for dc circuits: connect protection diodes in the correct polarity across the relay coil    

•

for ac circuits: connect a Voltage Dependent Resistor (VDR) or other ac compatible 
component (such as zeners and protection diodes in combination) in the correct 
polarity across the relay coil

• The transmitter is specified for use at temperatures ranging from –40 

°

C to 

85

°

C (–40 

o

F to 185 

o

F): if your process temperature is outside this range, a 

standard option is available with a thermal isolator.

• Before mounting the SITRANS LC 500, check to ensure the threads are 

matching to avoid damaging them.

take care that the tensile load does not 
exceed probe or vessel rating

the tank wall, take care that the product 
does not push the cable against the tank
