Page 4: Introduction
1. Introduction The tuning fork level switch is a mechanical resonant device which excited by piezoelectric (PZT) elements. When the measured medium comes into contact with the tuning fork, it will change the feedback resonant frequency due to the damping resonances between the exciting PZT and receiving PZT. By detecting the frequency and appropriately tuning the sensitivity of tuning fork level switch on measured material, such device can easily operate for monitoring the alarm level of measured material. -

4. Terminals Arrangement Fig-1. SPDT contact output model Terminal Description: L+, N-: Power Supply NC, COM, No: Relay Output RT1, RT2: Remote-Test : Ground Connection COM, NO: PNP/NPN Output Description of terminal functions: L+, N-: Power Supply ... -
Page 7: Output Description
5. Output Description 1. Make sure provide power supply (L+/N-) in range of 20 to 250 (Vac or Vdc,50/60Hz) and output relay (Relay or PNP/NPN before wiring. Detail please see Fig-1. 2. RT1 and RT2 are the testing points that easy user to verify the situation. When the RT1 and RT2 are in electric short, it means the measured material is in contact with the tuning fork level switch. -

7. Output Mode FSH (FAIL-SAFE HIGH) PROTECTION: On the OUTPUT MODE, select Fail-Safe High Mode (FSH) and install the tuning fork switch at the high position. Relay Output: Normal Status: NO & COM contact of the relay are conducted and the Signal Lamp lights up when tuning fork level switch doesn't sense any materials. -
