Detailed Description

The CVD20 provides 6 single-ended or six differential channels for connecting sensors that have a higher voltage output than what a datalogger can measure. The CVD20 contains resistors that divide the sensor's signal voltage by a factor of 20.


Number of Channels 6 single-ended, 6 differential
Division Ratio 20:1
Resistors 1 kohm and 19 kohm
Ratio Tolerance ±0.1% (@ 25°C)
Dimensions 9.4 x 6.9 x 3.8 cm (3.7 x 2.7 x 1.5 in.)
Weight 91 g (3 oz)


Datalogger Considerations

Each CVD20 can be wired to divide six differential or six single-ended voltage levels.


When using CRBasic, the CVD20 is measured with either the VoltSE or VoltDiff instruction. When using Edlog, the CVD20 is measured with either Instruction 1 (SE Volts) or Instruction 2 (DiffVolts).
