14.1.1 Pressure limits

Gauge pressure limits
The transmitter models 266CRX/JRX can operate without
damage within the following overpressure limits:
Sensors Filling fluid
C to R Silicone oil
C to R Fluorocarbon
(Galden)
Static pressure limits
The transmitter models 266CRX/JRX can operate within the
specifications with the following overpressure limits:
Sensors Filling fluid
C to R Silicone oil
C to R Carbon fluoride
(Galden)
The overpressure limits and upper static pressure limits can be
lowered by means of the nominal pressure rating of the
diaphragm seal flange; see remote seal data sheet
DS/S26.seal
Test pressure
The transmitters can withstand a pressure test with the
following line pressure without leaking:
