Function

The radiation thermometer CellaTemp

PK detects the infrared radiation emit-

ted by an object and converts it into

an electric signal. The detected tem-

perature is displayed and transmittedto the analogue output for further pro-

cessing.

A unique combination of analogue

and digital linearization features

provides the CellaTemp PK with a

high-resolution signal processing unit.

Therefore, even with wide measuring

ranges, the sensor has a very high

temperature resolution while its noise

equivalent temperature difference is

extremely low. The pyrometer thus

supplies stable measurement read-ings even when the response times

are extremely short and the measured

temperatures are very low.

A microprocessor with high clock

speed allows for short response times

starting at 2ms.

The very bright display unit is equipped

with state-of-the-art technology. Even

from a great distance it is easy to read

and it is energy-efcient at the same

time.

Analogue output

The analogue output supplies a signal

linear to the temperature; 0/4 20 mA

are optionally available. The range

setting can be congured with the

control keys.

The analogue output deactivates and

a warning appears on the display

when the internal temperature reach-es 75 C.

LED status switching

Switching output

The presence of a hot object in the

sensors eld of vision triggers a

switching operation when a pre-de-

ned temperature threshold is ex-

ceeded. An LED indicates this switch-ing status.

Optionally, the output can operate as

a normally closed or normally open

contact.

This congurable switch on/switch off

delay allows for a suppression of short

interference pulses and for an ideal

adaptation of the switching output to

the response time of a PLC.

Optical system

The optical system of the CellaTemp

PK is equipped with lenses with an-

ti-reective coatings. This makes the

lenses very durable, easy to clean

and perfectly suitable for rough indus-

trial use.

The excellent imaging characteristics

of the precision lenses provide a high

optical resolution and a minimum sen-

sitivity to stray light. This keeps themeasurement reading stable even

when object sizes and distances

change.

Test funct ion

A functional test of the device and

the signal processing unit can be

performed at any time via an exter-

nal control signal or via the operating

menu.

The analogue output generates an

electric current of 20.5 mA and theswitching function is triggered.

Service function

The service function is used during

setup or running operation to apply

a simulated temperature value that is

displayed and transmitted via the ana-

logue output. This feature checks the

correct functioning and range setting

for the downstream signal processing

units (display, controller, PLC) quicklyand safely even without a hot object.

Diagnostic function

The diagnostic function ensures a

high operational reliability. Incorrect

supply voltages, reverse polarities of

connections, overloads at the switch-

ing output, unacceptable ambient

temperatures or out-of-range object

temperatures appear on the displayas error messages.

Laser module

During setup of the CellaTemp PKF

26/36 the laser module PS 01/P is

mounted to the end of the bre optic

cable to adjust the sensors focussing

range and to perform an alignment to

the target.
