1. Introduction

The Logika Technologies Two-Color Handheld Pyrometer, Model PMP-716, is primarily used in

the metallurgical industry to measure the temperature of high speed wire rod, hot rolled steel,

molten metal and slabs/billets. Pyrometers are able to “look” into a process and measure the

target temperature from a distance, thus providing an accurate reading while eliminating

problems associated with contact measurements. Dual wavelength Infrared pyrometers are

able to overcome application challenges such as targets with a small cross-section, variable

emissivity, dust, water or other interfering media between the target and the pyrometer.

Accurate temperatures can be obtained even when the target is 90% obstructed.

The PMP-716 uses a visible laser to assist in aiming and a microprocessor to set up parameters

like emissivity, slope, response time, sampling mode etc. It also has an interior ambient

temperature compensation unit, which allows the instrument to work in temperatures of

0~50°C (32~122°F).

PM-716 is operated by a 9V 6LR61 battery. It also has real time data storage capacity which

can save up to 1000 data points.

2. Description

2.1 Operating Principle

This two-color (colorimetric) infrared pyrometer senses two adjacent infrared wavelengths

emitted by the target using a laminated photosensitive detector. By measuring the infrared

energy emitted from the target, the pyrometer calculates the ratio of these wavelengths to

determine the target temperature.

The primary advantage of Logika’s Two-Color Infrared Pyrometer over thermocouple

temperature measurements is that the pyrometer directly and instantaneously measures the

target temperature rather than inferring it based on the temperature of the atmosphere

surrounding the target.

The advantages of the Logika PMP716 two-color pyrometer vs. a single color pyrometer include:

• Overcomes optical fouling or interfering media between the target and the detector,

such as dust, dirt, smoke, and water vapor to yield accurate temperatures.



P a g e | 3

• Automatically compensates for changes in target emissivity or varying distance from the

target to detector.

• The target does not need to fill the detector’s field of view to accurately measure the

target temperature, allowing flexibility of pyrometer location and target position

variability. An accurate measurement may be made with as little as 10% of the

pyrometer field of view used.

In one-color pyrometer, a single reading is taken and the temperature is derived from the

radiation energy. This works under the following conditions:

• If the emissivity is known and constant

• The object fills the entire field of view

• There is no interference from smoke or dust.

Two color systems measure the ratio of two readings and calculate the temperature from the

ratio rather than the absolute value of readings. This minimizes the effects of emissivity,

optical interference and partial views of the target.

Notes:

• The energy from spectral radiation

increases with higher temperature.

• These curves do not intersect. The

spectral radiation has higher energy

at all wavelengths.

• Each curve has one peak, and these

peaks move towards shorter

wavelengths as the temperature

increases. (Color shift)

• In blackbody radiation, the emitted

energy is only dependent on

absolute temperature.



P a g e | 4

If the object remains at a stable temperature, the ratio of the radiation energy remains constant.

When the target temperature varies, the two wavelength ratio will remain the same. However,

the slope of the ratio change differs when measuring different objects (like metal and

non-metal), so a two-color slope coefficient is needed for correction.

3. Location

3.1 Sensor Location

The Logika PMP-716 Pyrometer should not be used above a heat source for extended periods of

time. Avoid direct exposure to water vapor or excessive dust or smoke

The Logika PMP-716 should be used close enough to the target to allow enough infrared energy

to reach the detector in order to provide a strong signal, but far enough from the target to

minimize the amount of heat that reaches the enclosure’s electronics.

Use Figure 3.1 to determine the PMP-716 Pyrometer’s field of view based on its distance from

the target. Only the intended target should be seen inside the field of view. Other infrared

energy sources such as rolls, other wire or billets could interfere with accurate readings.

Example: The pyrometer measures the temperature of a 5 mm steel wire with adjacent wires

5 mm on each side of the target. Use Figure 3.1 to determine that the pyrometer may be

centered on the target wire and placed up to 1500 mm away from the target wire line (15 mm

total clearance from interference from other target wire lines).



