WARNING: Not To Be Used for Personnel Protection
Never use this device as a sensing device for personnel protection. Doing so could lead to serious injury or
death. This device 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.

Sensor Programming
Use one of two TEACH methods to program the sensor:
•
•
Teach individual minimum and maximum limits
Use Auto-Window feature to center a sensing window around the taught position
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 the gray wire of
the sensor to 0 V dc to 2 V dc, with a remote programming switch between the sensor and the voltage.
NOTE: The impedance of the Remote Teach input is 12 kΩ.
Programming is accomplished by following the sequence of input pulses. 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.

Normally Open/Normally Closed Operation Select
The sensor can be configured for either normally open or normally closed operation via the remote teach wire (gray). A series of three
pulses on the line will toggle between normally open and normally closed operation. Normally open is defined as the output energizing when
the target is present. Normally closed is defined as the output energizing when the target is absent. See Figure 2 on page 2 and Figure 3 on
page 3.

Principles of Operation
Ultrasonic sensors emit one or multiple pulses of ultrasonic energy, which travel through the air at the speed of sound. A portion of this
energy reflects off the target and travels back to the sensor. The sensor measures the total time required for the energy to reach the target
and return to the sensor. The distance to the object is then calculated using the following formula: D = ct ÷ 2
D = distance from the sensor to the target
c = speed of sound in air
t = transit time for the ultrasonic pulse
To improve accuracy, an ultrasonic sensor may average the results of several pulses before outputting a new value.
Temperature Effects
The speed of sound is dependent upon the composition, pressure and temperature of the gas in which it is traveling. For most ultrasonic
applications, the composition and pressure of the gas are relatively fixed, while the temperature may fluctuate.
In air, the speed of sound varies with temperature according to the following approximation:

U-GAGE S18U Series Sensors with Discrete Output
Cm/s = speed of sound in meters per second
TC = temperature in °C
Cft/s = speed of sound in feet per second
TF = temperature in °F
Temperature Compensation
Changes in air temperature affect the speed of sound, which in turn affects the distance reading measured by the sensor. An increase in air
temperature shifts both sensing window limits closer to the sensor. Conversely, a decrease in air temperature shifts both limits farther away
from the sensor. This shift is approximately 3.5% of the limit distance for a 20° C change in temperature.
The S18U series ultrasonic sensors are temperature compensated. This reduces the error due to temperature by about 90%. The sensor will
maintain its window limits to within 1.8% over the -20° to +60° C (−4° to +140° F) range.
NOTE:
•
Exposure to direct sunlight can affect the sensor’s ability to accurately compensate for changes in
temperature.
•
•
If the sensor is measuring across a temperature gradient, the compensation will be less effective.
The temperature warmup drift upon power-up is less than 1.7% of the sensing distance.After 10 minutes, the
apparent distance will be within 0.3% of the actual position. After 25 minutes, the sensing position will be
stable.
