Campbell Scientific CVD20 Voltage Divider Specification

The Campbell Scientific CVD20 Voltage Divider is a precision instrument designed for accurate measurement of high-voltage signals. It is primarily used in conjunction with data acquisition systems to safely measure voltages up to 200 VDC. The CVD20 achieves this by reducing the input voltage to a lower, more manageable level suitable for most data loggers and measurement devices, ensuring both safety and accuracy in data capture.

This voltage divider is equipped with a high impedance input, minimizing the loading effect on the measurement circuit and ensuring accurate signal representation. The output voltage is proportionally scaled down, typically in a 10:1 ratio, making it compatible with a wide range of data logging equipment. This capability is essential for applications requiring precise voltage measurements, such as environmental monitoring and industrial process control.

The CVD20 features a robust design with high-quality components that ensure long-term stability and reliability even in harsh environmental conditions. Its compact and durable enclosure offers protection against physical damage and environmental contaminants, making it suitable for outdoor and industrial applications. The device operates over a wide temperature range, maintaining performance consistency across varying environmental conditions.

Installation is straightforward, with clearly labeled connections for input, output, and ground, allowing for quick integration into existing systems. The CVD20 is an essential accessory for professionals needing to extend the measurement capabilities of their data acquisition systems while ensuring safety and accuracy in high-voltage environments. It is an ideal solution for researchers and engineers seeking a reliable method to interface high-voltage sources with low-voltage data loggers.

Campbell Scientific CVD20 Voltage Divider F.A.Q.

What is the primary use of the Campbell Scientific CVD20 Voltage Divider?

The CVD20 is primarily used to measure high voltage signals by scaling them down to a level that can be safely read by data loggers.
