Temperatures up to 4,000 °C
With the high-temperature models KTRD 1085 and KTRD 1485, our pyrometers cover measurement tasks that go beyond the upper limits of many conventional industrial series.
Extreme temperatureWe offer a compact, logically structured portfolio of pyrometers with a high degree of technical adaptability. Our particular strength lies not in offering as many product names as possible, but in the precise configuration of the measurement range, wavelength, optics, response time, fiber optic cable, and interface for the specific system.
The result: robust industrial temperature measurement for metal, induction, hardening, forging, rolling, casting, and rapid thermal processes—from compact sensors to standalone PID control systems.
A pyrometer detects the infrared radiation emitted by an object and converts it, step by step, into a temperature signal that can be analyzed. This allows the temperature of a target to be measured quickly and without contact.
There are various technical approaches to this conversion—so-called conversion chains. Which chain is optimal depends, among other things, on the required measurement accuracy, the measurement speed, the available installation space, the environment, the costs, and the specific measurement task.
The specific design of a pyrometer is therefore always a combination of optics, spectral range, detector, signal processing, and data analysis. The optimal solution results from the process requirements and the appropriate technical implementation.
Our pyrometers are particularly useful when high speed, challenging installation conditions, standard machine communication, or custom configurations are more important than having the widest possible standard product line.

Extreme temperatureThe KTRD-HS family makes rapid temperature changes easily manageable. This is crucial for induction, wires, rotating parts, and short heating cycles.
Dynamic Processes0/4–20 mA, RS232, RS485, and optional solutions with PROFIBUS, PROFINET, Ethernet, EtherCAT, or USB simplify new installations, retrofits, and integration into existing control systems.
PLC & FieldbusThe focusable optics allow adjustment to the measurement distance and measurement spot. The green LED aiming light facilitates visible and reproducible alignment with the actual measurement point.
Align SafelyThe 14xx and 44xx series separate the electronics from the measurement point. This is ideal for high ambient temperatures, electromagnetic fields, tight installation spaces, or hard-to-reach processes.
Challenging EnvironmentWith the AED evaluation electronics, the pyrometer can be turned into a complete control system featuring a touchscreen display, data storage, a PID controller, autotuning, and programs.
Process ControlOur product families follow a clear classification system. This allows the selection of equipment to be based on the installation situation and the process requirements.
The universal KTRD models are suitable for demanding stationary measurement tasks, featuring focusable optics, a targeting aid, various wavelengths, and a wide range of interfaces.
These compact devices are designed for direct machine integration . They combine small dimensions with fast response times and spectral ranges suitable for metal detection.
Ratio pyrometers evaluate the ratio of two spectral regions. This allows them to operate more reliably than single-color devices in the presence of smoke, dust, dirty viewing windows, or partially obscured measurement targets.
During very short warm-up phases, a slow device may smooth out temperature spikes or miss them entirely. The HS Series is clearly positioned for dynamic measurement tasks.
Fiber-optic cables and attachment optics bring optical measurement to the process site, while the sensitive electronics can be mounted at a safe distance.
Our portfolio complements the sensors with practical system components. The scanner expands the capabilities of a universal pyrometer for line measurement; the AED handles display, data storage, interfaces, and control.
Its particular strength stems from the interplay of spectral selection, optics, signal processing, and system communication.
The material, temperature, and surface determine which spectral range is technically appropriate.
Vario optics, measuring distance, measuring spot, target light, or fiber optic cable are adapted to the actual installation conditions.
The standard or high-speed version is selected based on process time, component speed, and control task.
Analog output, serial interface, fieldbus, or AED control connect the measurement to the machine and the process.
The following applications benefit particularly from the combination of fast response times, wavelengths suitable for metal detection, fiber optics, flexible interfaces, and optional control technology.
Rapid heating, strong electromagnetic fields, and limited space make high-speed and fiber-optic solutions particularly valuable.
Reproducible temperature measurement enables better process control, consistent component quality, and less scrap.
High temperatures, smoke, and partially obstructed viewing areas call for short-wavelength or two-color devices, depending on the process.
Small, moving, or difficult-to-track measurement objects require rapid acquisition, appropriate optics, and, in some cases, a scanning motion.
Rugged, stationary measurement and flexible interfaces facilitate integration into existing machines and process control systems.
Traditional analog and serial signals, as well as optional fieldbuses, are particularly useful when integrating new sensors into older systems.
Our pyrometers are particularly effective when the goal is not just to display a temperature, but to tailor a measurement solution precisely to the process, environment, and control system .
When making a selection, the material, surface, temperature range, measuring distance, measuring spot, process speed, environment, and desired interface should always be considered together.

This allows us to equip both new machines and existing systems with the appropriate technology.
That depends on the metal, temperature, surface, and process. For hot metals, short-wavelength devices such as models from the KTRD 1xxx, 4xxx, or fiber-optic families are often a good choice. In the presence of smoke, dust, or partial shading, the QKTRD may offer advantages.
When the temperature changes in a matter of milliseconds or the object being measured is in the measurement field for only a very short time. Typical examples include induction heating, wires, rapidly moving parts, short soldering cycles, or localized hardening processes.
In cases of high ambient temperatures, strong electromagnetic fields, confined installation spaces, or hard-to-reach measurement points. The optical components remain in contact with the process, while the electronics are mounted at a safe distance.
No. In addition, the wavelength, emissivity, surface condition, measurement spot, measurement distance, viewing conditions, response time, and interface must be checked. Spectral selection is particularly important for bare or oxide-free metals.
Please provide us with the material, temperature range, surface, measurement distance, measurement spot, desired response time, and existing control system. We will determine the appropriate wavelength, optics, device family, and interface for your application.
