Preamplifier
Preamplifier for Precise Flow and Volume Measurements
To ensure maximum precision and accuracy in flow and volume measurements, VSE has developed the VSI preamplifier, which can be optionally added as needed.
| Properties | Specifications |
|---|---|
| Flow Range | 0,002 to 525 l/min |
| Pressure Range | Up to 450 bar |
| Temperature Range | -40 to +120°C |
| Frequency Range | Up to 50 kHz |
| Viscosity Range | 1 to 1.000.000 cSt |
Consistent and vibration-free measurements
The integrated electronics in the VSI preamplifier significantly enhance signal quality by ensuring harmonic pulse width signals. Through interpolation, individual pulse signals are divided into increments of up to 1/128 of a pulse, resulting in more precise and vibration-free measurements, especially at low flow rates.
A switchable A/B 90° offset enables direction changes during commissioning, while a separate direction signal provides additional information, for example, for single-channel evaluations. Data can be read quickly and easily via the LED status display.
Easy upgrade
The modular system allows for hassle-free upgrading, expansion, and standardisation of existing systems. This increases flexibility, making it easy to implement customised solutions tailored to individual customer needs.
Performance data
The preamplifier supports a wide range of operating conditions, including pressure ranges up to 450 bar and temperature ranges from -40 to +120°C, making it ideal for precise measurements across various applications.
