The Rosemount 3051 series pressure transmitter is one of the series products of Rosemount Corporation's pressure transmitters that have been tested in the power industry for 40 years. A design with high reliability, long-term stability, and easy maintenance. The optimal measurement concept can be achieved from design to installation, maintenance to operation.

pressure range

0.075% reference accuracy from 0-1.5 psi to 0-4000 psi (from 0-10 to 0-27580 kPa), including linearity, hysteresis, and repeatability

Range ratio reaches 100:1

Lightweight and compact size help achieve easy installation and handling

Under actual process conditions, it can achieve a stability of 5 years

Performance Specifications

Zero based range, reference conditions, silicone oil filling solution, and 316L stainless steel isolation diaphragm. ）

Reference accuracy

± 0.075% calibration range. The comprehensive effects include linearity, hysteresis, and repeatability.

For ranges with a range ratio less than 5:1, accuracy=± [0.025+(0.01) (URL/range)]% range

Environmental temperature impact

The overall impact is expressed as follows:

± (0.15% URL+0.15% range)/50 ° F (28 ° C)

The ambient temperature range is from -40 ° F to 185 ° F (-40 ° C to 85 ° C)

stability

For temperature changes of ± 50 ° F (28 ° C), reach ± 0.125% URL within 5 years.

vibration effect

Only considering the influence of resonance frequency, other vibration effects are ignored. Under resonance, a vibration of 15-2000 Hz is applied at any angle to the pipeline axis for testing, and the vibration effect is less than ± 0.1% URL/g

Power supply impact

Less than ± 0.01% calibrated range/volt

Installation location impact

Zero drift can reach 2.5 inH2O (63.5 mmH20), but it can be corrected. No range influence.

Radio frequency interference (RFI) impact

Less than ± 0.25% upper range limit (URL) (20-1000 MHz, 30 V/m, with piping for leads). Less than ± 0.25% range upper limit (URL) (20-1000 MHz, 10 V/m, using unshielded twisted pair, no piping).

Transient voltage protection limit

Compliant with IEEE C62.41, Class B

6 kV peak (0.5 μ s – 100 kHz)

3 kV peak (8 × 20 microseconds)

6 kV peak (1.2 × 50 microseconds)

Compliant with IEEE C37.90.1, shock resistance capability

SWC 2.5 kV peak, 1.25 MHz waveform
