  WARNING: Not To Be Used for Personnel Protection
  Never use this product as a sensing device for personnel protection. Doing so could lead to serious injury or death. This product does NOT include the self- checking redundant circuitry necessary to allow its use in personnel safety applications. A sensor failure or malfunction can cause either an energized or de-energized sensor output condition.

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

NOTE: The T-GAGE M18T sensor is not intended for absolute temperature measurement or for safety-related fire detection use.
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.  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).
NOTE: The impedance of the Remote Teach input is 3 kΩ.
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”:
0.04 seconds < T < 0.8 seconds

**Status Indicators

**

TEACH Mode: Waiting for Span condition
ON Yellow| Run Mode: Alarm output is energized
TEACH Mode: Waiting for Null condition
Flashing Yellow| Dynamic TEACH active

Teaching Limits Using Two-Point Static TEACH
Two-Point TEACH is the traditional setup method, used when two conditions can be presented individually by the user. The sensor establishes the Null (0V or 4mA) output condition with the first taught condition and the Span (10V or 20mA) output condition with the second taught condition, and it scales between these points.
General Notes on Programming

• The sensor will return to RUN mode if the first TEACH condition is not registered within 60 seconds
• After the first limit is taught, the sensor will remain in PROGRAM mode until the TEACH sequence is finished

Sensor returns to beginning of Teach
Exit Without Save| •  Push and hold push button for 2 seconds| • Hold remote line low for 2 sec- onds 2 seconds| Sensor returns to Run mode without sav- ing new settings

Teaching Limits Using Dynamic TEACH
Dynamic TEACH is a method of setting the sensor’s limits while the application is active. Dynamic TEACH will sense the high and low temperature limits of the process and automatically set the analog range between these limits.
The output slope will remain in the direction of the most recently taught Two- Point Static TEACH or default to positive.
