VSC-USB - Vacuum Transducer Piezo

Product catalog summary

Overview: The document describes the VSC-USB vacuum transducer, a chemical-resistant ceramic sensor with FKM sealing. It measures absolute pressure from 2000 to 1 mbar and relative pressure from -1060 to +1200 mbar. The sensor is noted for its high reliability, long-term stability, and measurement independence from gas type. It features a fast response time of up to 20 ms, making it suitable for shorter clock cycles and resistant to dirt.

Specifications: The VSC-USB vacuum transducer operates on a piezo-resistive measurement principle, independent of gas type. It has a maximum overload capacity of 4 bar absolute and offers accuracy of 1% for absolute pressure from 2000 to 1200 mbar and 0.1% from 1200 to 1 mbar. For relative pressure, accuracy is 1% from +1200 to 0 mbar and 0.15% from 0 to -1060 mbar. The reaction time is less than 20 ms, with a voltage supply of 2.7 - 5.25 VDC and a power consumption of max 0.1 W.

Features: The device allows easy connection and adjustment via USB-C, with intuitive handling through software or an app. It provides stable, reproducible measurement values due to a microprocessor controller and individual temperature compensation. Digital adjustment to zero pressure and atmosphere is possible via USB connection, and an optical status display is provided by an LED. The functionalities are minimized to achieve an optimal cost-performance ratio, and the robust metal housing is ideal for rugged industrial environments. Its compact construction is suitable for industrial applications with limited space.

Technical Data: The operating temperature range is +5 to +60 °C, and the storage temperature range is -40 to +75 °C. The digital interface is USB-UART with a range of 9.6 to 115 kBd, 8 databits, 1 stopbit, and no parity. The vacuum connection is a small flange DN16 ISO-KF with a G1/4 female thread, and the protection class is IP40. The device weighs approximately 100 g (VSC43USB).

Accessories: Accessories include a USB-A to USB-C cable with a lock screw, the VacuSniff app for Android, and VGR VacuGraph software. Further accessories and detailed information about the product family are available in the company's brochure.
