Programmable Level Pressure Transmitter digitally compensated Series 36 X S (stretto line) / rangeable / digital and analog output This pressure transmitter is designed for level measurement in narrow downhole applications where highest accuracy is required. - Only 16 mm diameter Product Benefits: - Mathematically compensated - Programmable, assisting inventory reduction - Filtering function 2 ms...30 sec - Improved surge protection - Bus-system capabilty (up to 128 transmitters) 36 X S level transmitter is available in two different versions: • PAA-36 X S Absolute Pressure, 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 Relative Pressure, Zero at ambient 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. Programming With the KELLER software READ30 and PROG 30, a RS485 converter (i.e. K-102, K-104 or K-107 from KELLER) and a PC (Laptop), the pressure can be displayed, the units changed, and new gain or zero set. The analog output can be set to any range within the compensated range. Electrical Connections Wire Color Diaphragm position mark

KELLER Specifications Standard Pressure Range FS and Overpressure in Bar PR-36 X S PAA-36 X S Note: The ranges 100, 200 or 500 mbar are realized with the 1 bar range. Accuracy for these ranges is +2 mbar (0...50°C) PAA: Absolute. Zero at vacuum All intermediate ranges for the analog output are reali­za­ble with no surcharge by spreading the standard ranges. The Errorband rises proportionally. PR: Vented Gauge.
