York Instrument MSP5100 High-Performance Stainless Steel Pressure Transmitter

Overview

The York Instrument MSP5100 High-Performance Stainless Steel Pressure Transmitter is engineered for mission-critical pressure monitoring in demanding industrial environments where long-term reliability, electromagnetic resilience, and media compatibility are non-negotiable. Based on piezoresistive sensing technology integrated into a monolithic stainless steel pressure cavity, the MSP5100 delivers stable, repeatable output across extreme thermal and mechanical stress conditions. Its all-metal, weld-free, O-ring-free construction eliminates elastomeric degradation pathways—making it suitable for high-cycle applications such as hydraulic actuation, compressor control, and process loops exposed to aggressive chemical media compatible with 316L stainless steel. Designed and manufactured in the United States, the transmitter complies fully with CE marking requirements for heavy-industrial equipment—including comprehensive immunity and emissions testing per IEC 61000-4 series and EN 55022. It operates from a tightly regulated 5 VDC supply and provides analog or digitally configurable output signals optimized for integration into PLCs, DCS systems, and embedded control platforms.

Key Features

• Monolithic pressure cavity machined from 17-4PH or 316 stainless steel—no brazing, no welds, no organic seals
• Proven endurance of >10 million pressure cycles under rated load, validated per industry-standard fatigue protocols
• Full electromagnetic compatibility (EMC) certification: 30 V/m radiated field immunity (IEC 61000-4-3), 1 kV surge protection (IEC 61000-4-5), and reverse polarity protection up to ±16 VDC
• Thermal compensation over -20°C to +85°C, enabling stable performance across wide ambient operating ranges (-40°C to +125°C)
• ±0.25% full-scale accuracy (combined nonlinearity, hysteresis, and repeatability) referenced to best-fit straight line
• Long-term stability of ±0.25% FS/year—critical for unattended operation in remote infrastructure and energy systems
• Burst pressure rating of 5× full-scale, with overpressure tolerance up to 2× rated pressure without permanent calibration shift
• Compact form factor (82.2 g) with IP67-rated housing for deployment in space-constrained or harsh-mounting scenarios

Sample Compatibility & Compliance

The MSP5100 is chemically compatible with any fluid or gas that does not aggressively attack 316L stainless steel—including refrigerants (R22, R410A, R134a), compressed air, hydraulic oils, water/glycol mixtures, steam (non-saturated), and many municipal wastewater streams. It is explicitly unsuitable for hydrochloric acid, hypochlorite solutions, or high-concentration chlorine environments. Regulatory compliance includes CE marking under the Low Voltage Directive (2014/35/EU) and EMC Directive (2014/30/EU), with test reports traceable to accredited laboratories. While not intrinsically safe or ATEX-certified out-of-the-box, explosion-proof enclosures or barrier systems may be deployed in conjunction with the transmitter for hazardous area use (Zone 2 / Class I Div 2). The device meets functional safety prerequisites for SIL-2 capable architectures when integrated into certified control systems per IEC 61508.

Software & Data Management

The MSP5100 operates as a stand-alone analog or digital sensor node without proprietary firmware dependencies. Output configurations—including voltage (0–5 V, 0–10 V), current (4–20 mA), or I²C/SPI digital formats—are set at time of order or via external calibration interface (where supported by variant). No embedded software requires validation; therefore, it imposes no burden under FDA 21 CFR Part 11 or EU Annex 11 for audit trail generation. When connected to SCADA or historian systems, raw sensor data inherits the validation status of the host platform. Calibration certificates—traceable to NIST standards—are provided with each unit, documenting as-shipped zero and span values, thermal error bands, and pressure cycle history. Optional factory recalibration services include ISO/IEC 17025-accredited reporting.

Applications

• Heavy-duty HVAC&R systems requiring robust response to refrigerant pulsation and thermal shock
• Hydraulic and pneumatic power units in mobile equipment (agricultural machinery, construction vehicles)
• Industrial process control loops in food & beverage, pharmaceutical water systems, and semiconductor tooling
• Energy infrastructure: boiler feedwater monitoring, pump station differential pressure, district heating return lines
• Water/wastewater treatment: filter backwash pressure, membrane integrity testing, lift station level inference
• Test benches for compressor development, valve characterization, and component endurance validation

FAQ

What is the recommended excitation voltage?
The MSP5100 is designed for stable operation at 5 VDC ±1%. Operation outside this range may affect accuracy and long-term drift.
Can the MSP5100 be used in saturated steam environments?
No. While the housing is 316 stainless steel, internal silicon sensing elements are not rated for direct exposure to saturated steam above 100°C. Use only with superheated steam or condensate-free vapor lines.
Is the device compliant with RoHS and REACH?
Yes. All materials and manufacturing processes conform to EU Directive 2011/65/EU (RoHS 2) and Regulation (EC) No. 1907/2006 (REACH), with full substance declarations available upon request.
Does the transmitter support HART or Foundation Fieldbus protocols?
No. The standard MSP5100 offers analog or basic digital outputs only. For smart protocol integration, consult York Instrument’s MSP5200 series or approved third-party signal conditioners.
How is long-term stability verified?
Each production lot undergoes accelerated life testing at elevated temperature and pressure load cycling. Individual units receive post-test calibration verification against baseline readings taken at t=0 and t=1000 hours.
