1. IntroductIon
1.1. Product Description
The Model 311 is an oil field service pressure transmitter with a ”NPT(F) pressure port fitting
(standard - optional ports available), 4-20 mA output and measures pressures up to 75,000
psi (5168 bar).
1.2. Warning
Pressurized vessels and associated equipment are potentially dangerous. The product de-
scribed in this guide should be operated only by personnel trained in the procedures that will
assure safety to themselves, to others, to the equipment, and to the product. Specific warnings
are noted as in specific installation/operation sections.
1.3. Unpacking/Inspection
The Model 311 was carefully tested, inspected and packed. Upon receipt of the shipment thor-
oughly inspect the transducer. If you see any visible signs of obvious shipping damage, notify
the freight company immediately.
1.4. Using This Manual
This manual is intended to help the end user install, maintain, and provide general service of
the Blue Ribbon Corp. Model 311 pressure transmitter. The user should have a general under-
standing of current loops and general instrument control. The Model 311 is a precision instrument
and should be given the same care as any other precision instrument during installation and
operation.

2. InstallatIon
2.1. Mounting/Process Connection
The standard Model 311 transducer is supplied with a ¼” NPT(F) pressure port. Installation
of the device shall be in accordance with industry standard pipe fitting requirements for this
size. Torque shall only be applied to the transducer during installation (or removal) from the
wrench flats provided on the pressure port. As a general rule of thumb, the device shall be
torqued “wrench-tight” to preclude leakage from the process connection. Contact Blue Ribbon
Corp. sales personnel for additional information if required, or for specific installation require-
ments for non-standard process connections.
Insure media is compatible with 15-5 SST (standard material, optional materials available,
check part number (Appendix A) to verify wetted material) to avoid premature corrosion of the
diaphragm. This can cause performance degradation and eventual sensor rupture/failure.
Properly tighten process connections before applying pressure to insure no leaks or mechani-
cal failure can occur.
Never insert sharp objects into diaphragm. This could cause permanent damage to the sensor
and/or mechanical failure/diaphragm rupture.
2.2. Power Supply Connection
For best operation, the pressure transmitter needs clean, regulated power with an output im-
pedanance less than 20 Ω. Minimum voltage is 10 volts with no resistive loading, to a maxi-
mum of 36 Vdc (Z, P + X Series) (28 Vdc for I, AI + GI Series units). As loads are added to the
current loop (galvanic barriers, current measuring devices resistors), the minimum excitation
voltage must increase in order to maintain proper operating voltage.
Exceeding maximum supply voltage can damage electronics and cause malfunction or failure,
and can cause an explosion with Intrinsically Safe units. Please refer to the attached IS con-
nection diagram (Appendix B), and applicable local codes, for proper electrical installation.
Always inspect/clean electrical connection and sealing surface prior to installation.

Install only after verifying both input power and line pressure are off and at zero.
Avoid contact with exposed leads or connector pins, high voltage may be present on leads
and can cause electrical shock.
Observe safe ESD handling precautions to avoid static damage to sensitive components.

2.4. Environment
The typical operating temperature range for the electronics is from -40°F (-23°C) to 185°F
(85°C). The unit should be mounted as close to the process as possible with the ambient tem-
perature surrounding the electronics in the range as specified above.
Exceeding maximum temperature rating can cause electronics malfunction or failure, and is
an explosion risk with IS units.
Protect electrical connection from direct/continued exposure to fluids. Moisture ingress can
occur and cause eventual electrical failure.
3. operatIon/MaIntenance/HandlIng
The Model 311 is designed to give a 4-20 mA output directly proportional to pressure. Specif-
ic pressure range, input voltage requirements and electrical connections are marked on unit.
See Appendix A for all performance specifications. Standard electrical connection is a HEYCO
connector on the I.S. approved product +½” NPT M on Explosion Proof Series and pressure
port is ¼” NPT(F). Appropriate mating con nections are required for proper installation and
safety. Other port and electrical connections are available and noted as option code in part
number. See Appendix A for list of options.
Replace broken fasteners (available through the factory) as they may compromise the seal and
cause contamination and/or electronics failure.
Unit can be hot when removed from service. Wear protective gloves when handling unit in this
condition.
