1. General
1.1 Scope
A. This section describes the requirements for differential pressure and
gauge pressure transducers.
B. Under this item, the contractor shall furnish and install the transducer
equipment and accessories as indicated on the plans and as herein
specified.
1.2 Submittals
A. The following information shall be included in the submittal for this
section:
1. Data sheets and catalog literature for the transmitters.
2. Connection diagrams for equipment wiring.
3. List of spare parts and optional equipment.
2. Products
2.1 Differential Pressure and Gauge Pressure Transmitters
A. The transducers shall consist of an integral sensor and electronics
design.
B. Sensor:
1. The transmitter shall be based on a micro-machined silicon sensor
design. The sensor shall be compensated for the effects of varying
ambient temperature.
2. The transmitter pressure capsule shall have a standard
construction of 316 stainless steel wetted parts.
4. The transducer pressure sensor shall be protected from the effects
of pressure swings and spikes up to the maximum working
pressure (body rating) of the pressure capsule.
C. Electronics:
1. The standard transmitter enclosure shall be epoxy-polyester coated
with a NEMA 4X / IP65 rating.
2. The transmitter shall be a two-wire loop powered device that
signals on the 4-20 mA standards.
3. The transducer shall provide 0.25% of span accuracy.
Industry
4. The transmitter shall have the ability to electronically compensate
for the effects of mounting position on the sensor. Furthermore, the
transmitter shall be able to force the loop current to various values
to aid in loop setup and testing.
5. Temperature Limits: Ambient -22 to 185 Deg. F with integral meter.
Process: -40 to 185 Deg. F. Humidity limits: 0-100% RH.
The pressure transmitters shall be Siemens Sitrans Pressure Z transmitters. Manufacturer/Model No. Siemens 7MF1564 (Pressure Transmitter), Siemens 7MF1641 (Differential Pressure Transmitter) or approved equal.
2.2 Spare Parts
A. Spare parts for the equipment shall include the following, unless
otherwise noted:
1. One set of manufacturer’s recommended spare parts.
2. Extra operation manuals as required.
3. Operator Functions
3.1 Calibration
A. The transducers shall be fixed range and do not require calibration.
4. Execution
4.1 Installation
A. Follow manufacturer’s recommendation for the minimum upstream and
downstream installation requirements for the flow sensor.
B. Wiring between flow sensors and remote mounted signal converters
shall use cable type and procedures as per the manufacturers’
recommendations.
5. Warranty
The transmitter shall have a 1-year warranty.
