What is Logsheet?

A logsheet is a paper-based or digital form commonly used in asset-intensive industries.
This form is used to record, collect, and retain equipment data during routine inspections, walkarounds, and regular checks of machinery and assets.
Each piece of equipment typically has its own dedicated logsheet. Maintenance and operations personnel use these forms—with predefined data fields—during routine rounds to record equipment-specific parameters such as temperature, vibration levels, flow rate, current (amperage), and similar metrics at scheduled intervals.
Collecting this information in logsheet forms—along with details such as the date of data entry, the person who recorded it, the approver, form ID, deviation levels, and more—provides maintenance and operations managers with a comprehensive overview of equipment conditions and the routine inspection activities performed.

Say goodbye to manual and paper-based logsheets.

What Is Logsheet Software and Why Does It Matter?
In many asset-intensive industries—such as power plants, steel manufacturing, refineries, petrochemicals, and beyond—routine logging and monitoring of key equipment performance parameters around the clock is essential. One of the core responsibilities of operations teams is to inspect critical equipment regularly and accurately record operational data such as temperature, vibration, pressure, or current.
Traditionally, many companies rely on manual data entry using paper-based logsheets. However, this method is time-consuming, prone to human error, and lacks the accessibility needed for timely data retrieval and effective analysis. Moreover, manually logged data often cannot be efficiently leveraged for triggering scheduled maintenance activities such as PM (Preventive Maintenance), CBM (Condition-Based Maintenance), or PdM (Predictive Maintenance). The sheer volume of recorded values and the need to sift through paper archives make data extraction both time-consuming and, in practice, nearly impossible.
The Pegahe Aftab Logsheet Software offers a reliable, efficient, and cost-effective solution to these challenges. Equipped with an Android application that supports both online and offline modes, it transforms the entire process of equipment data logging. From real-time data entry to report generation and actionable insights, the software delivers a fully integrated platform that automates the collection, storage, and application of operational data—helping organizations gain better control over asset health and maintenance planning.

Before Using Pegahe Aftab Logsheet Software

Challenges of Manual Logsheet and Checklist Entries and Key Questions

Have you ever been able to fully utilize the data you painstakingly and regularly collect from critical and sensitive equipment multiple times a day?

Have you ever been able to provide this collected operational parameter data in real-time, effortlessly, to all authorized personnel, with no limitations on the date?

Have you ever had the ability to define formulas and schedule work orders (PM, PdM, CBM) based on the recorded values of these operational parameters?

How many days does it take for the data collected using various paper-based methods or existing handheld devices to be processed and made accessible to others?

Do you believe the current controls in place to ensure the accuracy of recorded equipment performance data—whether during entry by the operator or later checks by shift engineers and other experts—are reliable and comprehensive?

If you are using old equipment for recording device values: Have the numerous issues, such as a difficult user interface, challenges in data transfer, frequent port failures, and high maintenance costs, not become overwhelming for you?

Yazd Taban Power Plant

One of the obvious needs at Taban Power Plant was to eliminate the manual logging of equipment data on paper log sheets. Manual and paper-based logging was a time-consuming process prone to errors in recording and processing the operational data of equipment. Additionally, it was essential to not only use software for equipment data recording but also to make the most effective use of this data in maintenance decision-making processes and actions. Moreover, it was important to ensure that reports required by each department were easily accessible to managers. After the implementation of the logsheet solution, Taban Power Plant was able to successfully achieve many of these goals and requirements.

The Shobad Kahnuj Combined Cycle Power Plant, as the largest private investment in the southern part of Kerman province, was inaugurated in 2015 with the goal of supplying part of the electricity needed for the southeast region of the country, improving and stabilizing voltage, and enhancing the distribution and transmission network in southeastern Kerman. The implementation of the Logsheet software solution by Pegaah Aftab enables the plant to monitor equipment status precisely and access their performance history (and make decisions based on that data). This helps increase the reliability and lifespan of these valuable organizational assets, while also automating the maintenance and operational processes, improving work efficiency, and preventing resource wastage.

Is an industrial handheld device required to use this solution?

No! This solution runs on all Android devices with Android 6 or higher, and there is absolutely no need to purchase any specific device.

No! Data transfer via cable is time-consuming and effectively prevents the collected data from being quickly shared with stakeholders. Moreover, using connection cables reduces the lifespan of equipment data logging devices. In the Pegahe Aftab logsheet solution, data is transferred wirelessly without requiring any user intervention.

No! The Pegahe Aftab Android Logsheet solution operates independently and does not require any maintenance software to function. However, using both systems together offers significant benefits to the customer.

Yes. The Pegahe Aftab Logsheet software can be fully integrated with the Pegahe Aftab Maintenance Management System.
