ST3000 series 900 remote seal pressure transmitters are available in a variety of configurations to meet the needs of a wide range of pressure measurement applications.
The guide details the ST 3000 Series 900 remote seal pressure transmitters, which are designed for level measurement in pressurized vessels and flow measurement of slurries in chemical processing. It describes the piezoresistive sensor technology, dual‑way communication, and integration with Honeywell’s Process Knowledge System.
Key features include analog 4‑20 mA output, DE digital, HART and FOUNDATION™ Fieldbus options, high stability (+/‑0.01%/yr), 470‑year MTBF reliability, and robust housing meeting NEMA 4X and explosion‑proof standards. The document also provides operating conditions, supply voltage, accuracy, turndown ratios, and detailed model‑selection tables for various seal types.
| Output options | Analog 4‑20 mA, DE digital, HART, FOUNDATION™ Fieldbus |
|---|---|
| Supply voltage | 10.8 to 42.4 Vdc at terminals |
| Stability | +/-0.01% per year |
| Reliability | 470 years MTBF |
| Accuracy (Analog Mode, STR93D) | +/-0.20% of calibrated span or URV |
| Turndown ratio (STR93D) | 110 to 1 |
| Maximum pressure (flange rating) | 750 psi (52 bar) |
They can provide a 4‑20 mA analog output, Honeywell Digitally Enhanced (DE) digital output, HART, or FOUNDATION™ Fieldbus output.
The transmitters have a stability of +/-0.01% per year and a reliability of 470 years MTBF.
The required supply voltage is between 10.8 Vdc and 42.4 Vdc at the terminals.
