Infrared Temperature Transmitter 4–20mA: Complete Guide to Non-Contact Temperature Measurement
Infrared Temperature Transmitter 4–20mA: A Complete Industrial Guide An infrared temperature transmitter is a critical device in modern industrial automation where non-contact temperature measurement is required. Unlike traditional contact sensors such as RTDs or thermocouples, infrared transmitters measure temperature remotely and convert it into a 4–20mA signal for continuous monitoring. Non-contact infrared temperature transmitter used for continuous industrial temperature measurement. What Is a Non-Contact Temperature Transmitter? A non-contact temperature transmitter measures the thermal radiation emitted by an object and converts it into a proportional electrical output. Because no physical contact is required, these devices are ideal for high-temperature, moving, or electrically live surfaces. How Does an Infrared Temperature Transmitter Work? All objects emit infrared energy based on their temperature. An IR temperature transmitter uses an optical lens to focus th...
