T-GAGE M18T Series Infrared Temperature Sensors

Overview

The T-GAGE analog sensor is a passive, non-contacting, temperature-based de­vice. It is used to detect object(s) temperature within a sensing window and out­put a proportional voltage or current.
While it looks and operates just like an Expert photoelectric sensor, the T­GAGE detects the infrared light energy emitted by objects, instead of its own emitted light. The sensor uses a thermopile detector, made up of multiple infra­red-sensitive elements (thermocouples) to detect this infrared energy within its field of view (see Figure 2. Detection spot size versus distance from sensor on page 2).
Potential applications include:
• Hot part detection (baked goods, metals, bottles, rubber)
• Ejection verification of injection-molded parts
• Flame process verification
• Hot glue detection (packaging equipment, book binding, product assembly)
• Cold part detection (frozen foods, ice, dairy)
• Roller monitoring

Sensing Field of View

The sensing range is determined by the sensor’s field of view (FOV), or viewing angle, combined with the size of the object(s) being detected (see Figure 2. Detection spot size versus distance from sensor on page 2). The sensor’s distance-to- spot size ratio (D:S ratio) is inversely related to the viewing angle; a sensor with a small viewing angle will have a large D:S ratio. The T-GAGE M18T sen­sors have D:S ratios of 6:1, 8:1 or 14:1. For a sensor with an 8:1 D:S ratio, the sensor’s spot size is a 1" diameter circle at a distance of 8"; farther from the sensor face the spot size will be larger.

Apparent Temperature

Two factors that have a large influence on apparent temperature are the object’s emissivity and whether or not the object fills the sensor’s field of view.
Object Emissivity:
A “blackbody” is a “perfect” emitter, with an emissivity of 1.0 at all temperatures and wavelengths. Most surfaces emit only a fraction of the amount of thermal energy that a blackbody would. Typical T-GAGE applications will be sensing objects with emissivities ranging from 0.5 to 0.95. Many references are available with tables of emissivity coefficients for common materi­als. In general, shiny unpainted metals have low emissivity, while non-glossy surfaces have high emissivity.
Shiny surfaces: a mirror or shiny surface can redirect an object’s emitted energy to an undesired location, or even bring additional unintended thermal energy into the sensor’s field of view (see Application Note on page 6).
Object Size:
If the object being detected does not fill the sensor’s field of view, then the sensor will average the temperature of that object and whatever else is in the sensing field of view. For the sensor to collect the maximum amount of energy, the object should completely fill the sensor’s field of view. However, in some applications, when the object is too small, this may not be possi­ble. In such cases, if the object is hot enough, the thermal contrast may still be adequate to trigger the sensor’s output.

Alarm Output

The alarm output will activate when the analog output is at 10V or 20mA, depending on model (see Figure 3. Analog/Alarm outputs as a
function of taught conditions on page 3).

Analog Output

The T-GAGE analog sensor can be programmed for either positive or negative output slope, based on the teach order (see Figure 3. Analog/
Alarm outputs as a function of taught conditions on page 3). If the cold
limit is taught first, the slope will be positive; if the hot limit is taught first, the slope will be negative. Banner’s scalable output automatically distrib­utes the output signal over the width of the programmed sensing window.

conditions

Sensor Programming

Two TEACH methods may be used to program the sensor:
• Teach individual minimum and maximum limits (Two-Point Static Teach), or
• Dynamic Teach for on-the-fly programming.
The sensor may be programmed either via its push button, or via a remote switch. Remote programming also may be used to disable the push button, preventing unauthorized personnel from adjusting the programming settings. To access this feature, connect a normally open switch between the sensor’s gray wire and dc common or connect the gray wire to a digital input (PLC).
Programming is accomplished by following the sequence of input pulses (see Teaching Limits Using Two-Point Static TEACH on page
4). The duration of each pulse (corresponding to a push button “click”), and the period between multiple pulses, are defined as “T”:
