Advanced Non-Contact Infrared Measurement

The PyroUSB leverages infrared sensing theory to deliver reliable, non-invasive temperature readings. Suitable for processes where contact with the measured surface is impractical or unsafe, it is ideal for industry and laboratories requiring high precision and robust performance across challenging conditions.

Flexible Configuration and Data Logging

Easily configure and manage the PyroUSB via a Mini USB 2.0 interface using PC software. Adjust emissivity to match specific materials and applications. Data logging capabilities allow comprehensive analysis and documentation, supporting process optimization and quality control.

Durable and Adaptable to Environment

Engineered with a stainless steel housing and rated IP65 (NEMA 4), the PyroUSB resists dust and water ingress. With an operating temperature range from 0C to 70C and cable lengths available up to 30 meters, the sensor adapts seamlessly to various installation sites and operating conditions.

FAQ's of PyroUSB - PC Configurable Non-Contact Temperature Sensor with 4 to 20 mA Output:

Q: How do I configure the PyroUSB sensor for different applications?

A: Configuration is performed via the Mini USB 2.0 interface. By connecting the PyroUSB to a PC, you can use the provided software to adjust settings such as emissivity, tailor data logging parameters, and fine-tune the device for specific process requirements.

Q: What is the benefit of the adjustable emissivity setting on the PyroUSB?

A: Adjustable emissivity (from 0.20 to 1.00) enables accurate measurement across various materials with differing surface properties. This flexibility allows you to optimize the sensor's performance for metals, plastics, or other surfaces, ensuring precise temperature readings.

Q: Where can the PyroUSB sensor be installed, and what is its environmental rating?

A: The PyroUSB sensor can be installed in industrial or laboratory environments, including areas exposed to dust or moisture. Its IP65 (NEMA 4) rating certifies robust protection against water and dust ingress, providing reliable operation in diverse conditions.

Q: What is the process for obtaining temperature outputs from the PyroUSB?

A: Temperature readings are provided through a linear 4 to 20 mA current loop, outputting signals corresponding to measured temperatures. You can also log and monitor data digitally using the Mini USB 2.0 connection and compatible PC software.

Q: When should I use a non-contact sensor like PyroUSB instead of a conventional contact sensor?

A: Non-contact sensors like the PyroUSB are ideal when the target surface is moving, hazardous, sensitive to contamination, or challenging to access. They are commonly used in applications where fast, maintenance-free and accurate temperature measurement is essential.

Q: What are the usage limitations regarding cable length and operating temperature for the PyroUSB?

A: The PyroUSB comes with a standard 1-meter cable, but extensions up to 30 meters are available for greater flexibility. It operates reliably within ambient temperatures from 0C to 70C, ensuring suitability for most controlled environments.
