Aircraft Sensors anti Systems AMETEK Aerospace & Defense offers a highly reliable and cost effective method of sensing the temperature of aircraft fluids, including fuel, engine oil, and hydraulic fluid. TheTJf 07 family of Temperature Sensors is in service on numerous commercial and military aircraft around the globe. AMETEK utilizes proven sensing technologies including Resistance Temperature Devises (RTD) and Type-K Thermocouples for measuring fluid temperature depending on system interface or accuracy considerations. FLEXIBILITY IN MECHANICAL PACKAGE AMETEK’s experience with the unique environmental requirements of aircraft fluid systems provides the customer with the assurance of a low risk solution. FEATURES y Hermetic construction y Threaded fitting or flange mount options y Time response less than 5 seconds y RTD available in 2- or 3-wire configuration y Single or dual element packaging y Various R vs. T curves available y Accuracy typically ± 1°C AMETEK offers a standard, all-stainless steel, hermetic package for value and schedule considerations, but can also tailor the design to your unique requirements also. Mechanical interface options include an industry standard, threaded fluid fitting, or a flange mount for connector keying and error-proof installations. VARIETY OF ELECTRICAL INTERFACES Electrical connections can be accomplished with either a receptacle connector or integral cable assembly with a remote termination. Time response requirements are weighed against the structural requirements for the design. Additionally, AMETEK can offer dual elements for redundancy. Multiple RTD Resistance vs. Temperature curves are available within the same package. Typical elements used include platinum thin film for 100n and 1000n applications. Platinum wire wound elements can be packaged for 100n, 200n and 500n applications. In addition, nickel wire wound elements per MIL-T-7990 standards are offered. EXTENSIVE AIRCRAFT SENSOR EXPERIENCE AMETEK’s experienced engineers provide applications and sensor know-how to optimize your system design. AMETEK Aerospace & Defense has built a reputation for supplying innovative products for the most demanding aerospace applications. AMETEK® AEROSPACE & DEFENSE
