SIL Safety Manual for
Echotel Model 961/962
Model 962
Ultrasonic
Level Switches
This manual complements and is intended to be used with
the Magnetrol Echotel Model 961/962 Ultrasonic Single and
Dual Point Level Switches Installation and Operating Manual
(Bulletin 51-646, dated October 2008 or later).
Application
Echotel Model 961/962 ultrasonic level switches utilize
pulsed signal technology to detect high, low, or dual-
point level in a broad range of liquid media applications.
The advanced self-test technology provides reliability
and continuous testing of electronics, transducer, piezo-
electric crystals, and electromagnetic noise.
Benefits
The Echotel Model 961/962 ultrasonic level switches
provide the following benefits:
⢠Single or dual point liquid level measurement
⢠Adjustable time-delay for turbulent aerated liquids
⢠Reliable liquid level measurement independent of
changes in media density, conductivity, or temperature
⢠Relay output or mA current shift with separate
malfunction indication
⢠Integral or remote mount electronics
⢠Pulsed signal technology
⢠Extensive FM, CSA, and ATEX explosion proof and
intrinsically safe approvals
⢠Suitable for Safety Integrity Level (SIL) 2 loops
