Instrumentation solutions improve precision and efficiency  

Instrumentation ensures the accuracy, reliability, and efficiency of industrial processes. Vinit Panchal, CEO, remarks that Libratherm Instruments offers tailored solutions, from calibration standards to cutting-edge controllers and monitoring systems, meeting the highest industry standards and requirements.

How do you ensure accurate calibration and functionality of instrumentation in any system? 

Ensuring accurate calibration and instrumentation functionality is fundamental to maintaining any system’s reliability and precision. Calibration is a process that involves comparing an instrument’s measurements against a known standard to detect and correct any deviations. 

Libratherm adheres to the National Accreditation Board for Testing and Calibration Laboratories (NABL) standards, which ensure the quality and competence of testing and calibration procedures. NABL accreditation guarantees that the instruments used for measurement and testing are calibrated to the highest standards, delivering precise and reliable results. 

The controller device used for calibration is validated by NABL-certified laboratories, ensuring adherence to the highest industry standards. This master device is employed to calibrate other instruments, with its accuracy always one order higher than the instruments calibrated. For instance, if an instrument has an accuracy of 1°, the master device will have an accuracy of 0.1°. Similarly, if the instrument accuracy is 0.1°, the master device will have an accuracy of 0.01°. Calibration is conducted for input and output signals, ensuring comprehensive and precise performance. This meticulous approach ensures that all instruments function correctly and deliver reliable measurements. It is essential for maintaining the integrity of industrial processes. 

How do your cleanroom monitoring systems help maintain environmental parameters in cold storage and data centres?

Libratherm cleanroom monitoring systems ensure the precise monitoring and real-time data logging of critical environmental parameters. Our systems are particularly effective in sensitive areas such as cold storage and data centres. The devices feature an integrated differential pressure (DP) sensor within the indicator. The temperature and relative humidity (RH) sensors can be mounted within the enclosure or connected via extended cables of up to 5 meters. These systems are equipped with alarms and buzzers that promptly signal any discrepancies in measurement or monitoring, ensuring immediate attention to potential issues. 

The THP series has built-in flash memory capable of storing up to 30,000 real-time records. Each indicator also features a real-time clock to log T+RH+DP values at regular, programmable intervals. Digital interfaces such as RS 485 or Ethernet are incorporated for enhanced operational efficiency, allowing seamless communication with Building / Environment monitoring systems for centralised monitoring. These features collectively ensure that our monitoring systems provide reliable visibility and control over environmental parameters in sensitive areas. 

What benefits do PID controllers offer in precision applications besides temperature control? 

PID controllers are integral to industrial control systems. They regulate crucial process parameters such as temperature, pressure, flow, and speed. PID controllers maintain stability and accuracy within a control loop by utilising inputs from sensors and transmitters, making them a preferred choice for various applications. 

Beyond temperature control, Libratherm PID controllers also excel in precision applications requiring fast-acting control of voltage and current. The specialised PID controller DVC-966 features a distinct algorithm for maintaining voltage and current in DC rectifiers, ensuring accurate adjustments. The benefits of PID controllers extend beyond their core functionality. They are highly customisable to meet specific client requirements and logic, providing flexibility for various industrial needs. Additionally, models with IoT interfaces and PC software utilise the RS-485 digital interface, allowing users to monitor and control parameters directly from their computers. These features make Libratherm PID controllers versatile and reliable tools in precision applications, enhancing process control and operational efficiency across various industries. 

Please discuss the role of thyristor triggering cards and power controllers in industrial automation and the industries that benefit from it. 

Thyristor-triggering cards and power controllers play a crucial role in industrial automation. They provide versatile solutions for managing power delivery and ensuring precise control across various equipment. Original Equipment Manufacturers (OEMs) and machine builders construct thyristor stacks using our thyristor triggering cards. These SCR triggering cards are equipped with features such as built-in current limit and overload protection, automatic phase sequence detection and synchronisation, and automatic cut-off in the event of overtemperature. These features are invaluable in the design of reliable and efficient thyristor power controllers. 

On the other hand, Thyristor power controllers are ready-to-use modules that integrate SCR control electronics with appropriately rated SCR devices. They are for precise, accurate, consistent temperature or power control within a closed-loop system. When connected to a heater load, these controllers receive processed signals from a PID controller based on sensor data. With the help of a thyristor power controller, energy waste is reduced, process control is enhanced, equipment lifespan is extended, and maintenance costs are minimised. 

Industries such as Heat Treatment Plants, Glass Manufacturing, Furnaces and ovens, Pharmaceuticals, Jewelry Production, HVAC Systems, Air Handling Units (AHU), Steel Industry, Research and Defence Institutes, and Automation benefit from using thyristor-triggering cards and power controllers. These industries leverage the capabilities of thyristor-triggering cards and power controllers to achieve greater efficiency, reliability, and precision in their processes.
