NOSHOK PTI Series IO-Link pressure transmitters: control and safety notes for mines
Reviewed by Joe Ashwell

First reported on Australian Mining
30 Second Briefing
NOSHOK’s PTI Series intelligent pressure transmitters introduce IO-Link communication to mining pressure monitoring, pairing digital point-to-point connectivity with high-accuracy, rugged transmitters suited to harsh plant environments. The IO-Link interface enables parameterisation, continuous diagnostics and remote reconfiguration from PLCs or distributed control systems, reducing manual intervention on slurry lines, dewatering circuits and hydraulic systems. For brownfield sites, the devices can drop into existing 2‑wire or 3‑wire pressure transmitter locations while adding structured digital data for predictive maintenance and tighter process control.
Technical Brief
- IO-Link integration enables cyclic process data plus acyclic diagnostic data over the same physical connection.
- Parameter sets can be cloned and downloaded to multiple PTI transmitters directly from the PLC engineering tool.
- Continuous device diagnostics support detection of sensor drift, overpressure events and internal faults before hard failure.
- Remote re-ranging and damping adjustment reduce the need to open panels in hazardous or noisy plant areas.
- Structured error codes and status bits allow alarm segregation between instrument failure and genuine process excursions.
- Digital communication reduces analogue signal integrity issues such as ground loops and EMI on long cable runs.
Our Take
Within the 810 Product/Safety-tagged mining pieces in our database, relatively few focus on pressure instrumentation, which suggests NOSHOK’s PTI launch is targeting a more specialised slice of plant and mobile-equipment safety compared with the more common PPE or collision-avoidance products.
For Australian operations, IO-Link–enabled transmitters such as NOSHOK’s are likely to integrate more cleanly with existing PLC and SCADA upgrades that many sites are rolling out under broader digitalisation programs flagged across recent Mining category coverage.
Vendors like NOSHOK that can demonstrate improved diagnostic capability in pressure devices are well placed to align with Australian regulators’ emphasis on proactive plant condition monitoring, which has been a recurring theme in safety-oriented Mining stories in our database.
