Product Description

Overview

The Bently Nevada 185450-01 is a versatile industrial sensor designed for high-demand monitoring in gas turbine and industrial applications. It functions as both a high-temperature pressure transducer for dynamic pressure measurement and as a wireless repeater module for ISA100.11a wireless sensor networks. Engineered for reliability under extreme conditions, it supports long-term operational stability, precise signal detection, and robust wireless communication.

Applications

• Gas turbine combustion monitoring, including dry low emissions (DLE) systems

• Detection of pressure pulsations and acoustic modes to prevent mechanical failure

• Industrial wireless mesh network extension for vibration and temperature sensors
