Its durability and stability suit industrial control systems for oil, gas, and water monitoring. Best for: installations needing a longer connection to the control room without compromising signal quality. Caution: longer cable runs may introduce electrical noise; use proper shielding.
MEASUREMAN 300 PSI Transmitter
This MEASUREMAN model delivers up to 300 PSI with ±0.5% FSO accuracy in a 4-20mA format. It utilizes a stainless steel housing and 316L diaphragm for resistance to corrosive liquids, making it suitable for demanding liquid, gas, and oil environments. Best for: higher-pressure industrial loops where precise monitoring is critical. Caution: ensure proper process isolation to prevent overpressure from damaging the diaphragm.
Buying Guide: Key Considerations For 4-20mA Pressure Sensors
When selecting a 4-20mA pressure sensor, consider range, media compatibility, and mounting style. Ensure the transmitter’s pressure range covers your maximum operating pressure with some headroom to prevent constant over-range signaling. Media compatibility matters; stainless steel bodies and ceramic diaphragms often tolerate aggressive liquids. Check electrical requirements, including supply voltage, loop-powered operation, and signal integrity over long cable runs. G1/4″ threads are common, but verify your fittings. For harsh environments, opt for rugged housings and corrosion resistance. If space is limited, prioritize compact designs with easy installation and wiring access. For multi-point monitoring, a sensor with stable compensation and low drift is valuable to maintain consistent readings over time.
FAQ
- What does 4-20mA output mean? It is a current loop standard where 4 mA represents the zero pressure and 20 mA represents the full-scale pressure, enabling long-distance signal transmission with reduced noise.
- Which material is best for aggressive fluids? Stainless steel bodies with ceramic diaphragms generally offer better resistance to corrosion and wear in harsh liquids.
- Can I mix sensors from different brands? It is possible, but ensure compatible electrical output, range, and fitting size to avoid wiring or mounting issues.
- How do I choose the proper pressure range? Compare your maximum operating pressure, occasional surges, and system margin; select a range that covers peak pressure with a safety buffer.
- Is long cable run a problem for 4-20mA? Not typically, but you may need shielded wiring and proper grounding to minimize signal loss and noise.
- What maintenance is needed? Periodic checks for calibration drift, diaphragm integrity, and connection tightness help maintain accuracy.
