Siemens Pressure Sensors – Analog Transmitters for Process & Machinery
Siemens pressure sensors (e.g., SITRANS series) provide reliable, continuous measurements via 4–20 mA or 0–10 V, covering gauge, absolute and, depending on model, differential pressure. Robust measuring cells (ceramic, piezoresistive, thin-film) and wetted parts in stainless steel 316L ensure long service life—from HVAC/OEM to the process industries.
ICS Schneider Messtechnik supports selection, sizing, material/seal choice and the right process connection. On request, we provide ISO/DAkkS calibration and integrate measuring points into PLC/SCADA or—via edge gateways—into IIoT architectures (MQTT/HTTPS).
FAQ on Siemens Pressure Sensors (Analog)
Compact guidance on signals, accuracy, installation, media, EMC and documentation.
Which output signals do Siemens transmitters offer?
Standard outputs are 4–20 mA (2-wire) and 0–10 V (3-wire). 4–20 mA is ideal for long cable runs and high noise immunity; 0–10 V is easy to evaluate and common in OEM/HVAC.
How do I choose the correct measuring range?
Rule of thumb: working pressure × 1.3–2.0. For pulsation/spikes, select a higher range or use a pressure snubber.
What accuracies are typical?
Depending on model, typically ±0.25…1.0% FS. For quality-critical tasks, choose variants with a tight Total Error Band (TEB).
Which process connections are available?
| Connection | Standard | Use |
|---|---|---|
| G 1/4, G 1/2 | ISO 228 (BSPP) | Industrial standard |
| ¼″ / ½″ NPT | ASME | Tapered, self-sealing |
| M20×1.5 | ISO metric | Process & machinery |
| Hygienic (Tri-Clamp/Varivent®) | EHEDG | Food/Pharma (often with diaphragm seal) |
What about media compatibility?
Wetted parts typically 316L; for aggressive media consider Hastelloy®/Monel® and suitable seals (FKM, EPDM, PTFE/FFKM). Verify compatibility for your medium and temperature.
How do I protect the sensor from pressure spikes?
Use a snubber/orifice, capillary, or diaphragm seal. Also enable measurement damping/filtering in your controller.
What supply voltage is required?
Typically 12–30 V DC. Observe permissible ripple and provide sufficient current headroom for 4–20 mA loops.
What is the correct wiring?
- 4–20 mA (2-wire): connect +/− in series through the analog input.
- 0–10 V (3-wire): wire +Ub, GND, Signal separately; avoid ground loops.
Which EMC practices are recommended?
Use shielded, twisted-pair cable; ground the shield at one end; ensure equipotential bonding; route power and signal cables separately.
What temperature limits apply?
Model-dependent (datasheet). For hot media, use a cooling element/siphon or remote mount; consider temperature influence on TEB.
Are variants available for hazardous or hygienic areas?
Yes—selected models with ATEX/IECEx approvals and hygienic design are available. Specify your requirements for selection.
Can Siemens sensors be integrated into IIoT?
Yes—analog outputs can feed an edge gateway for secure publishing to SCADA/cloud via MQTT/HTTPS. Some Siemens series also offer digital interfaces (e.g., IO-Link/HART), depending on the device.
How often should I calibrate?
Recommendation: annually; in QA/safety loops semi-annually/quarterly or after overload/service. ISO/DAkkS certificates available.
Do you support selection & commissioning?
Yes—from media/material checks, sizing and calibration to commissioning, including documentation, test reports and BOMs.
