Product Overview
The SP007 is WIKA-ST’s customer-configurable pressure transducer — one all-stainless strain-gauge platform whose range, output, pressure port, and electrical termination are each selected to order. The pressure reference is part of that selection: order it as a gauge (SPG), absolute (SPA), or vacuum (SPV) build on the same body. It spans 0–0.5 to 0–5,000 psi at 0.25% FSO standard (0.1% FSO high-accuracy), with 4–20 mA, 0–5 V, or 0–10 V output, so a single family covers a wide range of general industrial pressure measurements. Have a legacy tecsis part number for this measurement? Send it — WIKA acquired tecsis and now ships these under WIKA Sensor Technology, and we cross-reference the tecsis p/n to the current WIKA-ST equivalent at the same spec.
Key Features & Benefits
- One transducer, built to your spec — a single all-stainless family covers a wide spread of applications without a separate model for every combination, because the four things that vary are set per order rather than picked off a shelf. You get exactly the transducer the install needs, not the nearest catalog stock number.
- Standard or high-accuracy from the same platform — the same body is available at a tighter accuracy and temperature error band when the application needs it, so you can step up precision without changing the form factor or the install. Order the accuracy the job needs, not the one the catalog happens to stock.
- All-stainless and short-lead — stainless wetted parts suit most industrial media, and the configurable platform ships on a short lead from stocked components. A broad-coverage workhorse you do not wait months for.
Specifications
- Sensing principle
- Strain-gauge pressure sensing on an all-stainless element — four ordering axes (full-scale range, signal output, process port, and electrical termination) are set per order, so one transducer family covers a wide spread of builds.
- Pressure type
- Single-ended — the reference is selected by model code: SPG gauge, SPA absolute, or SPV vacuum gauge, on the same SP007 platform. For a wet/wet differential build see the SP007 SPD differential page.
- Measuring range
- 0–0.5 to 0–5,000 psi — selected per model: gauge (SPG) spans the full 0.5 to 5,000 psi spread, absolute (SPA) from 5 psi up, and vacuum (SPV) on the low ranges. The exact full-scale is configured to the application. Other pressure units (bar, kPa, inHg, inH₂O, Torr) are available on the order code.
- Accuracy
- 0.25% FSO standard; 0.1% FSO on the high-accuracy option.
- Thermal effects
- Temperature error band ±1.0% FSO standard; ±0.5% FSO on the high-accuracy option.
- Output signal
- Configured to order: 4–20 mA, 0–5 V, or 0–10 V amplified output. Optional order-code adders: shunt calibration, zero-and-span pots, and an extended temperature-compensated range — each specified at order.
- Excitation / supply
- 9–28 VDC for 0–5 V or 4–20 mA output; 15–28 VDC for 0–10 V output.
- Electrical connection
- Selected to order — 5′ polyurethane cable, 6-pin connector (PTIH-10-6P or equivalent), ½″ NPT conduit fitting with 5′ cable, DIN 43650 (type A), or mini-DIN connector.
- Wetted parts material
- Stainless steel wetted parts.
- Process connection
- Selected to order across NPT, UNF (MS), G (ISO 1179), M12, and SAE J1926 ports in male or female — e.g. ¼–18 NPT, 7/16–20 UNF, G¼, M12×1.5, 9/16–18 SAE.
- Overpressure / proof
- Safe overpressure 3× full scale (10,000 psi max).
- Operating temperature
- −40 to +240°F.
- Compensated temperature
- +40 to +140°F.
- Configuration & lead time
- Customer-configured from stocked components — one of the short-lead WIKA-ST pressure lines; the range, output, port, and termination are set per order. Quote-only, no public price list.
Common Applications
- General industrial process pressure where the full-scale, output, and port have to match an existing install rather than a fixed catalog part
- OEM and machine-builder pressure measurement requiring a specific output and termination
- Hydraulic and pneumatic system pressure monitoring
- Absolute or vacuum measurement on the same body — the SPA absolute and SPV vacuum builds
- Low-range pressure measurement where a configurable full-scale improves resolution
Design & Selection Considerations
- FSO accuracy is a percentage of the range, not the reading — a ±0.25% FSO transducer rated for the full scale can be off by that fraction of full scale anywhere in its range — a larger relative error down at the low end. Size so the working pressure lands in the upper part of the range, and when you compare two sensors make sure both quote accuracy the same way. An oversized range quietly throws away resolution at the pressure you actually run.
- Respect the overpressure limit — the danger zone is below burst — proof / safe-overpressure is the pressure the sensor can see without losing calibration; burst is where it is destroyed. A unit driven past proof but short of burst keeps reporting plausible, wrong numbers. Size for the real worst case — including transients — and recalibrate after any suspected overpressure event. A spike that shifts calibration leaves no visible mark; the reading just drifts.
- Match the wetted material to the medium — the wetted parts see the process chemistry directly; the standard stainless suits most service, but corrosive, high-purity, or sour media want the right alloy specified up front. Use the input form to tell us the medium and we pick the wetted material to it. The wrong wetted alloy fails slowly and silently, not all at once.
To configure the right WIKA-ST SP007 transducer:
To size and select the right transducer, send us: the pressure range and whether it is gauge, absolute, sealed, or differential; for a differential measurement, the maximum line (static) pressure as well as the differential range; the accuracy class you need (standard industrial vs. high-accuracy); the output the receiving device expects (4–20 mA, 0–5 V, 0–10 V, or raw mV/V) and the cable run; the process medium and temperature (so the wetted material and any extended temperature compensation are right); the process connection and electrical termination; and any area classification or agency approval (Ex / intrinsic safety, CSA, FM) and NACE / sour-service material requirement. For a fast transient, give us the rise time or frequency of the event so the natural frequency is sized above it.
