Aerospace temperature sensors

Aerospace systems demand precision under extreme conditions—and our temperature sensors are built to perform. From engine components to environmental controls, our solutions deliver accurate, stable measurements in high-vibration, high-temperature, and mission-critical environments.

Our Aerospace Sensing Solutions

We provide temperature sensing solutions engineered for the demands of aerospace applications—where accuracy, reliability, and resilience are non-negotiable. Designed to perform in extreme conditions, our sensors support critical systems from propulsion to cabin climate control.

Thermistors

Thermistors offer fast response and high sensitivity, making them ideal for applications requiring precise temperature monitoring. Available in a variety of resistance values and sizes to suit diverse design needs.

Thermistor Probes

Encased for protection and ease of use, thermistor probes deliver accurate temperature readings in air, liquid, or surface environments. A reliable choice for HVAC, medical, and commercial systems.

RTD Sensors

Known for long-term stability and precision, RTD sensors provide accurate measurements across a wide temperature range. Ideal for critical applications in industrial, medical, and scientific settings.

RTD Probes

RTD probes combine durable construction with high-accuracy sensing, built to perform in challenging conditions. Commonly used in process control, automation, and high-reliability environments.

Custom Sensors

When standard sensors don’t fit, our custom solutions are tailored to your exact specifications. We work closely with you to design and deliver sensors that integrate seamlessly and perform reliably in your unique application.
