Echotel® Models 960/961
Ultrasonic Level Switches
for Hygienic Applications
DESCRIPTION
Echotel® Model 960/961 Ultrasonic Level Switches use
pulsed signal technology for superior performance in
difficult process conditions, and to provide excellent
immunity from sources of electrical noise interference.
Extensive self-testing of the electronics and transducer
make this advanced switch suitable for a wide variety of
hygienic level switch applications.
Model 960 Switches use AS-Interface® (AS-i) bus digital
communications for high or low single point liquid level
measurement. The AS-i bus system provides a digital serial
interface with a single unshielded two-wire cable for
power and data transfer.
Model 961 is offered with either a 5-amp relay or a cur-
rent shift electronics. The relay output electronics has a
DPDT relay for level detection, and a SPDT malfunction
relay. The current shift version indicates 8 mA during nor-
mal operation, 16 mA as a level alarm condition and a
user-selectable 3.6 or 22 mA malfunction indication.
The 960/961 switches are designed for the stringent
requirements of hygienic applications. These switches are
offered with a deep-drawn 304 stainless steel housing that
is favorable to CIP and SIP procedures. A 20 Ra surface
finish is featured with hygienic Model 960/961 transducers.
These transducers are available with 11â2" & 2"
Tri-Clamp® fittings, and DN65 Varivent® Type N flanges.
FEATURES
⢠Self-test technology provides unsurpassed
reliability and testing of electronics, transducer,
piezoelectric crystals, and electromagnetic noise
