TRANSDUCER INSTALLATION
GENERAL
Transducers can be used on any of the three analog channels. The display supports pump inlet and
pump outlet pressure. 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 your pump
discharge can not exceed 80 PSI, use a 0-100 PSI transducer. Not a 0-500 PSI. 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.
