Product Description

Customizable High Resistance Mineral Insulated RTD Sensor Cable

An RTD (Resistance Temperature Detector) is a precision sensor whose electrical resistance changes predictably with temperature variations. As temperature increases, the sensor's resistance rises proportionally. This well-defined resistance-temperature relationship ensures consistent, repeatable performance over time. RTDs are passive devices that require external electronic instrumentation to measure resistance by applying a small electrical current (typically 1 mA or less, with a maximum of 5 mA to prevent self-heating) and monitoring the resulting voltage output.

Understanding RTD Sensors

RTD stands for Resistance Temperature Detector, also known as a resistance thermometer. These precision sensors measure temperature by utilizing the predictable relationship between electrical resistance and temperature in conductive materials. Typically constructed from fine platinum, nickel, or copper wire wound around a ceramic or glass core, RTD sensors provide accurate and reliable temperature measurements across various industrial applications.

Industrial Applications

RTD sensors serve critical temperature monitoring functions across multiple industries:

Automotive: Engine temperature monitoring, oil level sensing, intake air temperature measurement
Communication & Instrumentation: Amplifier temperature sensing, transistor gain stabilization
Industrial Sectors: Power electronics, computer systems, consumer electronics, food processing, medical electronics, military, and aerospace applications
