Honeywell STG78S High Accuracy Gauge Pressure Transmitter with 0.05% Reference Accuracy HART 4-20mA Output

Honeywell STG78S Gauge Pressure Transmitter with Improved Accuracy

The Honeywell STG78S is a SmartLine gauge pressure transmitter engineered for loops where a tenth of a percent of span is the difference between good product and rejected product. This configuration is supplied with +/-0.05% reference accuracy, HART 7 digital communication and a 316L stainless steel barrier diaphragm, so the reading you commission is the reading you still trust twelve months later.

Part number: STG78S-E1G000-1-C-CHS-12C-B-00A6-FX,F1,F5,TP-0000. New and original in factory packaging, 12 months factory warranty.

Accuracy Improvement Details

• +/-0.05% of calibrated span reference accuracy instead of the 0.1% class usually fitted on general purpose gauge loops.
• Digital trim through HART removes the zero and span drift that analog-only transmitters pick up between calibration cycles.
• +/-0.02% URL per year long-term stability keeps drift well inside the accuracy band, extending calibration intervals.
• Temperature compensation across -40 to +85 C ambient suppresses the warm-up and day-night error common on uncompensated sensors.
• 316L barrier diaphragm with 316 stainless steel process head resists corrosion pits that would otherwise shift the zero point.

Technical Specifications

Typical Applications

• Boiler feedwater and pump discharge pressure where tight control tolerances are required
