Description

The model R-1 pressure transmitter with diaphragm has been specifically designed for the measurement of viscous, paste-like, adhesive, crystallising, particle-laden and contaminated media, which would clog the pressure channel of conventional process connections. Through its optimised design, the process connection enables cleanability with the wetted diaphragm integrated into the process. Low-maintenance and trouble-free pressure measurement is thus also guaranteed in critical applications with frequently changing media. High accuracy, a robust design, high-quality workmanship and the high flexibility of configuration are key features of the model R-1.

Key features:

diaphragm design prevents clogging in media that could block standard pressure channels High flexibility with customizable configurations Vacuum-tight performance for use in vacuum conditions Robust, high-quality construction for long-term durability

Pros:

Clog-free operation in applications involving viscous or contaminated media Easy cleanability due to optimized design High accuracy in demanding environments

Cons:

May require specialized care during installation to avoid damage to the diaphragm not ideal for general-purpose applications
