Series 36XW submersible pressure transmitters are highly precise level transmitter with integrated temperature sensors for active temperature and non-linearity compensation. Available with sensors suitable for water depth monitoring of 1 up to 300m H20. RS485 Modbus RTU output as well as standard rangeable voltage and current outputs. PR36 units are available with a vented tube and PAA36 units would require a separate barometric sensor for accurate water level calculations. Suitable for fresh or sea water applications.
Hazardous Area Approved
The Series 36XW uses a stable, piezoresistive transducer and integrated tempertaure sensor to allow for temperature dependencies and non-linearities of the transducer to be mathematically compensated. The micro-processor electronics with integrated 16-bit D/A converter allows for analogue signal outputs as well as the digital output to be transmitter. Up to 128 individual addresses are available allowing 128 transmitters to be interconnected on a single network using Modbus RTU or Keller BUS protocol.
PAA-36 X W Absolute, Zero at Vacuum
This probe is applied when the atmospheric pressure is measured by a separate barometer and when the water level is calculated as the difference between the absolute value and the ambient pressure. Cable material Polyolfin (PE-based).
PR-36 X W Gauge, Zero at atmospheric Pressure
This probe is fitted with durable cable with an integral vent tube to the atmosphere. These level transmitters can be subject to internal condensation caused by installations in cold water on warm, humid days. If the reference tube is not terminated in a warm, dry enclosure, KELLER recommends the use of a purpose built cartridge filled with a silica gel which is fitted at the end of the reference tube. Cable material Polethylene (PE)

Serial Interface
The X-line products have a digital interface (RS485 half duplex), which supports the MODBUS RTU and KELLER Bus protocols.
Software
The licence-free CCS30 software can be used for initial configuration, or to record the measured values. An RS485 converter (i.e. K-114 or USB-i485) and a PC, or Laptop, allows the pressure to be displayed, units changed, a new gain or zero set and other calibration adjustments. The analogue output may also be adjusted to any range within the compensated range. Click the CD below to go to the download page.
