I404 - 4 Channel Charge Integrating Digital Electrometer
Mô tả
The I404 is intended for the measurement of small charges or corresponding currents (from pA to µA) generated by devices such as ionization chambers, in-vacuum beam position monitors, proportional chambers, and photodiodes. Four input channels make the I404 particularly well-suited to four-quadrant electrode systems used for beam centering. The I404 includes an integrated high-voltage supply, suitable for biassing detectors.
See the I400 for an electrometer offering high voltage biased inputs, suitable for thimble ionization chambers.
See the IC101 for an electrometer with a single channel.

Integrated High Voltage
- Avoids the need for a separate external HV supply.
- Precise programmable voltage control.
- Choice of polarity, positive or negative, and range up to 3000V depending on the product.
- Shared ground with measurement electronics to eliminate ground loops.
- Short circuit protection and redundant output voltage monitoring.
Fiber Optics
Pyramid transmits measurement data over fiber-optic cable instead of copper, keeping signals immune to electrical interference. Our radiation-hard fibers have minimal light attenuation, enabling fast, reliable messaging across enormous distances.
IG2 EPICS Support
Integrate device data collection and configuration into an EPICS system, without writing a single line of code using IG2.
- Runs on Windows and Debian Linux
- Change PV names with simple XML configuration
- Connect to multiple Pyramid devices at once
- Add custom scale factors and offsets on a PV basis
- Never have to recompile
- Professional Pyramid support for bugs and features
