VTS VTS0234-47-AP025 – Compact Pressure Transmitter for 0–25 bar Absolute Monitoring

The VTS VTS0234-47-AP025 is a compact industrial pressure transmitter designed for stable, repeatable 0–25 bar absolute measurements. From my experience, models carrying the “-47” suffix in this family are set up for 2‑wire 4–20 mA loop output, which makes integration into existing PLC/SCADA systems straightforward. You might notice that the “AP025” range code typically points to an absolute pressure span up to 25 bar—well-suited for closed hydraulic loops, compressed air lines, and clean process media where drift and noise have to be kept in check.

Key Features

• 0–25 bar absolute range – AP025 appears to denote an absolute span for applications where barometric changes shouldn’t affect readings.
• 4–20 mA, 2‑wire output (-47) – Easy to run over long distances with good noise immunity; most PLCs accept it out of the box.
• Stable, low-drift sensing – In many cases you’ll see better long-term stability than low-cost transmitters, which saves recalibration time.
• Rugged, compact form factor – Typically a stainless-steel wetted path and a sealed electronics head for demanding plant environments.
• Fast response – Suitable for control loops where you can’t afford slow updates or lag.
• Common process connections – Usually available with standard threads like G1/4 or 1/4″ NPT for quick swap-in; verify the exact variant when ordering.

Technical Specifications

Application Fields

This transmitter fits well into:

• Hydraulics and pneumatics – closed-loop pressure control and condition monitoring.
• Compressed air systems – compressor discharge and receiver tank absolute pressure.
• Process and OEM machinery – skid builders typically use this range for clean media lines.
• Water treatment & utilities – pump header pressure and filtration skid monitoring.
• HVAC/Building automation – chiller/boiler loop pressure where absolute reference helps stability.

A maintenance lead at a packaging plant told me they swapped in this series to replace mixed legacy sensors; wiring stayed 2‑wire, the 4–20 mA scaling was spot on, and calibration drift over six months was negligible.

Advantages & Value

• Reliability – Stable output with fewer nuisance trips, which typically cuts unscheduled downtime.
• Compatibility – 4–20 mA is universal; most plants can adopt it without new I/O cards.
• Cost-of-ownership – Reduced recalibration frequency and simple spares strategy for multi-line plants.
• Support-ready – Clear range coding (AP025) and output type (-47) simplify replacement and documentation.

Installation & Maintenance

• Mounting environment – Install in a ventilated cabinet or shielded area if ambient temperatures are high; avoid vibration hot-spots on the line.
• Wiring – Use twisted-pair shielded cable for long 4–20 mA runs; earth the shield at a single point to minimize loops.
• Process connections – Apply compatible sealant; for absolute sensors, avoid blockage of the port; use a snubber if you see pressure spikes.
• Safety – Depressurize the line before removal; verify media compatibility with sensor wetted materials.
• Routine care – Check zero/span annually; clean ports if media can crystallize; verify firmware or labeling updates during audits.

Quality & Certifications

• CE conformity for EMC and safety is typically available for this series.
• RoHS compliance for hazardous substances, in most cases.
• UL/cUL marking may be offered on specific variants; confirm at order time.
• Manufacturer’s warranty: 12 months (365 days).

One thing I appreciate is how predictable the range/output coding is—it makes replacement planning much easier. If you can share the exact process connection and electrical connector you prefer, we’ll align the sub‑variant, confirm lead time, and lock the price.
