Page 3: Principle Of Operation Introduction Echotel Model Level Switches utilize ultrasonic contact technology for measuring level in clean liquid applications. Principle of Operation The Model Level Switch uses ultrasonic energy to detect the presence or absence of liquid in a transducer gap.
The basic principle behind ultrasonic contact tech- Ultrasonic nology is that high-frequency sound waves are easily transducer These instruments use electronic components that may be damaged by static elec- tricity present in most work environments. The following steps are recommended to reduce the risk of component failure due to electrostatic discharge. Page 6 Wiring 2. Use of 14—22 AWG twisted shielded pair wire is recommended.
NOTE: Observe all applicable electrical codes and proper wiring procedures. Make sure the power is turned off. Page 7 2. The table below lists the relay contact positions for all possible combinations of power failure, condition of the transducer gap, and fail-safe jumper position. The user must decide which combinations constitute fail-safe and alarm conditions, and then select the appropriate relay wiring and fail-safe position. Page 8: Reference Information Reference Information Troubleshooting Caution: In hazardous areas, do not remove housing cover until power is disconnected and atmosphere is deter- mined to be safe.
Verify power and control circuit wiring. Make sure liquid is filling the transducer gap. Page 9: Specifications Specifications 3. Page Replacement Parts 3.

Optional: Order code for thread-on mounting flanges, consult factory for other sizes or materials. The signal is converted into ultrasonic energy and transmitted across the sensing gap toward the receiver crystal. When there is air in the gap, the high frequency ultrasonic energy will not be received. When there is liquid in the gap, the ultrasonic energy will propagate across the gap and actuate the relay.
