Temperature sensor Depending on various parameters, temperature sensors can be classified into many types. For example, based on the transmission method, they can be divided into wired and wireless temperature sensors; based on the output signal type, they can be categorized as resistance‑type, current‑type, voltage‑type, and digital temperature sensors. Commonly used temperature sensor types are typically distinguished by their signal‑transmission methods, with resistance‑signal, current‑signal, voltage‑signal, and RS‑485‑signal sensors being particularly prevalent.
There are two commonly used types of resistive temperature sensors: positive Temperature coefficient of Platinum resistance thermometer PT100/1000 temperature sensor, and Negative temperature coefficient of Thermistor NTC temperature sensor.
The output signal of current‑type temperature sensors is typically 4–20 mA, and it can be configured to cover different temperature ranges according to application requirements.
The commonly used output signals of voltage‑type temperature sensors are 0–5 V and 0–10 V, with accuracies of 0.2%, 0.1%, and 0.05%, selectable according to requirements.
Common digital temperature sensors include the DS18B20, and there are also temperature sensors with integrated RS‑485 output.
The output signal is a critical parameter for selecting the type of temperature sensor; otherwise, it will be incompatible with the downstream data logger or display unit, and temperature data cannot be acquired.
Common types of temperature sensors, classified by style, include standard straight‑tube models, threaded‑mount versions, wall‑mounted units, and more. Temperature sensors are… Non-standard products , specifications, dimensions, installation methods, and other features can all be customized to meet specific application requirements.
