working principle

CTi LT measures the surface temperature of the object being measured using infrared radiation in the 8-14 μ m wavelength range. The probe collects the signal and transmits it to an electronic box for amplification and digital processing; Users can set emissivity/transmittance (0.05-1.10) and hold/average algorithms, and output them to the upper system as analog or bus signals to achieve continuous, non-contact online temperature measurement.

Opus fixed infrared temperature sensor (two-piece)application field

Suitable for online temperature measurement of high emissivity materials in automated production lines, such as paper, plastic, textiles, wood, food packaging, non reflective sections in glass/metal processes, etc; The small probe, long cable, and high ambient temperature capability make it suitable for fixed installation in narrow spaces near heat sources.

Selection Recommendation

Select optical/range according to the temperature measurement area: It is generally recommended to use LT02 (≤ 650 ° C)/LT15 (≤ 800 ° C)/LT22 (≤ 1050 ° C).

Select SF/CF optics based on installation distance and target size; When dealing with small targets at close range, use CF (including a close-up mirror) to obtain smaller light spots.

If the ambient temperature is high and the space is limited, use a split structure measuring head and confirm whether additional protection is needed on site; If the environment is hotter, consider LThot derivatives.

Interface and system integration: For scenarios requiring PLC/industrial Ethernet, select Profinet/EtherNet IP/Modbus versions.

Installation and precautions

Align the target based on the distance to spot ratio to ensure that the spot falls within the measured surface.

Set emissivity/transmittance and calibrate when measuring semi transparent materials or with windows.

Avoid strong reflection and direct smoke on the measuring head, and if necessary, provide shading/blowing.

Confirm the environmental temperature and protection level (IP65), select appropriate cable length and stress fixation for wiring.

Before powering on, check the polarity of the analog/digital output and power supply to prevent misconnection.

maintenance

Regularly clean the probe window and keep the optical path clean; Do not wipe with hard objects.

Inspect cables and connectors for looseness/wear, and maintain good sealing (IP65).

When there is a process change, review the emissivity/signal processing parameters and recalibrate them.
