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.

Overview

Ultrasonic sensors excel in position-monitoring applications and in applications involving clear or multi-colored targets.
QT50UVR sensors are available in a variety of models: dc sensors with either analog or two discrete outputs, or universal

voltage models that feature an SPDT electromechanical relay for switching larger loads. Programming and setup for the
universal voltage models are accomplished using the sensor’s two push buttons.

Models are available with Teflon sensor face and hex nut, plus Teflon-coated transducer and special o-rings for use in
harsh environments, such as fill-level monitoring in an acidfilled tank.

1

To order the 9 m cable models, add suffix W/30 to the model number of a cabled sensor (for example, QT50UVR3W w/30).
Models with a QD connector require a mating cable.

U-GAGE QT50UVR Series Sensors

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:

In metric
units:

C

= speed of sound in meters per second C

m/s

TC = temperature in °C TF = temperature in °F

In English units:

= speed of sound in feet per second

ft/s

Temperature Compensation

The speed of sound changes roughly 1% per 6° C (10° F). QT50U series ultrasonic sensors have temperature
compensation available; temperature compensation will reduce the error due to temperature by about 90%.

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 farther away from the sensor. Conversely, a decrease in
air temperature shifts both limits closer to the sensor. This shift is approximately 3.5% of the limit distance for a 20° C
change in temperature. With temperature compensation enabled, the sensor will maintain the window limits to within

1.8% over the entire -20° to +70° C (−4° to +158° F) range.

NOTE:

• If temperature compensation is enabled, 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.

• With temperature compensation enabled, the temperature warmup drift upon power-up is less
than 1.0% of the sensing distance. After 30 minutes, the apparent switchpoint will be within

0.5% of the actual position. After 60 minutes, the apparent switchpoint will be within 0.3% of
the actual position.

Configuration

The sensor can be configured for one of three output response times and to enable or disable temperature compensation.
Both are accomplished using the sensor’s Speed push button, using the procedures described below. A button click is
defined as: 0.04 ≤ Click ≤ 0.8 sec.

1. Select the output response time.

Action

Click the Speed button until the desired output response time is
selected.

• Teach individual minimum and maximum limits.

• Use the Auto-Window feature to center a sensing window around the taught position.

Teaching Minimum and Maximum Limits

Teach procedures are identical for window-limit and fill­level control models. Window-limit models function as
shown in the figure on the right, and fill-level control
models function as shown in Figure 5 on page 5. To
readjust minimum or maximum limits, repeat the teach
procedure.

Action Result

Position the target for the second limit.
Click the TEACH button. The sensor stores both limits and Output LED turns solid amber.

The sensor returns to Run mode.

The Fill-Level Control mode provides the switching logic required for fill-level, web tensioning control, and similar
applications. In this mode, the output energizes when the target reaches the first sensing window limit, and stays
energized until the target moves to the second limit. The output then de-energizes at the second limit and does not re­energize until the target moves, again, to the first limit.

Installing the Chemical-Resistant Models

The sensor may be threaded directly into the side of a tank (see dimensions for hole diameter and thread specifications),
or into a non-threaded hole, using the included threaded nut. Recommended through-hole size: 56.5 ± 0.5 mm.

For a non-threaded hole, install an o-ring onto the flange, and insert the flange completely into the hole until the sensor
front surface is against the tank’s exterior surface. Place the other o-ring into the groove on the Teflon nut, and thread the
nut onto the flange. Tighten enough to eliminate gaps between the flange and the tank surface. This will ensure that the o­rings are fully compressed.
