UPT200 Ultraminiature Pressure Transducer

Drop‑in Alternative for Kulite XCQ‑062

The UPT200 is an ultraminiature probe‑based piezoresistive pressure transducer built for space‑constrained test instrumentation. At only 0.6 gram typical weight and 1.7 mm probe diameter, this sensor is designed to be embedded inside custom‑built probes, pressure rakes and test fixtures, where larger standard transducers cannot physically fit or would disturb local flow‑field characteristics.

Built with all‑stainless‑steel construction and full Wheatstone‑bridge sensing element, UPT200 delivers both static and high‑frequency dynamic pressure measurement. It comes with external temperature‑compensation module and PTFE flat ribbon cable assembly. Many R&D labs select UPT200 as a practical drop‑in replacement option for Kulite XCQ‑062 series for aerodynamic and component‑level test campaigns, especially when facing long overseas lead‑times.

Key Benefits for Real‑World Test Set‑ups

• Ultra‑light 0.6 g probe‑type design, minimal flow‑field interference for model‑mounted test hardware
• Wide selection of pressure ranges, supports absolute, gauge, differential and sealed‑gauge pressure types
• Very high natural frequency up to 1000 kHz for capturing fast transient pressure pulsations and shock events
• mV‑level Wheatstone‑bridge output, compatible with standard signal conditioners used for XCQ‑062‑style transducers
• Rugged mechanical structure, rated for 20 g vibration and shock for lab test‑cell environments
• Flexible mechanical customisation: custom cable length, reference pressure tube for differential set‑ups, special range calibration
• External compensation module keeps sensing probe tiny, while stabilising readings across changing temperature

Note: UPT200 is a test‑and‑measurement grade transducer, intended for lab R&D, wind‑tunnel and bench‑test usage, not designed for continuous multi‑year industrial production‑plant duty.

Typical Application Scenarios

Aerospace & Aerodynamic Research

• Wind‑tunnel model embedded measurement, surface pressure mapping on test articles
• Pressure rake probe integration for multi‑point aerodynamic data acquisition
• Fluid‑mechanics lab test rigs, shock‑wave and impulse‑pressure testing
• Component‑level engine bench test for transient pressure pulsation monitoring

Semiconductor Equipment R&D & Test‑Bench

• Chamber pulse‑pressure test inside semiconductor process tool prototypes
• Micro‑flow channel pressure fluctuation study for gas‑supply sub‑system validation
• Test fixture embedded pressure sensing for equipment‑qualification experiments

Remark: UPT200 is for R&D bench‑testing only, not for direct inline UHP production‑gas monitoring. For production‑line clean‑gas measurement please refer to our PK40X series.

• Compact fixture‑embedded pressure measurement on engine test‑benches
• Intake / exhaust transient pressure capture within tight installation envelopes

Industrial Research Laboratory

• Hydraulic‑impact test stands, burst‑test and impulse‑pressure characterisation
• Energy‑power component dynamic‑pressure validation
• Multi‑sensor array measurement where weight and dimension are hard constraints

Technical Specifications

Frequently Asked Questions

Q1: Can UPT200 directly replace Kulite XCQ‑062? What conditions should I note?

A: UPT200 can serve as functional alternative for most wind‑tunnel and bench‑test projects. Matching pressure range, bridge resistance and excitation voltage are required. Please share your original XCQ‑062 part number at quotation stage, we configure range and output parameters to match your existing signal conditioner and DAQ setup. Minor mechanical fixture adjustment may occasionally be necessary; we cannot guarantee zero‑modification for every legacy installation.

Q2: What is the actual usable frequency response on my test rig?

A: The datasheet lists un‑screened natural frequency up to 1000 kHz depending on pressure range. Real‑world dynamic performance will be affected by probe mounting installation, cavity geometry and measured media. For ultra‑fast transient‑pressure tests, mounting method is critical to final measurement quality.

Q3: Can UPT200 measure differential pressure?

A: Yes. We can supply thin 0.4×0.25 mm stainless‑steel reference‑pressure tube routed together with the flat ribbon cable for differential‑pressure set‑ups. Please specify differential‑pressure requirement during quotation.

Q4: What media can this ultraminiature probe‑sensor work with?

A: Wetted construction is all‑stainless‑steel. Suitable for clean non‑corrosive gas and non‑conductive hydraulic oil. Do not expose to strong acid, alkali or salt‑rich seawater. Send your medium composition for material‑compatibility check for special‑fluid projects.

Q5: Why separate compensation module instead of fully‑integrated probe?

A: External compensation module keeps the sensing‑probe diameter and weight extremely small, which is essential for embedding inside thin wind‑tunnel models and pressure‑rake assemblies. Trade‑off is that you need to arrange space for the compensation‑module on your test hardware.

Q6: Can I use UPT200 for 24/7 continuous production‑equipment monitoring?

A: No. UPT200 is test‑bench / R&D grade transducer for short‑term and cyclic lab testing. It is not built for multi‑year non‑stop production‑site operation.

Q7: Can I customise cable length? Are customised orders cancellable?

A: Custom cable length and special mechanical adaptations are supported. Once custom production starts, orders become non‑cancellable. Please provide mechanical drawing and test‑condition requirements for quotation.
