- Lightning Protection
- Bus-system capabilty (up to 128 transmitters)

36 X S level transmitter is available in two different versions:

• PAA-36 X S 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. Venting of the electrical cable to atmosphere does not have to be considered for these installations.

• PR-36 X S Gauge, Zero at atmospheric Pressure
This probe is fitted with a durable cable with an integral vent tube to the atmosphere. To prevent the formation of internal condensation caused by installations in cold water on warm, humid days, it is important to ensure only dry air enters the transmitter enclosure via the vent tube. If the vent tube is not terminated in a warm, dry enclosure, KELLER recommends and can supply a purpose built cartridge filled with a silica gel which is fitted at the end of the reference tube.