P a g e | 6

Figure 3.1: Pyrometer Distance Graph

3.2 Sensor Aiming

Use the pyrometer’s visible aiming laser to properly align the PMP-716 with the target.

Typically, the pyrometer should be centered on the target. At the same time, adjust the

detection spot by aiming laser to avoid interfering sources of infrared energy, including

reflection of hot metal or sunlight.

3.3 One-Color Mode

One-Color mode can be used to measure the average temperature in an area. The focal range of

the instrument is 0.5m ~ ∞ and the distance can be infinite as long as the measured area is large

enough. When selecting one-color mode, the object should completely cover the visual field;

usually 20% larger than the visual field.

This mode can be used for objects with level surfaces (no bending), with a viewing angle within

30° to the target’s surface. This surface should be physically and chemically stable (not in the

process of oxidation, gasifying or liquefying). The view to the object must also be free of

airborne particles and obstacles. When the background temperature is higher than the

measured temperature, One-Color mode can be used as long as the target fills the entire field of

view.



P a g e | 7

Figure3.2 One Color Mode Temperature Accuracy

3.4 Two-Color Mode

Utilized when:

• Measuring small objects

• Dust, vapor or fog in the environment

• Measuring distance changes

• Part of the object is obscured.

Two-Color temperature measuring mode measures the max temperature in an area regardless

of the size of target. Since the two sampled signals will vary at the same rate, the ratio

between the two signals will not change.

Two-Color mode permits the measurement angle to be smaller than 45°. When the background

temperature is higher than the target temperature, Two-Color mode is not recommended.

Parameter 10 - Upper Alarm: HAL (High Alarm Limit) will be seen on the LCD display if the

temperature reading is higher than the setup value. Default is 1600°C.

Parameter 11 - Lower Alarm: LAL (Low Alarm Limit) will be seen on the LCD display if

the temperature reading is lower than the setup value. Default is 700°C.

Parameter 12 - 2C Energy Reduction: Allowed signal reduction value in two-color mode.

Setting range is 0~95%. When value >95%, it shows “OFF”, and the function is off. Default

is=95%. See chart below.

2C Energy Reduction is a threshold for verifying the validation of the measured temperature.

After the target temperature is calculated by the pyrometer, it calculates each wavelength’s

emissivity at this temperature. For each wavelength, the 2C energy reduction (100% –

Emissivity value) should not be lower than the set value. If either one is higher than the set

value, the LEDs display the lower limit temperature of the pyrometer.

This function is only used in two-color mode. The setup range is 20%-100% and the default

setup value is 95%. If the attenuation ratio is set greater than 95%, this function will shut

down; and again, the lower limit temperature will be displayed. For example, if the pyrometer

is used to detect the temperature of tungsten filament of a light bar, usually the temperature is

higher than 1500°C (2732°F). The tungsten filament (target) diameter is very small at 2mm, so

the emissivity would be very low. According to Figure 5.6, if the temperature is greater than

900°C and target size is 2mm, the 2C energy reduction should be set to 95%. This means that

as long as the emissivity value for each wavelength signal is not less than 5%, the calculated

temperature is valid. In this case, the two-color mode, can still accurately calculate the

temperature. In single color mode, it would be very hard to get an accurate target

temperature in this situation.

The slope is the ratio of the radiant energy from two adjacent wavelengths. Since the radiant

energy of both wavelengths will change in unison with emissivity, the emissivity factor is

eliminated.

Unknown slope: To measure the temperature of other articles or materials, the slope can be set

according to the following steps:

• Use a trusted contact pyrometer or temperature probe to measure the temperature of

the target surface.

• Use average value mode of the pyrometer to measure the temperature on several

locations of the target.

• Adjust the slope of the pyrometer until the reading value equals the temperature of the

measured object.
