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.

absolute temperature.
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.
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
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.

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).

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.

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 7 - Real Time Display Interval: The internal sample time is 0.1s. The setup range for the real time display is from 0.1 to 1.0s. If set to 1.0s, the displayed value is the average over the last ten readings (0.1s each).
Parameter 8 - Power Off Time: Default power off time is 10 minutes.
Parameter 9 - Light On/Off: LCD Backlight ON/OFF. Setup takes effect after the power is
OFF/ON.
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.

6.4 Two-Color Slope Coefficient
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.
The following slopes are approximations and will vary with the alloy material and surface finish:
For measuring the following oxidized surface metal materials, the slope is approximately 1.0.
Cobalt Stainless steel Nickel Iron Steel
For measuring the following metal materials with smooth, clean and non-oxidized surface, the slope is approximately 1.03.
Cobalt Stainless Steel Nickel Rhodium Cast Iron Tungsten Molybdenum Steel Tantalum Platinum

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.
7. Maintenance
7.1 Regular Maintenance
Regular attention to the following will ensure steady operation of the sensor: Lens Cleaning- Routinely check the PMP-716 lens glass for dust or oil residue. When necessary,
clean the glass with alcohol and lens paper or soft cloth. Calibration- Occasional calibration (see Section 5.4) will ensure that the accuracy of the PMP-716 Pyrometer is maintained.
