Wedoany.com Report on Mar 13th, NewTek Sensors Inc. of the USA recently announced the launch of a custom linear position sensing unit, specifically designed to operate reliably in harsh environments with temperatures up to 200°C (approximately 392°F). This innovative sensor utilizes AC-operated LVDT technology. Its sensing element contains no microelectronics internally, effectively reducing thermal drift. It eliminates the need for complex shielding and cooling measures, maintains excellent performance under sustained high temperatures, and simplifies the mechanical installation process.
NewTek Sensors' NTC LVDT signal conditioner provides power and signal processing for these AC LVDTs deployed directly in the hot zone. The external signal conditioner is responsible for demodulating the low-amplitude AC output and converting it into DC voltage, current, or digital signals, facilitating connection to instruments, programmable logic controllers (PLCs), and other control systems. By keeping sensitive electronic components away from the high-temperature area, this system ensures long-term operational reliability and consistent performance.
According to NewTek Sensors, this high-temperature AC LVDT sensor is primarily applied in several key industrial sectors: In aerospace and defense, it can be used for monitoring environmental control system valves, flaps, and actuators, as well as in high-temperature test platforms. In power generation, it is suitable for turbine actuator control and steam valve automation. In oil and gas, it is used for valve position monitoring and actuator feedback in refineries and processing plants. In industrial processing and manufacturing, such as plastic injection molding machines, die-casting equipment, and metal forging presses. In test and measurement systems, including environmental simulation chambers and high-temperature material testing.
NewTek Sensors offers highly customizable design options, including housing structure, stroke length, and high-temperature material selection, enabling the customization of high-temperature sensors according to precise customer specifications. These sensing units can be further developed to adapt to extreme environmental conditions with temperatures up to 1000°C (approximately 1832°F), providing reliable solutions for various demanding application scenarios.
