Model RSU-V
INSTALLATION AND OPERATING INSTRUCTIONS
®
RSU-V – Remote Sensing Tensiometer
The IRROMETER RSU-V incorporates a pressure transducer in a potted
waterproof housing. The RSU-V can be installed in the gauge port of any
IRROMETER, thus converting the reading to a voltage signal. Excitation voltage
required is 5 VDC.
Note 1: Consult the factory if modifying an existing MLT.
Note 2: Three wire insulated cable (suitable for direct burial) should be used to connect
Note 2:
RSU-V to Electronic Reading Device – #18 AWG size (standard preferred).

— WARNING —
Do Not use water containing chlorine or sulfur (distilled preferred)
or cleaners containing chlorine or sulfur with the RSU-V.
When de-airing the transducer equipped IRROMETER (Model RSU-V)
care must be taken to release the vacuum slowly. A sudden release
of the vacuum could cause damage to the pressure transducer,
rendering the instrument inoperable. Transducers damaged by
sudden release of the vacuum are unrepairable and would require
complete replacement of the entire transducer assembly.
