1. Safety Instructions
This document contains important information, which should be kept at all times with the
instrument during its operational life. Other users of this instrument should be given these
instructions with the instrument. Eventual updates to this information must be added to the
original document. The instrument can only be operated by trained personnel in accordance
with these instructions and local safety regulations.
Acceptable Operation
This instrument is intended only for the measurement of temperature. The instrument is
appropriate for continuous use. The instrument operates reliably in demanding conditions, such
as in high environmental temperatures, as long as the documented technical specifications for
all instrument components are adhered to. Compliance with the operating instructions is
necessary to ensure the expected results.
Unacceptable Operation
The instrument should not be used for medical diagnosis.
Replacement Parts and Accessories
Use only original parts and accessories approved by the manufacturer. The use of other
products can compromise the operation safety and functionality of the instrument.
Instrument Disposal
Disposal of old instruments should be handled according to professional and
environmental regulations as electronic waste.
Operating Instructions
The following symbols are used to highlight essential safety information in the operation
instructions:
Helpful information regarding the optimal use of the instrument.
Warnings concerning operation to avoid instrument damage and personal injury.
The instrument can be equipped with a Class 2 laser. Class 2 lasers shine only
within the visible spectrum at an intensity of 1 mW. Looking directly into the laser
beam can produce a slight, temporary blinding effect, but does not result in physical
injury or damage to the eyes, even when the beam is magnified by optical aids. At
any rate, closing the eye lids is encouraged when eye contact is made with the laser
beam. Pay attention to possible reflections of the laser beam. The laser functions
only to locate and mark surface measurement targets. Do not aim the laser at
people or animals.
Pay particular attention to the following safety instructions.
Use in 115/230 V~ electrical systems can result in electrical hazards and personal
injury, if not properly protected. All instrument parts supplied by electricity must be
covered to prevent physical contact and other hazards at all times.

Description
Theory of Operation for Ratio (2-Color) Sensors

2. Description
These Endurance series pyrometers with an integrated sensor head are infrared noncontact
temperature measurement systems. Such devices have an adjustable focus, a through-the-
lens sighting capability, and a parallax-free optical axis. Theyare energy transducers, designed
to measure accurately and repeatedly the amount of heat energy emitted from an object, and
then convert that energy into a measurable electrical signal. Each model operates as an
integrated temperature measurement subsystem consisting of optical elements, spectral filters,
detectors, digital electronics and an IP65 (NEMA-4) rated housing. Each is built to operate on
a 100 percent duty cycle in industrial environments. Various output types are offered for easy
integration into industrial monitoring and control environments.
Endurance series pyrometers are available for different kind of temperature measurement
applications and are separated into the following variants:

Model
Description
E1ML, E1MH
-Monochrome (1-Color)-
1C-sensor in spectral range of 1.0 µm for different
temperature ranges
E2ML, E2MM, E2MH
-Monochrome (1-Color)-
1-C-sensor in spectral range of 1.6 µm for different
temperature ranges
E3ML, E3MH
-Monochrome (1-Color)-
1-C-sensor in spectral range of 2.4 µm for different
temperature ranges
E1RL, E1RH
-Ratio (2-Color)-
2-C-sensor in spectral range of 1.0 µm (nominal) for
different temperature ranges
E2RL
-Ratio (2-Color)-
2-Color-sensor in spectral range of 1.6 µm (nominal)
for different temperature ranges
Monochrome (1-Color mode) types for standard temperature measurement applications
The 1-Color mode is best for measuring the temperature of targets in areas where no sighting
obstructions, either solid or gaseous, exist. Such 1-Color mode is also best where the target
completely fills the measurement spot.
Ratio (2-Color mode) types for specific temperature measurement applications
Such pyrometers determine the object temperature by the ratio of two separate and overlapping
infrared bands. The 2-Color mode is best for measuring the temperature of targets that are
partially obscured, either intermittently or permanently by other objects, openings, screens, or
viewing windows that reduce energy, and by dirt, smoke, or steam in the atmosphere. The 2-
Color mode can also be used on targets that do not completely fill the measurement spot,
provided the background is much cooler than the target. Ratio pyrometer types are able to
measure and determine the object temperature in either one of both modes (1-Color / 2-Color),
in which always 2 infrared sensors are active.

