ECHOTEL® 91S/92S - Magnetrol International

ECHOTEL® 91S/92S
Ultrasonic Level Controls
With Continuous Self-Test
The 91S/92S ultrasonically detects liquid level over a broad
spectrum of liquids.
The single point unit (91S) has one control relay and one
dedicated malfunction or self-test relay contact closure.
The dual point relay design (92S) has two control relays
and one dedicated malfunction relay.
Both versions also incorporate a unique, continuous selftesting feature which automatically verifies the integrity of
the unit, including the crystal bond.
Series 91S/92S with integrated alarm
relay(s) and selftest relay
F E AT U R E S
* No calibration required.
* Single tip design or dual point transducer in a sturdy
machined body design.
* Unique continuous self-test checks crystal bond, sensor,
and circuit integrity with or without liquid in the gap.
* Relay contacts with separate malfunction indication.
* Transducer lengths from 30 - 3300 mm.
* Field selectable fail-safe.
* Integral or remote mount electronics.

The Series 91S/92S 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 sound energy and transmitted
across the sensing gap toward the receiver crystal. When
there is air in the gap, the high frequency sound energy will
be attenuated, thereby not allowing the energy to be
received. When there is liquid in the gap, the sound energy
will propagate across the gap and the relay output will indicate such a reception of the signal.
Self-testing is accomplished without additional crystals and
a minimum of additional circuitry. The electronics detection
circuit looks for low amplitude signals that pass between
the crystals through the frame of the sensor. This allows the
entire sensor, including the bond between the crystals and
the sensor face, to be tested along with the electronics.
