Original manufacturer photo. STS PS350 original photo. Exact model and Ex approval depend on order code; photo alone does not prove certification.

Hermetically sealed analog pressure transmitter, manufacturer family up to 600 bar and –40 to +125°C, with accuracy specified at 25°C. No ATEX/IECEx rating is claimed without an order-specific certificate.

Product-level QA: This entry documents the verified manufacturer family, not every current SKU. Orderable electrical and mechanical variants, exact certificate schedule and a manufacturer-source model photograph remain subject to individual review. Never treat a family name as universal hazardous-area approval.

Manufacturer-verified specifications

STS lists the PS350 hermetic analog pressure transmitter for 0–600 bar, media temperature −40 to +125°C (ambient −40 to +100°C per April 2025 datasheet) and ±0.25% FS accuracy at 25°C. No ATEX/IECEx approval has been asserted for this model; use the specific datasheet and selected order code for design decisions.

PS350 — electrical variants and real ambient limits

Selection pointModel-specific evidence
Specified pressure variantsApril 2025 sheet: 0–10, 16, 25, 250, 400 or 600 bar.
Performance±0.25% FS at 25°C (best-fit straight line); response <2 ms.
Current / voltage supply4–20 mA: 8–32 VDC; 0–10 VDC: 12–32 VDC; 0.5–4.5 VDC: 8–32 VDC.
Temperature distinctionMedia −40…125°C; ambient and storage −40…100°C.
Sealing and enclosureHermetic internal port; connector-dependent IP65–IP69. G¼ port can still require an external FKM seal.

The 0.5–4.5 V output does not imply a 5 V supply: this sheet specifies 8–32 VDC. At 24 V, its stated loop-load formula gives a maximum 800 Ω total burden. Include receiver and cable resistance in that budget. Do not treat proof or burst pressure as a continuous measuring range. Source: April 2025 manufacturer datasheet.
