Product Overview

The Bently Nevada 136180-01 is a dual-function solution encompassing a Magnetic Pickup (MPU) Speed Sensor and a 3500/92 Communication Gateway Module. Designed for critical machinery monitoring and industrial network integration, it provides reliable RPM measurement and data communication for the 3500 Series monitoring systems.

The Magnetic Pickup delivers accurate rotational speed signals without requiring external power, while the Communication Gateway enables seamless connectivity between 3500 Series I/O modules and Ethernet networks, ensuring efficient real-time system monitoring and control.

Product Description

Magnetic Pickup (MPU) Sensor

The 136180-01 MPU is a passive, self-generating sensor used to detect the rotation of shafts by sensing ferrous gear teeth or similar discontinuities. It produces an AC voltage proportional to shaft speed, providing input for tachometer and overspeed protection systems. The stainless steel construction and hermetically sealed design allow operation in extreme temperatures and harsh industrial conditions.

3500/92 Communication Gateway Module

This module serves as a network interface for 3500 Series I/O modules. It features a standard RJ45 connector and supports 10 Mbps communication for real-time monitoring. Optimized for low power consumption (5–5.6 W) and a wide operating range (-30°C to 65°C), it ensures reliable integration of multiple sensors and control points into centralized industrial networks.
