Pressure transmitter S-20 type

Description

Product Overview
The Pressure Transmitter S-20 type is a rugged, industrial-grade piezo-resistive pressure sensor designed for continuous measurement of gauge and absolute pressures in demanding process environments. It delivers precise, real-time pressure data for control and safety systems across oil & gas, petrochemical, water treatment, and heavy industry. Its key value proposition is high-accuracy measurement combined with robust ingress protection and long-term stability, enabling tighter process control, reduced downtime, and lower total cost of ownership. Strategically, the S-20 addresses increasing market demand for reliable field instrumentation that supports digitalization and compliance with global safety and performance standards.

Key Specifications & Technical Characteristics

• Sensing principle: Piezo-resistive silicon diaphragm with welded stainless-steel wetted parts.

• Materials (wetted): 316L stainless steel (standard); optional Hastelloy C-276 or Monel for corrosive media.

• Housing material: Die-cast aluminum IP67 enclosure (optional stainless-steel housing for marine/harsh environments).

• Output signals: 4–20 mA (2-wire), HART-enabled; optional 0–10 V, Modbus RTU.

• Accuracy: ±0.1% FS (optional ±0.05% FS with factory calibration).

• Measurement ranges: from 0–1 bar to 0–600 bar (custom ranges available).

• Overpressure protection: Up to 2× rated span (model-dependent).

• Temperature range: Operating –40°C to +85°C; compensated –10°C to +70°C.

• Process connections: 1/4″ NPT, 1/2″ NPT, G½, flanged options to ANSI/DIN standards.

• Electrical connection: M20×1.5 cable gland or DIN connector.

• Long-term stability: <0.2% FS/year.

• Response time: <10 ms.

• Vibration and shock: Meets IEC 60068 and relevant industry vibration standards.

• Certifications: CE, ATEX/IECEx (intrinsically safe or flameproof variants), SIL2-capable designs available.

• Packaging options: Individual carton with shock protection; palletized wooden crates for bulk; export-grade fumigated pallets.

• Shelf life/maintenance: No chemical shelf-life; recommended calibration interval 12 months (site-dependent).

Core Industrial Applications

• Oil & Gas: Wellhead pressure monitoring, pipeline and custody transfer systems, compressor and pump protection. S-20 provides superior stability in high-pressure, high-temperature environments compared with ceramic or lower-grade sensors.

• Petrochemical & Refining: Reactor, distillation column and utility system monitoring where accuracy and chemical compatibility are essential.

• Water & Wastewater: Pump station control, filtration and reservoir level/pressure management, benefiting from low maintenance and IP-rated housings for wet environments.

• Power Generation: Boiler feed, steam systems and balance-of-plant pressure control, where fast response and SIL-capable options support safety systems.

• Industrial Manufacturing: Hydraulic systems, process automation, and factory instrumentation requiring long-term drift control and calibrated outputs for PLC/DCS integration.
  Why it outperforms alternatives:

• Higher accuracy and lower drift reduce rework and improve control loop performance.

• Robust wetted materials and optional exotic alloys increase service life in corrosive applications.

• HART and digital options simplify diagnostics and predictive maintenance in IIoT deployments.

Competitive Advantages

• Quality consistency: Factory calibration traceable to international standards and documented QA processes ensure repeatable performance across lots.

• Supply reliability: Committed manufacturing capacity and regional distribution planning reduce lead times; options for stocked configurations for rapid shipment.

• Logistics capability: Export-ready packaging, containerized bulk loading procedures, and experience with international customs and hazardous goods handling.

• Price competitiveness: Tiered pricing for volume purchases and value-engineered variants for cost-sensitive applications.

• Sustainability: Durable materials and long service life reduce replacement frequency; options for recyclable packaging on request.

• Technical support: Comprehensive datasheets, calibration certificates, dimensional drawings, installation guides, and access to field application engineers for project commissioning and troubleshooting.
