Reference Manual 00809-0100-4514, Rev BA January 2008 Rosemount 1154 Transmitters with Flange Options A, D, H, J, L, or M are shipped with Swagelok fittings for process connections. Included are front ferrule, rear ferrule, and nut. Ensure that the fittings are placed on the tubing with the orientation and relative position shown in Detail A, Figure 2-5 on page 2-7. Process tubing used is 3/8-inch outside diameter, and of suitable thickness for the pressure involved.
Reference Manual 00809-0100-4514, Rev BA January 2008 Rosemount 1154 The piping between the process and the transmitter must transfer the pressure measured at the process taps to the transmitter.
Reference Manual 00809-0100-4514, Rev BA January 2008 Rosemount 1154 Signal wiring need not be shielded, but twisted pairs yield the best results. In electrically noisy environments, shielded cable should be used for best results. Do not run signal wiring in conduit or open trays with power wiring, or near heavy electrical equipment. Signal wiring may be ungrounded (floating) or grounded at any place in the signal loop. The transmitter case may be grounded or ungrounded.
Reference Manual 00809-0100-4514, Rev BA January 2008 Rosemount 1154 INSTALLATION PROCEDURES Installation consists of mounting the transmitter and conduit and making electrical connections. Procedures follow for each operation. Mechanical Transmitter Be careful not to break the neck seal between the sensor module and the electronics housing. The threaded interface between the sensor module and the electronics housing is hermetically sealed before shipment.

Calculate correction factor: 0.75 % ------------------------ × 1, 200 psi = 0.9% differential input 1,000 psi 3. Calculate zero adjustment correction in terms of pressure: 0.9 % × – 100 inH 2 O = – 0.9 inH 2 O 4. Convert pressure correction to percent of input span: – 0.
Reference Manual 00809-0100-4514, Rev BA January 2008 Rosemount 1154 Equalize pressure to both process connections, and turn the zero adjustment until the ideal output at zero differential input is observed. Do not readjust the span potentiometer. If the transmitter does not include zero differential pressure within its calibrated span, the zero effect or zero correction can be determined before the unit is suppressed or elevated to eliminate the zero effect after correcting for the span effect.
