PID Program Controller Regulus RF and RD

Device image of PID program controller Regulus in panel mount housing and bench top housing.

Regulus RF and RD are specially designed programmable PID controllers for use with a Sensortherm pyrometer and enable intelligent and very fast control processes. They are available in a compact panel-mounting version or a desktop housing for use with two pyrometers and additional relays contacts.

  • Regulus RF: PID program controller for panel mounting
  • Regulus RD: PID program controller as bench top model

Typical application is the process control of nearly all heating processes

  • Inductive soldering
  • Laser soldering
  • Soldering under inert gas
  • Specific preheating and reheating of welding processes


  • Adaptable to nearly every induction system (also for modernizing existing systems with manipulated variable input)
  • Direct output of a continuously adapted 0-10 V manipulated variable for controlling the high-frequency generator or the power component
  • Auto-Tune function for automatic determination of control parameters
  • Additional connection of up to 2 thermocouples possible


Timed heating ramps, holding times and cooling rates are selectively programmable. Intelligent APA (Automatic Process Adaptation) functions improve process control for soldering applications. The extensive logging functions of the SensorTools software are ideal for “online” monitoring and for subsequent analysis of the processes. The controller is able to take full advantage in the high requirements of the laser power control. Applications such as laser hardening, laser soldering or laser welding are no problem due to an extremely fast sampling time of only 100 μs.

  • Extremely fast sampling time of  100 µs
  • 990 program steps within 26 programs
  • Automatic detection of Sensortherm pyrometers
  • Thermocouple input (optional)
  • Measurement range overlap control
  • AutoTune function (automatic P-I determination)
  • Multiple I/O’s: 7 digital outputs and 6 digital inputs
  • Emissivity adjustable for every program step
  • Easy programming via software
  • Also for modernization of existing plants with control input

Additionally at desktop housing model RD

  • Two pyrometers can be connected (e.g. to enlarge the overall temperature range)
  • Up to two thermocouple inputs possible, type S or K
  • 4 limit relays: 230 V, 6 A

SensorTools for Regulus is the standard software to program the Regulus, then the Regulus completely autonomously executes the programmed control steps. Operation with PC connection additionally allows direct visual control of a running process.

  • Controller configuration
  • Creating and saving programs
  • Recording and storing of controlling and temperature processes for documentation purposes
  • Presentation and interpretation of stored events
  • AutoTune function for automatic detection of useful p and i values

Temperature Scanner GALAXY

GALAXY line scanners move the measuring field of a pyrometer continuously over objects and record their temperatures. Several measuring regions can be defined, which can be evaluated separately:

  • The maximum, average and minimum values of each scan of the material to be measured provide a quick overview of the compliance with the required object temperatures.
  • Temperature profiles can be recorded on the PC; they provide information about temperature distributions between the edge and central areas of objects.
  • A surface area display enables the quick visual recording of temperature differences on the material to be measured, similar to the evaluation with thermal imaging cameras.

The scanners can be operated with all pyrometers of the METIS series with RS485 interface. Especially with 2-color pyrometers, surface images with the 2-color measurement technology can be generated; the evaluation with thermal imaging cameras does not provide this possibility.



  • The scanner is equipped with a stepper motor for an extremely long service life and continuous 24-hour operation.
  • 1600 individual steps at a 90 ° measuring angle also enable the recording of up to 1600 individual measured values, so that very detailed evaluations are possible.
  • The stepper motor can also be positioned on each of the 1600 individual steps in order to measure the temperature there.

Models SC71 / SC72 / SC73 / SC75 / SC81 / SC82 / SC83 / SC85

  • up to 16 measuring regions with separate temperature evaluation.
  • Up to 16 analog outputs for separate temperature outputs and stand-alone operation without a PC.
  • Scan angle adjustable between 0.56 and 90°.
  • Adjustable step speed from 1 to 10000 steps/s.
  • Simple setup and measurement data evaluation using the standard SensorTools software or using ASCII commands.

Datasheet: Galaxy SC71 / SC72 / SC73 / SC75 / SC81 / SC82 / SC83 / SC85

Models SC11 / SC12 / SC31 / SC32

Device image temperature scanner type Galaxy
  • up to 4 measuring regions with separate temperature evaluation.
  • Up to 4 analog outputs for separate temperature outputs and stand-alone operation without a PC.
  • Scanning angle adjustable between 3.6 and 90° (SC11 / SC12) or 0.6 and 15° (SC31 / SC22).
  • Adjustable step speed from 1 to 4000 steps/s.
  • Setup and measurement data evaluation via PC or via ASCII commands. With models SC12 and SC32 also directly on the device so that the system can be set on site without a computer.

Built into a cooling housing, the GALAXY can also be used under rough conditions.

Heavy-Duty Measuring System

Optical fiber pyrometer in a heavy industrial housing.

The Pyrometer Measuring System in Heavy Stainless Steel Design is designed for continuous temperature measurement in:

  • Hot strip rolling mills
  • Continuous casting plants
  • Casting machines / automatic casting units
  • Pipe welding machines
  • similarly harsh industrial conditions


Precise measurements under hardest conditions:

  • Use up to 250°C on the measuring head without additional cooling
  • With ratio or radiation pyrometers for 2-color or 1-color IR measurements
  • Extremely resistant stainless steel braided hose
  • Air flushing and air purge of the optics system
  • With high-speed models for measurements at high rolled strip speeds

The system is optimally adapted to the application conditions in the steel industry. The optics system is designed for up to 250°C, the purge air provides additional cooling and keeps the optics tube and thus the pyrometer field of vision free from contamination.
The electronics of the measuring system is mounted in up to 30 meters in a protected position.

  • Flexible application by remotely adjustable emissivity and innovative automatic process adaptation
  • Special pouring stream mode available as an option
  • Customer-specific recalibration possible
  • Highly accurate measurements by latest processor technology and fully digital signal processing
  • Fastest exposure times with smallest spot sizes
  • Using the peak picker allows to detect even smallest scale cracks which represent the “real” temperature to be measured

Application example hot strip rolling mill

Graphic representation of a pyrometer measurement on a reheat furnace exit and roughing stands and a rolling mill.

In this application it is measured by the pyrometer from below of the strip, so that the measurement result is not affected by scale or water puddles on the strip. The evaluation unit is remotely installed in the control cabinet. The measuring tube is kept free from contaminants with flush air.

Device image of the measurement data and maximum value storage type AZ76.

Measurement Data and Maximum Value Storage AZ76

The AZ76 measures the temperatures of passing measuring objects with a pyrometer and determines their maximum temperature. These values the AZ76 compares with a predetermined temperature range and output a corresponding control signal (via 4 switching outputs for the states overheated, too warm, good or too low) if temperatures are in accordance or deviation. Each measured value with valuation result, date and time is stored in the device (max. 32000 records). Data can be read out via interface commands or via the external software SchmiedeWin.



4 signal inputs can be used to transmit switching signals to the AZ76 of successfully changed switching gates to the correct position, and save in the log.

A common use of AZ67 is for the quality assurance and logging in forging that measure a forging blank and control a switch for the reject for non-compliance with the temperature required:

Too hot –> Reject
Too warm –> Reenters the circulation (parameter is optional available)
Good –> Production
Too low –> Can be re-heated and enters the circulation
