Series Description

TD Series temperature sensors from Honeywell respond rapidly to temperature changes, and are accurate to &#177 0.7 &#176C at 20 &#176C - completely interchangeable without recalibration. They are RTD (resistance temperature detector) sensors, and provide 8 Ohm/&#176C 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 &#176C). 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).

Features

• Interchangeable without sensor-to-sensor recalibration
• Very small thermal mass for fast response
• Air or liquid temperature sensing
• Linear temperature sensitivity
• Proven thin film processing reliability
• Low cost
• Long term stability
• 2000 Ohm nominal resistance at 20 &#176C

Typical Applications

• HVAC: room, duct and refrigerant temperature
• Motors: overload protection
• Electronic circuits: semiconductor protection
• Process control: temperature regulation
• Automotive: air or oil temperature
• Appliances: cooking temperature
