Handheld charge amplifier and insulation tester, Type 5811A00

This universal handheld device can be used wherever mechanical quantities are measured with piezoelectric sensors. Piezoelectric sensors produce an electric charge which varies in direct proportion with the load acting on the sensor. The amplifier converts this charge directly into digital values or a proportional output voltage. The battery-powered device is designed for environments and applications where the use of a line-powered charge amplifier in combination with a host computer for visualization and data acquisition of the measurement signal is not suitable. Additionally the handheld device acts also as a service tool for testing the insulation of piezoelectric measuring chains (sensor and cable) as part of regular maintenance work to verify sensor and cable quality.
