1. Overview and General Description

The IR-CZ Series comprises infrared temperature sensors designed for industrial use, featuring a chopper-less design and semiconductor laser targeting to enable precise, non-contact temperature measurements.

2. Specifications

• Temperature Range: -10°C to 3500°C, varying by model and diaphragm size.
• Diaphragm Sizes: φ7mm, φ10mm, φ20mm, φ30mm to control measurement spot size.
• Emissivity: Adjustable remotely or via automatic calculation; critical for measurement accuracy.
• Output Signals: 4-20mA analog output for temperature; contact outputs for alarms and errors.
• Laser Targeting: Built-in semiconductor laser emitter (≤1mW, 645nm, Class 2) for aiming without a viewfinder.
• Alarm Functions: High/low alarms, error detection, and dirty lens detection.

3. Measurement and Accuracy

High accuracy is achieved with resolution down to 0.015% of the measured value and sensitivity at 0.9μm wavelength. Accuracy depends on temperature range and diaphragm size, with specific calibrations for ranges such as 200-2000°C and 300-3500°C.

4. Installation and Environmental Conditions

• Operating temperature for the sensor body: -10°C to 60°C.
• Protection against heat, dust, particles, and sediment via cleaning plugs and window glass options.
• Air inlet and cleaning ports facilitate maintenance of sensor optics.

5. Electrical and Signal Interface

• Inputs include 4-20mA DC for emissivity control and analog inputs for external adjustments.
• Alarm and error signaling via open collector outputs rated at 30V DC, max 50mA.
• Specified connector types for integration.

6. Operational Features and Recommendations

• Laser targeting supports peak hold reset, sample hold, and laser on/off functions.
• Automatic emissivity calculation recommended for varying surface conditions.
• Regular cleaning of lens and window glass is essential to prevent measurement errors.
• Alarm outputs should monitor sensor health and environmental conditions.

7. Mechanical and Dimensional Data

Detailed mechanical drawings and dimensions are provided for sensor mounting, diaphragm sizes, and air inlet ports to ensure proper installation and alignment.

8. Limitations and Precautions

• Measurement accuracy can be affected by environmental factors such as dust, sediment, and furnace wall conditions.
• Temperature range selection must align with diaphragm size and sensor model for reliable readings.
• Laser emission is Class 2; safety precautions are necessary during installation and maintenance.

9. Summary of Key Parameters

10. Maintenance and Troubleshooting

Regular inspection and cleaning of the sensor window and diaphragm are necessary to avoid errors caused by dust, sediment, or damage. The sensor includes self-diagnostic and dirty lens detection features to alert operators.

Conclusion

The IR-CZ Series sensors offer precise, non-contact temperature measurement suitable for harsh industrial environments. Optimal performance depends on correct diaphragm and temperature range selection, regular maintenance, and use of integrated laser targeting and alarm functions.
