Ref Descptn Temperature Sensors

RTD (Pt100, Pt1000) °C, °F, Ω (Ohms) Precision temperature in machines

Thermocouple (J/K/T) °C, °F, mV (millivolts) Furnaces, industrial ovens

Thermistor °C, Ω HVAC systems, lab equipment

RTD (Resistance Temperature Detector) -200°C to +600°C ±0.1°C to ±0.5°C Medium Analog (Ohms), 4–20mA High

Thermocouple (e.g. Type K, J, T, E) -200°C to +1800°C ±0.5% of reading Fast mV, 4–20mA Very High

Thermistors -100°C to +300°C ±0.1°C Fast Resistance Moderate

Infrared (Non-contact) -50°C to +3000°C ±1°C or 1% Very Fast Digital/Analog High

Semiconductor Sensors (IC based) -55°C to +150°C ±0.5°C Medium Digital (I2C/SPI) Low temperature sensors are devices designed to measure temperature in harsh or controlled industrial environments. They convert temperature into an electrical signal for monitoring or control purposes. These sensors are critical in maintaining safe and optimal operational conditions in manufacturing, processing, and power generation industries.
