Temperature Gauges: Temperature gauges serve as the primary means of visual temperature indication in industrial settings, providing operators with instant feedback on temperature conditions within a system or process. Available in analog or digital formats, temperature gauges come in a variety of designs, including bimetallic, gas-actuated and digital variants, each tailored to specific application requirements and environmental conditions. Bimetallic temperature gauges utilize the differential expansion of two dissimilar metals to produce a mechanical deflection proportional to temperature, offering ruggedness and reliability in harsh operating environments. Gas-actuated temperature gauges employ a gas-filled bulb that expands or contracts with changes in temperature, actuating a Bourdon tube mechanism to indicate temperature changes on a dial display. Digital temperature gauges, on the other hand, utilize electronic sensors to measure temperature directly and provide digital readouts for enhanced accuracy and readability. With their diverse range of designs and configurations, temperature gauges find application across numerous industries, including petrochemical, energy, and HVAC, where temperature monitoring is critical for maintaining operational safety and efficiency.

Non–contact Temperature Sensors: Non-contact temperature sensors offer a unique solution for measuring temperature without the need for physical contact with the object being measured. By utilizing principles such as infrared radiation, laser absorption, or acoustic wave propagation, non-contact temperature sensors can accurately measure the temperature of objects at a distance, offering advantages such as fast response times, high accuracy, and suitability for measuring temperatures in remote or hazardous environments. Infrared temperature sensors, for example, measure the thermal radiation emitted by an object and convert it into a temperature reading, making them ideal for applications such as industrial monitoring, automotive diagnostics, and medical imaging. Laser temperature sensors utilize laser technology to measure the absorption of light by a material, providing precise temperature measurements with high spatial resolution and minimal interference from ambient conditions. Acoustic temperature sensors, on the other hand, rely on the propagation of sound waves through a material to determine its temperature, offering non-invasive and highly accurate temperature measurement capabilities for applications such as material testing, process monitoring, and quality control.
