Echotel® 961/962 - Sales Literature

ECHOTEL® 961/962
Ultrasonic level switches
DESCRIPTION
The Echotel® 961/962 series utilizes pulse signal technology to detect high or low level alarm(s) in a broad range of
viscous to light liquids. Pulsed signal technology provides
superior performance in applications suffering from foam,
aeration, heavy turbulence and suspendid solids.
The Echotel® 961 has a tip sensitive setpoint and is ideally
used as high or low level alarm.
The Echotel® 962 offers 2 setpoints on the same transducer, a tip sensitive setpoint and a second setpoint via a flowthrough upper gap. The unit is used for level alarm or to
control a pump in an auto fill/empty mode.
The Echotel® 961/962 is equipped with advanced diagnostics that continuously check the transducer and electronics.
The diagnostics also alarm for electrical noise interference
from external sources.

The Echotel® 961/962 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
Loop
Power
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 current shift or relay output will indicate a reception of the signal.

Adjustable time delay:
The Echotel® 961/962 provides a fast response time of typically < 1s. 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 1 to 45 s and avoid scatter of the output.
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
FUNCTIONS
Pushbuttons for manual check: The alarm output and
the error signal of the Echotel® 961/962 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:
Alarm LEDS report alarm status. For 962 models, the alarm
status per gap is reported. A separate LED on the 961
model (with relay output), reports independently from the
alarm status, whether the gap is immersed or not.
Pump Control (only 962 model with relays):
The model 962 with relays can be set for pump control or
level alarm. By selecting pump control (PC), the unit will
latch its 2 SPDT relays and provide automatic fill or drain
function between its 2 setpoints. In level alarm mode (LC),
the unit will detect either high and high-high or low and lowlow level alarm.
Selectable error signal:
The error signal of loop powered units (961/962) 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. The 962 with relays will always report a
malfunction via the alarm relay.
