The image above demonstrates how the NP_Isolator-Pro module is deployed to protect a series of submerged I-P-I (In-Place-Inclinometer) sensor strings on a RS485 digital network.

Each of the individual I-P-I strings are isolated from each other. Any sensor or network failure on one of the I-P-I strings of sensors will not effect the operation of another device after the protection from this device.  

The NP_Isolator-Pro-Pro can be used to prevent ground loops be being formed.

The ground loops can cause all kinds of noise and can in some applications prevent reliable measurements from being made.

Remote field power supply problems are often caused by ground loops.

Introduction

The NP_Isolator-Pro isolator unit is used to protect RS-485 and SDI-12 network based measurement systems from operating in the case of sensor or network failure.

The device can be used to convert measurement operations between devices on SDI-12 and 485 networks and to extend the operating lengths of the networks.  

The NP_Isolator-Pro uses opto-isolation to physically isolate one part of a network from another and to prevent ground loops from causing interference problems to sensor operations and the measurements of the network devices.
