Flashing red
The sensor is in TEACH mode and is waiting for the second limit
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.

Analog Output Slope
The U-GAGE S18U sensor may be programmed for either a positive or a negative output slope, based on which limit is taught first.
If the Near limit is taught first, the slope will be positive. If the Far 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.
In the event of signal loss, the analog output goes to 3.6 mA or 0 V dc, which may be used to trigger an alarm.

Installation
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:
4 0.04 s < “click” < 0.8 s
5 0.04 s < T < 0.8 s

U-GAGE™ S18U Series Sensors with Analog Output
In metric units:
In English units:
Cm/s = 20 √273 + TC
Cft/s = 49 √460 + TF
Cm/s = speed of sound in meters per second
Cft/s = speed of sound in feet per second
TC = temperature in °C
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.

Linearity 6
2.5 ms response: ±1 mm
30 ms response: ± 0.5 mm
Output Ratings
Analog Voltage Output:
2.5 kΩ minimum load resistance
Minimum supply for a full 10V output is 12V DC (for supply voltages
between 10 and 12, V out max is at least V supply -2)
Analog Current Output:
1 kΩ max @ 24V input
Max load resistance = (Vcc-4)/0.02 ohms
For current output (4-20 mA) models, ideal results are achieved when the
total load resistance R = [(Vin – 3)/0.020] Ω. Example, at Vin = 24 V DC, R ≈
1 kΩ (1 watt). A worst-case shift of 1% of sensing distance is caused by
operating the sensor at Vin = 30 V DC and R = 0 Ω.
