Introduction

Pressure is a parameter that is commonly controlled in the industry as certain processes require specific environmental conditions for a desired outcome, in this context, it is the force per unit area inflected on the vessel or piping system that holds or transports fluid. These processes rely on pressurized fluids—such as air, water, or specialized liquids—to transmit energy, control machinery, or perform tasks like cleaning, cooling, or mixing. In order to monitor these processes, instrumentation that withstands these pressures should selected. Rheonics offers a variety of sensor probes, rated for different maximum operational pressures. In this article, we will explore the pressure specifications across Type-SR sensor probe variants. 


Pressure ratings for Type-SR sensor probe variants

If the pressure rating of the application is the determining factor for instrumentation selection, the table below can help select the correct sensor probe variant

Note: While the sensor probes can withstand the pressures indicated in the table above, the maximum pressure may be limited by the process connection selected, this is especially the case for Tri-Clamp and Varinline connections.


Note: Pressure ratings also apply for SRD probe variants, visit SRD variants here
