec: 700 V.

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.

Piezometri multipunto a corda vibrante

Piezometri multipunto a corda vibrante Codici di riferimento: PK45M I piezometri multipunto sono costituiti da una stringa di trasduttori a corda vibrante connessi con un unico cavo multipolare. Particolarmente indicati quando due o più piezometri devono essere posati nella stessa perforazione, vengono installati utilizzando il metodo “fully grouted” che prevede la cementazione dell’intera colonna con […]
