CTi P7

The Optris CTi P7 pyrometer is specifically designed for non-contact temperature measurement of thin plastic materials, offering a wide range from 0 °C to 710 °C. The infrared sensor specialized spectral region of 7.9 µm ensures precise temperature measurements of thin plastic materials. This innovative pyrometer provides accurate readings within its temperature range and features a measuring head that can withstand temperatures up to 85 °C without additional cooling.

With a measuring wavelength of 7.9 µm, the Optris CTi P7 is particularly well-suited for temperature control during the production of thin plastic foils. The pyrometers machine sensing time of 150 ms ensures rapid response, enhancing efficiency in various industrial processes.

Emissivity, a crucial factor in temperature measurement accuracy, is carefully considered in the design of the Optris CTi P7. Plastics thicker than 0.4 mm and pigmented films can be easily measured in the long-wave IR spectral range (8-14 µm) with high emissivity of ≥ 0.9. However, very thin plastic films are transparent in this spectral range. To address this, the CTi P7 utilizes material-specific absorption bands in the IR spectrum, employing narrowband sensitive IR sensors for precise temperature measurement. For example, materials like Fluoroplastic (FEP), Polyimide (PI), Acrylic (PMMA), Polycarbonate (PC), Polyester (PET), and Polyvinyl chloride (PVC or Vinyl) exhibit IR opaqueness at 7.9 µm and are therefore easy to measure with the Optris CTi P7.

The Optris CTi P7 offers a range of features to meet industrial needs. The infrared thermometers separate electronics box includes easily accessible programming buttons and an illuminated LCD, ensuring user-friendly operation.

The Optris CTi P7 series infrared sensor prioritizes adaptability, featuring an electronics box with a wide array of analog and digital outputs, including 0/4 – 20 mA, 0 – 5 V, 0 – 10 V, thermocouple (type K), built-USB or IP 67 USB interface kit, RS485, RS232 interfaces, relay outputs (2 x optically isolated), Profinet, Ethernet TCP, EtherNet/IP, Modbus TCP, Modbus RTU, IO Link or EtherCAT. To further enhance functionality, optional accessories cater to diverse industrial needs. The mounting fork ensures secure and stable installation for continuous temperature monitoring, while the sighting tube enables precision targeting and improved accuracy in specific applications. The air purge accessory safeguards the temperature sensor from contaminants in harsh environments, and cooling jackets optimize performance in elevated temperature conditions, ensuring consistent and accurate readings. These optional accessories significantly expand the versatility of the Optris CT P7 series, providing tailored solutions for varied industrial scenarios.

Can I shorten the cable between the sensor head and the electronics box?

On the model CTi P7, the sensing head cable can be shortened by max 3m

What distance-to-spot size ratio is correct for the application?

The measuring object’s size and the infrared thermometers optical resolution determine the maximum distance between the sensing head and the measuring object. To prevent measuring errors, the object should fill out the optics field of view. Consequently, the spot should always be at least the same size as the object or should be smaller than that.

How can I improve the noise amplitude of the sensor?

In the CTi models, the head cable must not be moved during the measurement. Use shielded cables only. The sensor shield has to be grounded. Avoid ground loops and related signal interferences in industrial environments. It might be necessary to interrupt the ground connections inside the electronics box. To do this, switch the jumper inside the electronics box to another position. Review the manual.

How do I exchange the sensor head?

From the factory side, the sensing head has already been connected to the electronics and the calibration code has been entered. Any exchange of sensing heads and electronics is possible inside a certain model group. Every head has a specific calibration code, which is printed on the head cable. This calibration code must be stored in the electronic box for correct temperature measurement and sensor functionality.

Can I use the CTi P7 as a 2-wire sensor?

Please do not connect a supply voltage to the analog outputs, as this will destroy the output. The CTi P7 is not a 2-wire sensor. Please review the CSmicro series, as this is a two-wire sensor.
