Transducers - Cresta

In today’s technology-driven world, the importance of precise measurement and conversion cannot be overstated. Transducers form the backbone of several critical applications, providing accurate measurement and conversion of electrical signals. At Cresta Instruments, our transducers deliver unparalleled accuracy, stability, and performance, making them indispensable in diverse fields such as automation, power management, industrial control, and data acquisition.

What is a Transducer?

A transducer is an essential device that converts an input signal (such as voltage or current) into a proportional and isolated DC output signal. This output can be used for remote monitoring, control, and data logging applications. One of the unique features of Cresta Instruments' transducers is their ability to provide galvanic isolation between the input, output, and auxiliary supply, ensuring maximum safety and signal integrity.

Our measuring transducers are designed to excel in challenging environments where accuracy, reliability, and isolation are paramount. These devices are highly effective for applications in which it’s necessary to convert AC or DC voltage and current signals into a DC output suitable for further processing or measurement.

Tap for enquiry

Current transformers can be categorized based on their application and operational frequency. Below are the three primary types of current transformers, each serving distinct purposes:

SCADA Systems: Transducers are vital for Supervisory Control and Data Acquisition (SCADA) systems, allowing accurate signal measurement and transmission from field devices to central control systems.

Telemetric Systems: For remote monitoring and measurement, transducers ensure accurate and stable signal transmission over long distances.

Energy Monitoring: In power systems, transducers measure current and voltage to monitor energy consumption, contributing to efficient energy management.

Industrial Automation: Transducers ensure precise signal conversion for automated processes, improving efficiency and safety in industrial applications.

High Accuracy and Stability

Our transducers are designed to deliver high precision, ensuring accurate signal conversion even in the most challenging environments. This accuracy is essential for applications requiring reliable and consistent data, such as power monitoring, energy management, and industrial control systems.

Galvanic Isolation

One of the standout features of Cresta Instruments transducers is their 3-port galvanic isolation. This feature isolates the input, output, and auxiliary power supply, providing a high level of safety and preventing ground loops or interference between systems. This isolation ensures that the signal remains clean and accurate, even in harsh industrial conditions.

Universal Power Supply

Our transducers support a universal AC/DC auxiliary power supply (20-70V or 80-300V), providing flexibility and compatibility with various power sources. This feature ensures the transducer can be deployed in a wide range of applications without the need for additional power conversion equipment.

Wide Range of Input and Output Combinations

Whether you are working with AC or DC voltage or current, Cresta Instruments transducers offer a wide range of input and output combinations to suit your application. This flexibility allows you to choose the perfect transducer for your specific measurement and conversion needs.

Designed to Meet International Standards

Our transducers are manufactured to meet IEC 60688 specifications, ensuring compliance with international quality and safety standards. This compliance guarantees that our products perform consistently and reliably in any global industrial application.

Linear Output with Low Ripple

Cresta Instruments transducers provide linear output, ensuring that the output signal is directly proportional to the input signal. This linearity is crucial for accurate signal measurement and conversion. Additionally, the output has low residual AC ripple (0.5%), further improving signal accuracy and reducing noise.

At Cresta Instruments, we offer a comprehensive range of transducers, each designed for specific applications and requirements:
