INSTALLATION AND OPERATING INSTRUCTIONS
RSU-C – Remote Sensing Tensiometer
You must use a 15/16" wrench (24mm) for the transducer.
The IRROMETER RSU-C is a pressure transducer sealed in a
stainless steel housing, which converts the 0 to 100 kPa tension
reading from the instrument into a 4-20mA current output. Any device
which can read a 4-20mA sensor and can supply between 9 and
36VDC can read the RSU-C.
For devices which cannot read a current loop but can read a voltage,
the RSU-V is available with a 0.5 to 4.5V output.
The calibration for the RSU-C is: (mA measured - 4)/0.16 = kPa
Note: Two wire insulated cable (suitable for direct burial) should be
used to connect RSU-C to Electronic Reading Device – #18 AWG
size (standard preferred)

- Page 2 — WARNING — Do Not use water containing chlorine or sulfur (distilled preferred) or cleaners containing chlorine or sulfur with the RSU-C. When de-airing the transducer equipped IRROMETER (Model RSU-C) 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.
