Frequently Asked Questions

What is the resistance value and tolerance of this RTD sensor?

This Honeywell RTD has a resistance of 1000 Ohms (1 kΩ) at 0°C, conforming to the Pt1000 standard. It offers a high accuracy of ±0.1%, ensuring precise and reliable temperature measurements across its specified range. The element is laser-trimmed for excellent unit-to-unit interchangeability.

What is the operating temperature range and construction material?

The sensor is rated for continuous operation from -70°C to +260°C. It is housed in a durable ceramic case, which provides excellent thermal stability and protection against thermal shock. The attached lead wires are available in either TFE Teflon or fiberglass insulation, suitable for the full temperature range.

How do I interface this 3-wire or 4-wire RTD with my PLC or data acquisition system?

This is a 2-wire RTD sensor with two lead wires. For high-accuracy measurements over longer distances, a 3-wire or 4-wire connection scheme is recommended to compensate for lead wire resistance. You will need to connect it to a compatible RTD input module on your PLC or DAQ system, or use a dedicated signal conditioner/transmitter that provides excitation current and converts the resistance change to a standard 4-20mA or 0-10V output.

Is this sensor suitable for immersion in liquids or gases?

The ceramic sensing element itself is robust, but the standard model with exposed lead wires is not hermetically sealed. For direct immersion, it should be installed within a protective thermowell or sheath. The lead wire insulation (Teflon or fiberglass) is suitable for exposure to many industrial atmospheres and some liquids, but compatibility with specific media should be verified.
