ICS Pressure Sensors – Rugged Industrial Transmitters for Precise Measurement
ICS pressure sensors deliver reliable readings for gauge, absolute and differential pressure—from vacuum to high pressure. Depending on the application, they use ceramic, piezoresistive, thin-film or capacitive sensing elements. Outputs include 4–20 mA and 0–10 V, with options for IO-Link/Modbus to enable fast parameterization and diagnostics. Housings and wetted parts in stainless steel 316L and seals such as FKM, EPDM, PTFE ensure high media resistance.
ICS Schneider Messtechnik supports you with sizing, media & material checks, process connections, damping/protection (snubbers, cooling elements, diaphragm seals) and calibration (ISO/DAkkS). If required, we integrate your measuring points into PLC/DCS or IIoT (edge, MQTT/HTTPS) for transparent, traceable processes.
FAQ on ICS Pressure Sensors
At a glance: selection, accuracy, media compatibility, connections, EMC, calibration and integration.
Which outputs do ICS pressure sensors offer?
Standard outputs are 4–20 mA (2-wire) and 0–10 V (3-wire). Selected models feature IO-Link or Modbus RTU (RS-485) for extended diagnostics and quick integration.
What measuring ranges are available?
From vacuum up to the high-pressure range (model dependent). As a rule of thumb: working pressure × 1.3–2.0. With pulsation/spikes, choose a larger range or add damping.
What accuracy can I expect?
Typically ±0.25…1.0% FS (model dependent). For QA/test, variants with a tighter Total Error Band (TEB) are available.
Which process connections are offered?
| 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 industry |
| Hygienic (Tri-Clamp) | EHEDG | Food/Pharma (with diaphragm seal) |
Which media are ICS sensors suitable for?
For air, water, oils as well as many corrosive media. Wetted materials are typically 316L; options include Hastelloy®/Monel®. Select seals to match the medium (FKM/EPDM/PTFE/FFKM).
How do I protect the sensor from pressure spikes?
Use snubbers/orifices, capillaries or a diaphragm seal. Additionally enable measurement filtering in the PLC/controller.
What is the correct wiring?
- 4–20 mA (2-wire): wire +/− in series through the analog input.
- 0–10 V (3-wire): +Ub, GND, Signal—avoid ground loops.
Which EMC measures are recommended?
Use shielded, twisted-pair cable, ground the shield on one side, ensure equipotential bonding, and route power/signal cables separately.
What ambient/media temperatures are permitted?
Model dependent (see datasheet). For hot media, use a cooling element/siphon or remote mount; consider temperature effects (TEB).
Are variants available for hazardous areas?
Yes—selected ICS sensors are available with ATEX/IECEx approvals (e.g., Ex ia). Please inquire for your project.
How often should I calibrate?
Recommendation: annually; for QA/safety loops semi-annually/quarterly or after overload/service. ISO/DAkkS certificates available.
How do I integrate ICS sensors into IIoT?
Connect analog to a PLC/edge or digitally via IO-Link/Modbus. An edge gateway publishes values securely via MQTT/HTTPS to SCADA/cloud.
What typical error sources should I avoid?
- Range too small → overload/saturation
- No damping with pulsation → noise/wear
- Wrong seal/materials → leaks/chemical attack
- EMC/ground loops → offset/drift
Do you support selection, documentation and commissioning?
Yes—from media review and sizing/drawings to calibration and commissioning, including test reports and BOMs.
