It could be a problem connected to the power supply given by the readout or logger. When the power supply is in the current loop (2-wire gauge) it is necessary to consider the effect of voltage drop across the shunt resistor on the voltage applied to the gauge. For example, suppose a 4-20mA gauge requires […]
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.
Drive-in piezometers Reference products codes: 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 piezometer is […]
