Overview
The T-GAGE analog sensor is a passive, non-contacting, temperature-based device. It is used to detect objects that are either hotter
or colder than the ambient condition and then activate an output.
Although it looks and operates just like an Expert™ photoelectric sensor, the T-GAGE 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 Sensing Field of View on p. 2).

1 To order the 9 m (30 ft) PVC cable model, add the suffix "W/30" to the cabled model number. For example, M18TB8 W/30. Models with a quick disconnect
require a mating cordset.

Sensing Field of View

Sensing range is determined by the sensor’s field of view or viewing angle, combined with the size of the object(s) being detected.
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
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 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 p. 7.
Object Size
If the object being detected does not fill the sensor field of view, then the sensor averages 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 field of view. 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 output.

Installation

Installation Note
Align the sensor toward the object to be detected. Visually align if possible, or use the alignment device accessory listed in
Additional Accessories on p. 8.

Sensor Configuration
Configure the sensor using one of two TEACH methods:
• Two-Point Static TEACH
• Dynamic TEACH
Use the push button or remote input to configure the sensor.

Note: The duration of each remote line pulse (corresponding to a push button “click”), and the period between
multiple pulses, are defined as “T”: 0.04 seconds < T < 0.8 seconds.

Push Button Enable/Disable

The push button can be disabled using the remote input wire (gray) to prevent unauthorized adjustment. To disable the push button,
connect a normally open switch between the remote input wire and dc common or connect the remote input wire to a digital output
on a Programable Logic Controller (PLC). Perform the procedure below to enable or disable the push button, where 0.04 s < T < 0.8
s.

2-Point Static TEACH

Use 2-Point Static TEACH configuration method for applications where both ON and OFF target conditions can be presented to the
sensor statically by the operator. The sensor establishes a single sensing threshold (the switchpoint) midway between the two
configured conditions, with the Output ON condition on one side and the Output OFF condition on the other.

Note: The sensor returns to RUN mode if the first 2-Point Static TEACH condition is not configured within 60
seconds.

Note: After the first condition is configured, the sensor remains in 2-Point Static TEACH configuration until the
second condition is configured.

configuration.

Dynamic TEACH
Use Dynamic TEACH configuration method for applications where both the ON and OFF target conditions can not be presented to
the sensor dynamically by the operator. After the configuration has been completed, the threshold at the midpoint is optimized by the
sensor halfway between the average signals presented during the Dynamic TEACH configuration.
