Ultrasonic sensors emit a series of ultrasonic energy pulses, which travel through the air at the speed of
sound. A portion of this energy is reflected by 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:

To improve accuracy, an ultrasonic sensor elaborates the average results of several pulses before
activating the output.

Temperature effects

The speed of sound depends on the composition, pressure and temperature of the gas in which it is
travelling. For most ultrasonic applications, the composition and pressure of the gas a re rela tively f ixed,
while the temperature may vary.
In air, the speed of sound varies according to the following approximate formulas:

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. Viceversa, 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 US30 ultrasonic sensors are temperature compensated. This reduces the error due to temperature
by about 90%. The sensor will maintain its window limits to within 2.2% over the -40° to +70°C range.

Notes:

- 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.

SENSOR PROGRAMMING

Two TEACH methods may be used to program the sensor:

 Detect minimum and maximum limits, or
 Use Auto-Window feature to centre a sensing window

The sensor may be programmed either via ANALOG push-button, or
via a remote command (remote teach).
Remote programming may be used to disable the push-button,
preventing unauthorized personnel from adjusting the programming
settings. To access this feature, connect the Remote Teach wire of
the sensor to 0 Vdc, with a remote configuration switch between the
sensor and the voltage.

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”:

around the taught position.

0.04 seconds < T < 0.8 seconds

Indication of sensor status and relative signals

Positive or negative output slope programming

The sensor may be programmed for either a positive or a negative output slope, based on which limit is
taught first (see pictures).

 If the Minimum limit is taught first, the slope will be positive.
 If the Maximum limit is taught first, the slope will be negative.

The analogue output signal, is automatically distributed over the width of programmed sensing window.
In the event of signal loss for more than 2 sec., the analogue output goes to 3.6mA or 0Vdc, which may
be used to trigger an alarm.

General Notes on Programming

The sensor will return to RUN mode if the first TEACH condition is not registered within 120 seconds.
After the first limit is taught, the sensor will remain in PROGRAM mode until the TEACH sequence is
finished.
To exit PROGRAM mode without saving any changes, press and hold the programming push button >
2 seconds (before teaching the second limit). The sensor will revert to the last saved program.

Two TEACH methods may be used to program the sensor:

 Detect minimum and maximum limits, or
 Use Auto-Window feature to centre a sensing window around the taught position.

This mode is particularly suitable if the sensor is used as background suppression (refer to drawing).

The sensor may be programmed either via DISCRETE push-button, or via a remote command (remote

Remote programming may be used to disable the push-button, preventing unauthorized personnel from
adjusting the programming settings. To access this feature, connect the Remote Teach wire of the
sensor to 0 VDC, with a remote configuration switch between the sensor and the voltage.
Programming is accomplished by following the sequence of input pulses.

General Notes on Programming

The sensor will return to RUN mode if the first TEACH condition is
not registered within 120 s econds.
After the first limit is taught, the sensor will remain in PROGRAM
mode until the TEACH sequence is finished.
To exit PROGRAM mode without saving any changes, press and
hold the programming push button > 2 seconds (before teaching
the second limit). The sensor will revert to the last saved program.

N.O. (normally open) or N.C. (normally closed) mode selection

The sensor can be configured as NPN or PNP, by choosing between the N.O. and N.C. modes or
remote line. A pulse series along this line switches the sensor between N.O. / N.C and PNP / NPN.

 N.O. configuration: sensor output is activated in presence of the target to detect.
 N.C. configuration: sensor output is activated when there is no target to detect.
