Torque Measurment

 Currently I am working on a project which involves measurement of torque of a vertical axis wind turbine. This project requires measurement of torque while the turbine is moving. The aim to measure torque is to calculate the size of the generator for a particular RPM.

This is the first time I am using torque measurement sensor. Then I came to know how sensitive this measurement is. Although there is various technology for torque measurement, but strain gauge technology is very popular. The deformation in strain gauge is used to measure torque. There are two type of torque measurement. One is Dynamic or Rotary Torque sensor and other is not-contacting.

I am using Rotary torque sensor to measure the torque of turbine and its RPM also. for RPM I am using proximity sensor.

Remote Monitoring Solutions for Rooftop Solar Power Plant

Remote monitoring solutions for solar power plant are defined as the tools and technology used for monitoring and analyzing the performance of your solar power plant by sitting at your home or office. A plant owner invests a lot of his money in solar power plant, and it is not possible for him visit the plant and checks its functionality. RMS solution solve this problem by providing the performance data in his palm or in his computer. The fault identification and its quick rectification is achieved using RMS solution.

What are the components of RMS?

An RMS solution consists of a hardware and a software. The hardware is a microprocessor/ microcontroller/ PLC based device which collects data from all the devices installed in the plant using communication interface of the devices. It then uploads data to cloud server/ online portal. The major communication interface used in these applications are RS485, Ethernet and major communication protocol used are Modbus, DLMS. 

The software part of the RMS solution consists of a Database which stores data on cloud and a Dashboard for visualization and analysis of the data. The data from the plants are collected at a regular interval of 1min or 5min or 10min. The Dashboard shows live data as well as old data for comparative analysis.



Solar LogiQ! Portal

Although there are various companies in the market which provides RMS solution. Solar LogiQ! portal is RMS portal provided by Holmium Technologies. They have standard and easy to use portal for everyone.


DLOG Series Datalogger
Holmium provides DLOG series datalogger devices for collecting data from field devices. These datalogger have RS485 interface and ethernet interface. They SIM card, Wi-Fi and LAN option for accessing internet.
