Honeywell STD730 High Accuracy Differential Pressure Transmitter with 0.05% Span Accuracy 4-20mA HART Signal

Honeywell STD730 Differential Pressure Transmitter

Differential pressure is usually a small number derived from two large ones, which is exactly why accuracy matters. The Honeywell STD730 delivers +/-0.05% span accuracy with 4-20 mA HART communication, so flow calculations, level inferences and filter blockage alarms stay inside the tolerance your control narrative assumes.

Model: STD730-E1AS4AS-1-C-CHS-12C-B-30A6-FX,F1,F5,TP-0000. New and original in factory packaging, 12 months factory warranty.

Accuracy Improvement Details

• +/-0.05% span accuracy supports orifice and averaging pitot flow loops without stacked error budgets.
• Coplanar body with 316L diaphragm keeps the measuring element rigid, reducing installation-induced zero shift.
• Static pressure and temperature compensation limits the error that appears when line pressure moves.
• HART digital trim corrects sensor offset at the loop and stores calibration in the electronics.
• +/-0.02% URL per year stability keeps accuracy class intact through long run lengths.
