Overview

The HEL-705-U-0-12-00 is a high-accuracy thin-film platinum Resistance Temperature Detector (RTD) featuring a 1000 ohm base resistance. This sensor is designed to provide linear temperature monitoring across a wide range and comes pre-wired with 12-inch leads for easier integration into remote housings or probes.

Why Choose This Part

This RTD offers a high 1000 ohm nominal resistance, which reduces the impact of lead-wire resistance errors compared to standard 100 ohm sensors. Its thin-film platinum construction ensures excellent long-term stability and 0.2 percent interchangeability for precision measurements.

Applications

HVAC System Monitoring
Precision air and fluid temperature sensing in commercial climate control systems.
Industrial Process Control
Monitoring temperature in chemical processing or food and beverage production where RTD stability is required.
Motor and Transformer Protection
Embedding within windings to detect overheating and prevent equipment failure.

Getting Started

To interface this sensor, use a high-resolution ADC with a precision current source or a bridge circuit configuration. Ensure the excitation current is kept low, typically below 1mA, to prevent self-heating errors that can degrade accuracy.
