Sensor de temperatura Honeywell HEL-707-T-0-12-00, série HEL, -75 a +540 °C, caixa de cerâmica

Honeywell HEL-707-T-0-12-00 is a temperature sensor from the HEL series with a ceramic housing and an extended measurement range from -75 to +540 °C. The sensor is designed for industrial and laboratory temperature monitoring where a robust sensing element and resistance to thermal and chemical stress are required. Its ceramic construction provides mechanical strength and stability at elevated temperatures, making it suitable for continuous process monitoring and equipment protection.

Advantages

The ceramic housing offers high thermal resistance and good chemical inertness, helping maintain measurement stability in demanding environments. The wide temperature range covers both cryogenic-adjacent and high-temperature applications, reducing the need for multiple sensor types. The HEL-series design focuses on durability and reliable temperature response suitable for process control systems and laboratory instrumentation.

Suitable for

• Industrial process control and monitoring
• High-temperature equipment protection and thermal management
• Laboratory temperature measurement and testing
• Applications requiring chemical resistance or mechanical robustness at elevated temperatures

When it may not be suitable

This sensor may not be appropriate for applications that require extremely fast transient response if a bare thermocouple junction or ultra-fast thin-film sensor is specified; the ceramic housing can add thermal mass compared with exposed junctions. It may also be unsuitable where electrical insulation or specific connector types not provided by the HEL-series are required without additional adaptation.

Key specifications

• Measurement range: -75 °C to +540 °C
• Housing material: ceramic
• Series: HEL-series temperature sensors
• Intended use: industrial and laboratory temperature monitoring

How to use

Install the sensor so that the sensing element is in good thermal contact with the medium or surface to be measured while following any mounting and wiring guidelines of the system or controller in use. Ensure appropriate electrical connections and insulation according to the instrumentation input type. Allow time for the sensor to reach thermal equilibrium with the measured medium before taking final readings. For process installations, secure the sensor to avoid mechanical stress and consider protective fittings if exposure to corrosive agents or fluids is expected.

What to consider before purchase

• Confirm compatibility with the controller or measurement input type (signal type and wiring requirements).
• Verify that the -75 to +540 °C measurement range covers your application’s operating temperatures.
• Check physical mounting and connector requirements to ensure proper installation with existing equipment.
• Consider whether the ceramic housing and its thermal mass are suitable for the desired response time.

Recommendations

For reliable long-term performance, use the sensor within its specified temperature limits, protect it from mechanical shock, and follow standard calibration intervals for your process or laboratory instrumentation. When integrating into control systems, ensure correct cold-junction compensation and grounding practices to maintain measurement accuracy.
