Solid-State Temperature Sensors: Reliable & Affordable

CLEVELAND - Dec. 19, 2024 - PRLog -- Temperature measurements are among the most common data logging applications found across a broad variety of industries including cold chain integrity, medical monitoring, machine/equipment monitoring, environmental monitoring, and in practically every other field. Since temperature monitoring devices are designed for such a wide variety of needs, you must decide on the type of sensors to use.

Solid-state temperature sensors, akin to transistors and integrated circuits, are gaining popularity in various applications. They are well-suited for temperature monitoring in cold chain data loggers, life sciences, and environmental monitoring. CAS DataLoggers' latest White Paper explores the fundamentals and potential advantages of these sensors for your application.

What are Solid-State Sensors?

Similar to thermocouples and RTDs, solid-state temperature sensors convert physical values into electrical signals for measurement. They use diodes, transistors, or voltage references to capture temperature and include signal-conditioning electronics for proportional output. For example, the TMP35 transducer provides a linear 10mV/°C output.

These devices only require a simple voltage or current measurement and linear calculation to convert the output signal to temperature.

Solid-state sensors, named after semiconductor devices, lack moving parts and include built-in circuitry for easy output. They provide a reliable alternative to thermocouples for capturing temperature data and monitoring industrial processes. Newer models are pre-calibrated with traceable data, offering added convenience.

1. There is no need for an additional initial calibration step.
2. If there are multiple sensors in a system, they can be interchanged without a loss of calibration
3. If the sensor ever fails, it can simply be replaced with a new one and the calibration of the temperature measurement system is maintained.

Why Use Solid-State Temperature Sensors?

Solid-state temperature sensors offer high accuracy at a low cost, utilizing the same technology as common electronic devices. Semiconductor sensors, like the AD590, LM35, and TMP36 series, are ideal for specific temperature ranges. Additionally, silicon diode sensors are available for ultra-low temperature measurements.

Solid-state sensors are also ideal for less tech-savvy users, being straightforward in operation. They're easy to connect to a datalogger, noise-resistant, and don't require additional signal conditioning in the form of expensive add-on devices. This sensor type is also easy to use with most types of digital measurement systems like meters or single-board computers.

Solid-state sensors, derived from semiconductor technology, offer a reliable and maintenance-free solution for temperature data capture and industrial process monitoring. These sensors come with integrated circuitry for easy output and are pre-calibrated with traceable data for enhanced convenience.