which don’t depend on absolute radiated energy values. In use, a 2-Color sensor determines
temperature from the ratio of the radiated energies in two separate wavelength bands (colors).
The benefits of 2-Color sensors are that accurate measurements can be made under the
following conditions:
•When the field of view to the target is partially blocked or obscured.
•When the target is smaller than the sensor’s field of view.
•When the target emissivity is low or changing by the same factor in both wavelength
bands.
Another benefit is that 2-Color sensors measure closer to the highest temperature within the
measured spot (spatial peak picking) instead of an average temperature. A 2-Color sensor can
be mounted farther away, even if the target does not fill the resulting spot size. The convenience
is that you are not forced to install the sensor at some specific distance based upon target size
and the sensor’s optical resolution.
2.1.1. Partially Obscured Targets
The radiated energy from a target is, in most cases, equally reduced when objects or
atmospheric materials block some portion of the optical field of view. It follows that the ratio of
the energies is unaffected, and thus the measured temperatures remain accurate. A 2-Color
sensor is better than a 1-Color sensor in the following conditions:
•Sighting paths are partially blocked (either intermittently or permanently).
•Dirt, smoke, or steam is in the atmosphere between the sensor and target.
•Measurements are made through items or areas that reduce emitted energy, such as
grills, screens, small openings, or channels.
•Measurements are made through a viewing window that has unpredictable and
changing infrared transmission due to accumulating dirt and/or moisture on the window
surface.
•The sensor itself is subject to dirt and/or moisture accumulating on the lens surface.
1-Color sensors see polluted atmosphere and dirty windows and lenses as
a reduction in energy and give much lower than actual temperature
readings!
2.1.2. Targets Smaller Than Field of View
When a target is not large enough to fill the field of view, or if the target is moving within the
field of view, radiated energies are equally reduced, but the ratio of the energies is unaffected
and measured temperatures remain accurate. This remains true as long as the background
temperature is much lower than the target’s. The following examples show where 2-Color
sensors can be used when targets are smaller than the field of view:
•Measuring wire or rod —often too narrow for field of view or moving or vibrating
unpredictably. It is much easier to obtain accurate results because sighting is less
critical with two-color sensors.
•Measuring molten glass streams —often narrow and difficult to sight consistently with
single-wavelength sensors.
2.1.3. Emissivity and 1-Color (single wavelength) measurements
Emissivity is a calculated ratio of infrared energy emitted by an object to the energy emitted by
a blackbody at the same temperature (a perfect radiator has an emissivity of 1.00). The
emissivity is preset at 1.00. For information on determining an unknown emissivity, and for
sample emissivities, refer to the appendix of this manual.

When target emissivity is uncertain or changing, a 2-Color sensor can be more accurate than
a 1-Color instrument as long as the emissivity changes by the same factor in both wavelength
bands. Accurate measurement results are dependent on the application and the type of
material being measured. The emissivity of all real objects changes with wavelength and
temperature, at varying degrees, depending on the material. To determine how to use 2-Color
sensors with your application when uncertain or changing emissivities are a factor, please
contact our sales representative or technical support department.
2.1.4. Slope (2-Color ratio) measurements
The slope is the quotient of the emissivities based on the narrow and the wide spectral range
(first and second wavelength). The factory default preset slope is 1.000.
For information on determining an unknown slope, and for sample slopes, refer to the appendix
of this manual.
The slope is the important parameter for measurements in 2-Color mode!
The emissivity affects only measurements in 1-Color mode.
Experts figured out, that extreme dirt (dust, fingerprints) on the optical lens
or vision window influences the Endurance 2-Color measurement chain.
Unpredictable temperature readings may result in such a case!

Analog Output (current loop, 0/4 –20mA)
Galvanically isolated analog output signal, to stimulate output currents (0/4 - 20 mA). The
output signal is an active output with 16 Bit resolution, to drive a maximum resistive load of
500Ω. Just the acquired object temperature, measured by either 1C or 2C devices and
displayed on on the rear Endurance operators display, is converted to a 16 Bit current
equivalent. The user has to define the temperature measurement range and must assign
the lower and upper range limits to the current equivalent (0 –20mA / 4 –20mA).
The following formula demonstrates the output current (Ic) calculation regarding the given
measurement span [upper temperature(TU) –lower temperature(TL)].
Given example values:
•Upper meas. Temp. (Tu): 2000°C, Lower meas. Temp.(TL): 1000°C
•Choosen output current range: 4 –20mA, ICL = 4mA at TLICU = 20mA at TU
•Actual meas. Temp.: Tmeas = 1578°C
Ic = Icl + Icu − Icl
Tu −Tl ∗(Tmeas − Tl)= 4mA + 20mA − 4mA 2000°C − 1000°C ∗(1578°C − 1000°C)=13.248mA
