(differential pressure gauge with capillary)
Capillary-type differential pressure gauge products are engineered for precision measurement in challenging environments. These instruments utilize capillary tubes filled with stable transmission fluids to isolate sensitive components from process media, ensuring longevity in high-temperature or corrosive applications. Modern designs achieve accuracy levels of ±0.5% full scale, with response times under 2 seconds across a working temperature range of -40°C to 450°C.
The latest capillary-type differential pressure gauges incorporate three critical innovations:
Field tests demonstrate 98.7% reliability over 5-year operational periods, outperforming traditional diaphragm seals by 34% in maintenance intervals.
Brand | Response Time | Max Pressure | Accuracy | Certifications |
---|---|---|---|---|
TechInstrum CP-9000 | 1.2s | 6000 psi | ±0.25% | ATEX, SIL-2 |
PrecisionDynamics PDX-7 | 1.8s | 4500 psi | ±0.35% | ASME B40.1 |
FlowMetrics FCAP-12 | 0.9s | 10,000 psi | ±0.18% | ISO 9001:2015 |
Leading capillary type differential pressure gauge companies offer modular designs with:
Custom solutions reduce installation costs by 22% compared to standard models through optimized tube routing and connection layouts.
Oil Refinery Application: A Middle Eastern facility deployed 78 capillary-type units for catalyst monitoring, achieving 99.4% uptime despite 480°C process temperatures. Maintenance costs decreased by $17,000 annually per unit.
Pharmaceutical Plant Case: Hygienic-design gauges with 3-A certified seals improved batch consistency by 15% in sterile filling operations, complying with FDA 21 CFR Part 11 requirements.
Model | Pressure Range | Basic Unit | Smart Version |
---|---|---|---|
Entry-Level | 0-500 psi | $1,200 | $1,850 |
Mid-Range | 0-3000 psi | $2,400 | $3,200 |
High-Pressure | 0-10,000 psi | $4,500 | $6,000 |
Capillary-type systems deliver 23% faster ROI than conventional alternatives through reduced calibration frequency (biannual vs quarterly) and inherent media separation. When selecting differential pressure gauge with capillary
solutions, prioritize suppliers offering NIST-traceable calibration and minimum 5-year performance warranties.
