Thermophil ® INFRAht R 310 / R 311 / R 312 / R 320

Contactless measurement of
temperature at high ambient
temperatures.

Sturdy and tight stainless
steel housings to IP 64.

Two-wire 4-20 mA technique
in combination with TR 40 /
TR 41 transmitter.

Sensor heads uncooled up to
125 C ambient temperature.

The pyrometers are extremely compact and connected to the transmitter
by a teflon cable.
Cooling systems are available for
ambient temperatures higher than
125 C.
An air purging nozzle can be supplied
for dusty or damp environments to
keep the lens or the cone clean.

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 or
paper) or if the measurement has to
be completed quickly.

Measuring ranges: 0...2000 C

The INFRAht R 310/311/312/320 family
comprises stationary pyrometers with
a remote transmitter for contactless
measurement of temperature.

Temperature monitoring with
ignition protection standard IPL
1, TÜV certificate no. 71332449

Fixing brackets and other accessories
are also available.
The INFRA TR 40 and TR 41 transmitters integrate the evaluation electronics for the INFRA sensor heads in
the INFRAht family (R310/311/312/320).
They feature an analogue two-wire
interface (4…20 mA).
Communication is controlled by a
HART® protocol.
The transmitters can be used at ambient temperatures up to 70 °C.

This results in a very broad range of
applications, such as:
Thermoforming machines for plastics,
Extruders for plastics,
Calandering lines for plastic films,
Coating machines,
Glassworking,
Metalworking,
Supervision of products on conveyor belts,
Monitoring of plant overheating, etc.

The TR 40 transmitter is accommodated in sturdy die-cast aluminium
housing and has no operator controls
or displays.

With the R 311 and R 312 types, the
infrared radiation is focused on the
sensing element by a lens. The R 310
and R 320 types work with a highgloss, gold-plated cone.

The TR 41 transmitter is supplied in a
plastic housing. It includes an LC
display and a configuration keyboard.
