Telemecanique XMLP400BC22 Pressure Transmitter (400 bar, 4–20 mA): Engineering-Focused Guide
The Telemecanique XMLP400BC22 is an industrial pressure transmitter intended for high-pressure measurement and PLC integration via a robust 4–20 mA current loop. The XMLP family is frequently used in demanding environments because the analogue loop is noise-resistant and well supported across industrial control systems.
Search intent typically includes Telemecanique XMLP400BC22 pressure transmitter, XMLP400BC22 400 bar 4-20mA DIN, and Telemecanique XMLP400BC22 G1/4A. For consistent internal naming, keep it strict: Telemecanique XMLP400BC22 pressure transmitter (Brand + code + product type).
What a 400 bar Transmitter Is Really Used For
400 bar is not a casual range. It is typical in hydraulic power units, presses, high-pressure test benches, and specialty machinery where pressure spikes and transient behavior matter. In these systems, pressure measurement is not only about display—it drives alarms, interlocks, quality checks, and predictive maintenance.
A transmitter (not a switch) is chosen when you need continuous data for trending: rising pressure ripple, increasing peak pressure, or unusual oscillations can indicate wear in pumps, valves, or accumulators before a fault becomes downtime.
Key Technical Characteristics (From Datasheet)
The XMLP400BC22 datasheet describes it as a pressure transmitter with 400 bar range, 4..20 mA output, and G1/4A male connection, with a DIN electrical interface. Environmental notes include IP65 protection and vibration/shock resistance details.

Integration Notes: Making a High-Pressure Signal Useful
- Signal scaling: define the exact engineering units mapping and document it (e.g., 4 mA = 0 bar, 20 mA = 400 bar). This prevents dangerous misreads.
- Sampling strategy: if your PLC sampling is slow, you may miss spikes. For hydraulic systems, decide whether you need peak capture or averaging.
- Filtering discipline: too much filtering hides real events; too little creates nuisance alarms. Tune with real process data.
- Mechanical mounting: high-pressure lines can vibrate. Use proper fittings, avoid excessive leverage with long adapters, and follow plant torque practices.
Application Fit
- Hydraulic presses and power units: line pressure trend monitoring
- High-pressure test rigs: continuous logging and tolerance checks
- Specialty machines: pressure-driven sequence validation

FAQ: Telemecanique XMLP400BC22
Is XMLP400BC22 a transmitter or a switch?
The datasheet identifies it as a pressure transmitter with a 4..20 mA output.
What are the connection types?
It is specified with G1/4A male process connection and DIN electrical interface.
Why is 4–20 mA still common in high-pressure systems?
Because current loops are robust against electrical noise and support long cable runs, which is typical around hydraulic equipment and large machines.
