The INFRAsmart R 300/301/302
family comprises stationary pyrometers for contactless measurement of temperature.
This technique is a big advantage,
for example, if the object to be
measured moves or is live. The
contactless measuring principle
also makes sense if the measured
object is a poor conductor of heat
(e.g. plastic films, paper or bulk
materials) or if the measurement
has to be completed quickly.
This results in a very broad range
of applications, such as:
Thermoforming machines for plastics,
Extruders for plastics,
Calendaring lines for plastic films,
Coating machines,
Glassworking,
Metalworking,
Supervision of products on conveyor belts,
Monitoring of plant overheating, etc.

With the R 301 and R 302 types,
the infrared radiation is focused on
the sensing element by a lens. The
R 300 type works with a high-gloss,
gold-plated cone.

Measuring ranges:
0...2000 °C in sub-ranges

Measurement signal:
4...20 mA, linear

The pyrometers are extremely
compact, with integrated electronic
components that convert the measurement signal to 4...20 mA.

Power supply:
12...30 V DC

Smallest measuring field:
5 mm

Vibration-proof, no moving
parts

Interface: HART® protocol

Cooling systems are available for
operation at ambient temperatures
higher than 70 C.
An air purging nozzle can be supplied for dusty or damp environments to keep the lens or the cone
clean.
