Overview

TD Series liquid temperature sensor, anodized aluminum housing, leadwires.TD Series temperature sensors from Honeywell respond rapidly to temperature changes, and are accurate to ± 0.7 °C at 20 °C - completely interchangeable without recalibration. They are RTD (resistance temperature detector) sensors, and provide 8 Ohm/°C sensitivity, with inherently near linear outputs.

The sensing element is a silicon chip with a thin film resistive network pattern. The chips are individually laser trimmed to provide 2000 Ohm nominal resistance at room temperature (20 °C).
TD4A Liquid temperature sensor
TD4A liquid temperature sensor is a two terminal threaded anodized aluminum housing. The environmentally sealed liquid temperature sensors are designed for simplicity of installation, such as in the side of a truck. TD4A sensors are not designed for total immersion.
TD5A Miniature temperature sensor
The TD5A is a subminiature temperature sensor with three leads (The center is not connected).
