TRANSDUCER INSTALLATION
GENERAL
Transducers have become more popular in recent years as a way to precisely control or maintain liquid
levels in tanks, canals, sewer systems and other critical sites. They are available in a wide range of
options from types of scale, materials of construction, cable lengths and signal types. Controls, Inc.
has developed general guidelines when using a transducer in your application.
•
Signal Type – We recommend specifying a 4-20mA output in your transducer. The current
signal is less susceptible to noise and can be used over longer distances than the voltage
output types.
•
Appropriate Range – Use a transducer that matches your needs. For example, if you need to
start and stop the pump between 10 and 40 inches, use a 0 to 10’ transducer. The closer the
working range is to the actual range, the better performance and control you will achieve.
•
Material – Know the type of liquid you will be subjecting your transducer to. Typical materials
range from stainless steel to titanium. The costs can be considerably different, so talk to a
specialist.
Controls, Inc. does stock transducers and can assist in selection. Contact a sales engineer for more
help.
When using a transducer for start, stop and possible speed control, you first need to tell the control
panel what type of transducer you are connecting. This is done in the
Transducer Configuration
menu. See Controller Setup Menu for more details.
