VSR-USB - Vacuum Transducer Piezo / Pirani

Product catalog summary

Overview: The VSR-USB Vacuum Transducer combines Piezo and Pirani sensors to measure absolute pressure from 2000 to 5 x 10^-5 mbar. It is designed for industrial applications requiring compact and robust solutions.

Key Features:

Measurement independent of gas type in low vacuum.
Fast response time of up to 18 ms for shorter clock cycles.
Robust metal housing suitable for rugged industrial environments.
UHV suitability with a metal-sealed stainless steel measuring cell.
Compact construction ideal for space-constrained applications.
Optical status display via LED.
High accuracy and excellent reproducibility over the entire measuring range.
Microprocessor control and temperature compensation ensure stable measurements.
Minimal functionalities for optimal cost-performance ratio.
Digital adjustment to zero pressure and atmosphere via USB connection.
Intuitive handling through software or app.
