Non-contact Infrared Temperature Sensor
ST03 non-contact infrared sensors measure temperature from 0°C to 1200°C and provide a linear 4 to 20mA output. This output signal is compatible with almost any indicator, controller, recorder, data logger ect., without the need for special interfacing or signal conditioning. They are suitable for most materials such as food, paper, textiles, plastics, leather, tobacco, pharmaceuticals, chemicals, rubber, coal and asphalt; but mot materials with low emissivity, for example polished metals. Two-wire CS20L4sensorstransmit thetarget temperatureasa 4-20mA output and offer a simple solution for most applications.

A range of accessories to suit different applications and industrial environments is available. These may be ordered at any time. The accessories consist of the following parts. Fixed mounting bracket Adjustable mounting bracket Air purge collar Laser sighting tool
The optical chart below indicates the nominal target spot diameter at any given distance from the sensing head and assumes 90% energy.
The installation process consists of the following stages: Preparation Mechanical installation Electrical installation Please read the following sections thoroughly before proceeding with the installation.
Ensure that the sensor is positioned so that it is focused on the target only.
Distance and spot size
The size of the area (spot size) to be measured determines the distance between the sensor and the target. The spot size must not be larger than the target. The sensor should be mounted so that the measured spot size is smaller than the target.
The sensor is designed to operate in ambient temperatures from 0°C to 60°C. For ambient temperatures above 60°C, an air/water-cooled housing will be required. Avoid thermal shock. Allow 20 minutes for the unit to adjust to large changes in ambient temperature.
Smoke,fumes or dust can contaminate the lens and cause errors in temperature measurement. In these types of environment the air purge collar should be used to help keep the lens clean.
To minimize electromagnetic interference or ‘noise’, the sensor should be mounted away from motors, generators and such like.
Checking the distance between the sensor and the indicating/controlling device. If necessary, the CS20L4 sensor can be ordered with a longer cable attached.
Models with thermocouple output
When extending the cable, ensure thermocouple extension cable and connectors are used.
Be sure to use a 5~30V DC (>25mA) power supply.
All sensors come with a 1.5m cable and a mounting nut. The sensor can be mounted on brackets or cut outs of your own design, or you can use the fixed and adjustable mounting bracket accessories.
Once the sensor is in position and the appropriate power, air, water, and cable connections are secure, the system is ready for continuous operation by completing the following simple steps:
1. Turn on the power supply
2. Turn on the meter, chart recorder or controller
3. Read/monitor the temperature.
