Infrared Temperature Sensor CKHW Series User Manual

1. Introduction

The CERTEON CKHW Series Infrared Temperature Sensor is a non-contact temperature measurement device designed for continuous industrial monitoring. It detects infrared radiation emitted from the target surface and converts it into a standard industrial output signal. This sensor is suitable for integration into automation systems via 4-20 mA, voltage, or serial communication outputs. It is primarily intended for non-metal surface temperature measurement in industrial environments.

2. Specifications

The following table details the key specifications of the CKHW Series Infrared Temperature Sensor:

3. Applications

The CKHW Series Infrared Temperature Sensor is suitable for a wide range of industrial applications, including:

• Food processing
• Textiles
• Plastics
• Ceramics
• Machinery such as tea dryers and pancake machines
• Equipment involving coal or graphite
• Measurement of surfaces like glass, water, and chemically treated metals

4. Features

Key features of the CKHW Series Infrared Temperature Sensor include:

• Advanced infrared optical lens for improved accuracy.
• Millisecond-level response speed with multiple output options.
• Non-contact design for hard-to-reach or mobile targets.
• Compatible with a wide range of accessories for added functionality.

5. Setup

5.1 Preparation

• Ensure the selected temperature range and output signal match your application requirements.
• Confirm that the power supply voltage complies with the sensor rating (12-36V DC standard, customizable 5-36V DC).
• Verify that the target surface is non-metallic. If measuring metal surfaces, apply high-temperature resistant paint or tape to the measurement spot to ensure accurate emissivity.
• Ensure the target diameter exceeds 10 mm.

5.2 Installation

• Mount the sensor using the M18 threaded connection. Secure firmly to avoid vibration.
• Maintain a clear optical path between the sensor lens and the target surface.
• Avoid installation near strong electromagnetic interference sources.
• Connect wiring according to the selected output configuration. For 4-20 mA two-wire systems, connect in series with the control loop according to industrial standards.

6. Operating Instructions

6.1 Operation

• Power on the device after completing wiring checks.
• Allow stabilization time as required by the system.
• Align the sensor perpendicular to the target surface for optimal accuracy.
• Ensure the object is stationary or moving slowly. The device is not suitable for high-speed moving targets.

6.2 Data Reading

• For 4-20 mA output, interpret the current signal according to the configured temperature range.
• For voltage or RS485/RS232 output, configure the receiving device or PLC according to communication protocol settings provided by the seller.
• Use compatible display or control instruments if required.

7. Maintenance

• Keep the optical lens clean. Use a soft, dry cloth or industrial lens tissue for cleaning. Do not use corrosive solvents.
• Store the device in a dry and ventilated environment.
• Avoid mechanical shock during transportation and storage.
• If the device will not be used for an extended period, disconnect from power supply and store in original packaging.
• Do not disassemble the device.

8. Troubleshooting

This section addresses common issues and their potential solutions.

8.1 Common Issues & Solutions

• Inaccurate Readings on Metal Surfaces: This sensor is designed for non-metal surfaces. For metal measurement, surface treatment (e.g., applying high-temperature resistant paint or tape) is required to ensure proper emissivity.
• No Reading for Fast-Moving Objects: The device is not suitable for high-speed moving targets. Ensure the target is stationary or moving slowly.
• No Output Signal: Check wiring connections according to the selected output configuration. Ensure the power supply voltage is within the rated range (12-36V DC).
• Sensor Not Powering On: Verify the power supply connection and voltage. Ensure correct polarity if applicable.

9. User Tips

• For optimal performance, always ensure the target object has a minimum diameter of 10mm.
• If you require a specific temperature range outside the standard options, contact the seller for customizable options between -30°C and 1300°C.
• Consider purchasing optional accessories like intelligent display controllers, cooling shields, various mounts, laser aimers, or sound-light alarms for enhanced functionality and protection in specific environments. These accessories are sold separately.
• Always confirm the required temperature range and output signal before placing an order to ensure the sensor meets your specific needs.
