The d1Plucker and d4Plucker are small, low cost unit that instantly convert vibrating wire (VW) transducers such as load cells, stressmeters and piezometers, into d-Tech compatible instruments.
The d1Plucker and d4Plucker are small, low cost unit that instantly convert vibrating wire (VW) transducers such as load cells, stressmeters and piezometers, into d-Tech compatible instruments.
These VW sensors then become compatible with YieldPoint’s data loggers and radios.
1 channel and 4 channel versions are available. d-Plucker enables YieldPoint’s low cost digital peripheral devices to read (d-Reader), store (d-Logger) or transmit (d-Mesh) data from VW sensors.
The user simply connects the leads of the VW sensor to a terminal block housed inside the unit and then treats the sensor like any other YieldPoint d-Tech instrument. The unit outputs the temperature recorded by the thermistor in oC (0.1oC resolution) and the period of vibration of the wire in µS (0.1µS resolution).
