For Aerospace, Military and Marine applications, we offers a wide selection of high reliability RTDs. Weed Instrument precision winds their own platinum and nickel sensing elements, which allows them to produce non-standard resistance curves and values - maximizing performance for our customers. All elements are calibrated to NIST standards and packaged to provide exceptional accuracy, stability and reliability in the harshest environments.

Designed for high reliability and to endure demanding shock, vibration and ambient environments, RTDs can be found in these applications:

• Bleed Air
• Cabin Air
• Engine Oil
• Gear Boxes
• Fuel Systems
• Cylinder Heads
• Climate Control
• Hydraulic Systems

We offer pressure transmitters that work in the harshest environments. Contact The Dupill Group with Questions about our temperature transmitters and sensors.

Ambient Air and Gas Sensors:

Our ambient air and gas sensors measure the temperature of air and gas in an open environment such as a wind tunnel, a jet engine test cell, or a housing for sensitive electronics. A unique feature of our ambient air and gas sensors is their very fast response time.

• Measurement of Cooling Air in Environmental Control Systems
• Jet Engine Test Cells

Fluid Immersion Probes:

Immersion probes are fast-response sensors that are immersed in a closed system of liquid, air or gas. Examples include engine oil, air flow or exhaust gas. Our immersion probes are extremely rugged and are available with hermetically sealed housings.

• Fuel and Hydraulic System Monitoring
• Gearbox Lube Systems
• Environmental Controls

Surface Sensors:

Our mountable surface sensors easily attach to flat or curved surfaces. Their rugged design and small size make them ideal for many applications. Typical surface sensor uses include the measurement of aircraft skin temperature, environmental temperature surrounding critical electronic components, and fluid temperature through the surface of a conduit.
