RS PM400-E Analog Output Pressure Transmitter
RS PM400-E combines MEMS piezoresistive sensing with digital compensation and calibration for continuous industrial pressure measurement. Choose a voltage or 4–20 mA output. The 22 A/F body offers standard ranges of 100, 160, 250 and 400 bar.
Applications and selection
For analog signal acquisition in industrial equipment, fluid-pressure monitoring and process control. Match the range and pressure reference first, then check the output, power supply, medium compatibility, thread seal and electrical connector. For pulsating or transient pressure, check the buffer configuration and the overload limit for that range.
Product features

Specifications

TEB is the total error band and includes nonlinearity, hysteresis, repeatability and thermal effects. Confirm other temperature bands for this model’s calibration configuration.
Output and supply matching
| Output signal | Output type | Supply requirement |
|---|---|---|
| 0.5–4.5 V | Ratiometric voltage | 5.0 VDC ±5% |
| 0.5–2.5 V | Absolute voltage | 3.2–5 VDC |
| 0–5 V / 1–5 V | Absolute voltage | 9–30 VDC |
| 0–10 V / 1–10 V | Absolute voltage | 21–30 VDC |
| 4–20 mA | Current | 9–32 VDC; 24 VDC recommended |
Static overload and burst pressure
| Nominal full scale | Static overload pressure | Burst pressure |
|---|---|---|
| 100 bar | 500 bar | 600 bar |
| 160 bar | 500 bar | 800 bar |
| 250 bar | 750 bar | 800 bar |
| 400 bar | 800 bar | 1200 bar |
Check the limit for the selected full-scale range. Neither overload pressure nor burst pressure is a normal operating-pressure rating.
Connections, wiring and installation
Pressure-connection options include G1/4 A face seal, G1/4 A O-ring seal, 1/4-18 NPT, 7/16-20 UNF and M12×1.5. Electrical options include M12×1, Metri-Pack and DIN EN 175301-803-A. Pin assignments vary by output and connector: check this model’s dimensions, wiring and ordering code before installation.
Selection and enquiry
Send the medium, pressure range, operating temperature, output and supply, pressure connection, electrical connector and quantity so we can check the configuration. The matching datasheet provides dimensions, wiring and ordering codes.
