ECHOTEL® 961
Ultrasonic level switches
FOR HYGIENIC USE
DESCRIPTION
Echotel® 961 ultrasonic level switches require no calibration
to detect the presence of any liquid in less than 1s. Foam is
ignored by technology, so that the unit only detects the presence or absence of liquid. The pulsed wave technology permits the unit to resist turbulence, aeration, suspended solids
and build up.
Echotel® 961 has both 3A and EHEDG approval for use in
hygienic applications.
Echotel® 961 offers either current shift or relay output.
For LIQUID LEVEL switching applications
F E AT U R E S
• No calibration
• 2-wire loop powered with mA output, AC/DC line powered
with integrated relays.
• Continuous selftest with selectable error output
• LED identification for:
- process alarm
- error of transducer, electronics or electrical noise
interference
- wet/dry status of transducer
• Push buttons for manual testing of alarm and error signals
• Adjustable time delay up to 45 s
• Suitable sensor design for CIP/SIP cleaning
• Model 961 suited for SIL 1 and SIL 2 loops (full FMEDA

TECHNOLOGY
The Echotel® 961 operates on a two crystal pulsed or
“transmit-receive” principle which applies a high frequency
electronic burst to the transmit crystal. The signal is then
converted into ultrasonic energy and transmitted across the
sensing gap towards the receiver crystal. When there is air
in the gap, the high frequency ultrasonic energy will be
attenuated, thereby not allowing the energy to be received.
When there is liquid in the gap, the ultrasonic energy will
propagate across the gap and the output will indicate a
reception of the signal.

FUNCTIONS
Adjustable time delay:
The Echotel® 961 provides a fast response time of typically 0,5 s. In applications with turbulent or boiling surfaces,
this may lead to scattering of the output. For these applications, the user can adjust via a potentiometer a time delay
from 0,5 to 45 s and avoid false switching.
Pushbuttons for manual check: The alarm output and
the error signal of the Echotel® 961 can be manually
checked via pushbuttons. For loop powered units, the loop
test pushbutton will sequentially check the shift of loop current. For relay operated units, the level test pushbutton will
make the relay change from energized to de-energized status or vice versa. Pressing the fault/malfunction pushbutton
stops all transmit pulses, which simulates an electronics
failure, and tests the selected output signal.
LED identification:
The «Wet» LED reports liquid in the gap. An additional
«Level» LED on the 961 with relay output reports alarm.
With the current shift version, the corresponding 8 or 16 mA
LED will report alarm or safe condition.
«Fault» LED reports a malfunction of the unit. The blinking sequence of the LED identifies the failure (electronics,
transducer or electrical noise interference).
«Malfunction» LED (only for units with relay) confirms
that the malfunction relay is energized in normal operation
Selectable error signal:
The error signal of loop powered units can be set for either
3,6 or 22 mA. The separate malfunction relay of the 961
can be set for independent or joint operation with the alarm
relay.
