Model-specific technical reference
FD3051T range is a family envelope
The manufacturer's FD3051T product page describes the selectable family from 5 kPa to 260 MPa and lists 0.25%, 0.5% and 1.0% full-scale accuracy options. These endpoints are not one calibrated span. For each instrument tag, request the full model code, pressure type, calibrated lower and upper range, process connection, wetted materials, output and applicable certificate. The published manufacturer data is not an offer of a specific configuration or evidence of our dealership, stock or supply rights.

Product overview
Measured pressure and range selection
Pressure transmitters convert gauge, absolute or negative pressure into a control-system signal. A published FD3051T reference family spans low-pressure applications beginning at 5 kPa and high-pressure configurations reaching 260 MPa; those endpoints describe a family range, not one sensor capsule. The RFQ should identify normal pressure, minimum and maximum operating pressure, allowable overpressure and whether vacuum measurement is required.
Accuracy, temperature and signal
Published accuracy options for the referenced family are 0.25%, 0.5% and 1% of full scale, with a stated operating-temperature range of -20 to 80 degrees C. Output choices include 4-20 mA, 1-5 VDC and RS485, while HART and Modbus RTU are listed communication options. The buyer must state the control-system input, loop power, cable entry and whether local indication is needed.
Process connection and environment
A pressure range alone does not define an interchangeable instrument. Include the thread or flange connection, diaphragm and wetted materials, fill fluid, enclosure material, ingress rating, ambient conditions and hazardous-area classification. For sour or corrosive service, attach the process composition and the project material specification instead of selecting by pressure only.
RFQ checklist
Send the instrument datasheet, tag list, calibrated span, alarm or trip duty, quantity and destination with the inquiry. Ask the proposed source to return a signed model code, accuracy statement, dimensional drawing and calibration documentation. IP65 and explosion-protection markings shown on a product page remain configuration claims until the exact ordered model and certificate scope are verified.

Frequently Asked Questions
Does one pressure transmitter cover 5 kPa to 260 MPa?
No. The figures describe the endpoints of a product family. The calibrated capsule, overpressure limit and process connection must be selected for each tag.
Which signal details belong in the RFQ?
State 4-20 mA, voltage or RS485 requirements, HART or Modbus protocol, loop power, display, cable entry and control-system compatibility.
Can an explosion-proof configuration be assumed?
No. Request the exact protection concept, certificate, model coverage, gas group, temperature class and destination acceptance before approval.
Submit RFQ for Oil and Gas Pressure Transmitters
Send product, quantity, specification and destination details so the requirements can be reviewed with potential suppliers.
