Pressure Sensors for Industrial & Hazardous Applications
Review transmitter and digital-gauge paths for process control, local indication, hydraulic equipment, and OEM integration. Confirm current performance, environmental limits, and document scope for the selected configuration.

Start with pressure type, normal and surge range, wetted materials, process connection, signal or display, power, enclosure, and area classification. Published model data is a selection aid; the controlled datasheet, certificate scope, test documents, warranty, and commercial terms must be confirmed for each RFQ.

Decide by Installation & Area Classification
Match the measurement principle to fluid, pipe access, and hazardous-area requirements before you compare commercial terms.
ATEX and ex-certified pressure selection
If an RFQ requires hazardous-area equipment, send the area classification and required protection concept. Request the current certificate and verify its holder, model scope, marking, issuer, and validity before selecting either pressure instrument.
OEM and private-label pressure gauges
For private-label or ODM work, send artwork, packaging, range, display, documentation, first-order quantity, and annual volume. Branding feasibility, tooling, fees, MOQ, validation, and schedule are confirmed after review.
Which Pressure Instrument Should I Buy?
Use the two model paths to identify the datasheet, environmental, documentation, and OEM questions that require confirmation.
| Buyer need | Start here | Alternative | Guidance |
|---|---|---|---|
| Process signal to PLC, DCS, or SCADA in a hazardous area | AM-PT300 pressure transmitter | AM-PG200 digital pressure gauge | Start with the transmitter path, then verify output, protection concept, certificate holder, exact model scope, marking, and validity for the site classification. |
| Local digital readout, battery power, or private-label gauge | AM-PG200 smart digital pressure gauge | AM-PT300 if a remote signal is also required | Start with the local-display path, then confirm the current display, power, range, branding feasibility, MOQ, and schedule in the datasheet and quotation. |
| High-vibration hydraulic or heavy machinery duty | AM-PT300 pressure transmitter | AM-PG200 for local panel indication | Send the measured vibration profile and mounting details; do not treat a general industrial-use description as a verified vibration rating. |
| Battery-powered field gauge without wiring | AM-PG200 digital pressure gauge | AM-PT300 pressure transmitter | Confirm the current battery and transmitter power requirements in the quoted model datasheets before system design. |

Pressure Sensors Selection Guide
Use these checks before sending an RFQ. They help our engineers confirm the right model, output, material, and certification for your project.
Set the pressure range
Choose a range with enough overload margin for pump starts, hydraulic spikes, and process surges; avoid running the transmitter at its limit.
Confirm process connection
Specify G1/4, G1/2, NPT, M20, flange, diaphragm seal, or sanitary connection, plus wetted material compatibility with the medium.
Check environment and certification
For hazardous or outdoor sites, state the area classification, ingress, vibration, cable-entry, and calibration-document requirements, then verify them against current controlled records.
Pressure Sensors FAQ
How should I verify hazardous-area suitability for a pressure instrument?
Send the area classification and required protection concept. Request the current certificate and confirm its holder, exact model scope, marking, issuer, and validity before ordering; do not infer coverage from a category-page label.
What is the OEM MOQ for pressure instruments?
MOQ depends on the selected model, artwork, packaging, tooling, testing, documentation, and customization scope. It is stated in the project quotation after these inputs are reviewed.
Which AccuMeasure pressure instrument is better for hydraulic systems?
AM-PT300 is the high-vibration industrial transmitter option. Send your pressure range, process connection, output signal, and vibration profile so our engineers can confirm the configuration.
