Pressure transmitter EJA110E type

Description

1. Product Overview

The Pressure Transmitter EJA110E is a high-performance, industrial-grade differential and absolute pressure sensing instrument engineered for continuous process monitoring and control. It converts pressure signals into standardized 4–20 mA/HART outputs for integration into DCS/PLC systems, enabling precise measurement in petrochemical, power generation, and water/wastewater operations. The EJA110E’s key value lies in its industry-proven accuracy, long-term stability, and rugged construction designed for corrosive and high-vibration environments. As a strategic asset, it reduces process variability, supports regulatory compliance, and lowers total cost of ownership through extended calibration intervals and reduced downtime.

2. Key Specifications & Technical Characteristics

• Sensor type: Silicon piezoresistive sensing element with advanced temperature compensation.

• Pressure ranges: Gauge, absolute, and differential ranges configurable; typical spans from ±2.5 kPa to 100 MPa (model-dependent).

• Accuracy: Typical total performance up to ±0.075% of span (refer to model datasheet for exact span-dependent figures).

• Output signal: 4–20 mA with HART protocol (2-wire); FOUNDATION Fieldbus and digital options may be available.

• Materials and wetted parts: Stainless steel (SS316/SS316L) housings and diaphragm options; Hastelloy or Monel available for corrosive media upon request.

• Sealing and electronics housing: IP66/IP67/NEMA 4X-rated enclosures with explosion-proof configurations (Ex d/Ex ia) for hazardous locations.

• Temperature range: Operating ambient and process temperature ranges suitable for -40°C to +85°C service (application dependent).

• Power requirements: Typical 10–42 VDC loop power for 4–20 mA operation.

• Mounting and connections: Flanged, threaded, or sanitary process connections; variety of electrical entry options (M20, 1/2″ NPT).

• Stability and drift: Low zero/span drift with long-term stability design for multi-year mean time between calibrations.

• Physical characteristics: Compact transmitter head or remote-sealed assemblies, rugged stainless-steel construction; typical weight varies by configuration.

• Packaging options: Bulk-packaged for project deliveries, individually boxed with foam protection for retail/technical orders, and palletized for container shipping.

• Documentation and certification: Supplied with calibration certificate, material certificates (upon request), ATEX/IECEx/CSA/UL and SIL/functional safety documentation where applicable.

• Shelf life and storage: Electronic device—store in dry environment 0–50°C, recommended use within 24 months for warranty alignment.

3. Core Industrial Applications

• Primary industries: Oil & gas upstream and midstream, petrochemical and refining, power generation (including nuclear and thermal), water & wastewater treatment, HVAC and building management, pharmaceuticals, pulp & paper, and mining.

• Specific operational use cases: Pressure monitoring in separators, custody transfer lines, boiler drum level via differential pressure, pump monitoring, filter differential pressure, steam and condensate systems, and level measurement in tanks using differential transmitters.

• Why it outperforms alternatives: The EJA110E combines proven silicon sensing technology with advanced temperature compensation and robust materials selection, delivering superior accuracy across wide ranges, reduced thermal error, and long-term stability that minimizes recalibration and maintenance costs. Its explosion-proof and remote-seal options extend applicability to the harshest sites, reducing replacement frequency and unplanned downtime.

• Efficiency, durability, cost advantages: Higher measurement precision enables tighter control loops and process optimization (yield and energy savings). Durable wetted materials and rugged housings extend service life in corrosive and high-vibration settings, lowering lifecycle cost versus lower-grade transmitters.

4. Competitive Advantages

• Quality consistency: Manufactured under strict quality systems with factory calibration and traceable certificates to ensure repeatable performance across batches.

• Supply reliability: Production planning and project-tailored lead times supported by inventory buffers for standard configurations and long-term supplier agreements for critical components.

• Logistics capability: Available for bulk 20 MT project shipments, containerized exports with export packaging, and expedited air shipments for critical spares; experience handling customs documentation and hazardous goods logistics.

• Price competitiveness: Competitive unit pricing for project buys, volume discounts, and package offers (transmitters with manifolds and impulse lines) to lower installed cost.

• Sustainability and environmental benefits: Long service life and low maintenance reduce waste and replacement frequency; available RoHS-compliant materials and options for reduced packaging on bulk orders.

• Technical support and documentation: Comprehensive user manuals, installation and calibration guides, field diagnostics via HART, and access to field application engineers for commissioning and troubleshooting. SIL and hazardous-area certificates and application notes available to support safety-case and compliance needs.

5. Commercial & Supply Information

• Minimum order quantity (MOQ): BULK 20MT.

• Loading capacity (MT per container): Depends on configuration and packaging density; typical full container load (FCL) planning for instrument crates—consult logistics team for precise MT per 20′ or 40′ container based on selected packing and accessory quantities.
