Frequently asked questions
Answers to the most common questions about our products and services
It serves charge accelerometers. Its differential input supports balanced sensors such as 8315 and 8324 to reduce electromagnetic interference effects.
No. Versions differ in gain, filters and supply. For example, the manufacturer table includes 1 and 10 mV/pC; select by the complete type number.
No. The version table includes −24 V, +12 V and +24 V depending on suffix. Check the actual version before connecting power.
The amplifier itself is IP20. The manufacturer requires DIN-rail installation in an electrically shielded IP65 junction box for environmental and interference protection.
Check charge gain, version filters, output-voltage range and DC offset against sensor sensitivity and instrument input. Amplifier gain in mV/pC differs from sensor charge sensitivity per acceleration unit.
