Huba Control Type 528 — Relative & Absolute Pressure Transmitter

The Type 528 is a compact pressure transmitter built on Huba Control's ceramic sensor technology, refined over more than 20 years. It covers relative pressures from -1 to 60 bar and absolute pressures up to 16 bar, with a rugged stainless steel construction, negligible temperature drift, and one of the widest connector and pressure-fitting selections in its class — making it a strong fit wherever a process engineer needs one reliable transmitter across multiple mounting configurations.

Why the Ceramic Sensor Matters

Most low-cost pressure transmitters use a thin-film strain gauge bonded to a metal diaphragm, which can drift with temperature and is vulnerable to fatigue over repeated pressure cycles. The Type 528 instead uses a ceramic (96% Al₂O₃) measuring cell — ceramic is dimensionally stable across a wide temperature range, chemically inert to most process media, and highly resistant to overpressure and cyclic fatigue. The practical result for a plant engineer: negligible temperature influence on accuracy (±0.2% FS per 10K), and a transmitter that holds its calibration over years of service rather than months.

IJ Instruments is a reliable source for Huba Control pressure transmitters in Tamil Nadu and pan India, helping engineers match the right pressure range, output signal, connector and pressure-fitting combination to their application — with free technical consultation before you finalize your specification.

FAQs

Type 528 — Frequently Asked Questions

What's the difference between relative and absolute pressure on this transmitter?

Relative (gauge) pressure is measured against ambient atmospheric pressure, while absolute pressure is measured against a fixed vacuum reference — the Type 528 is available in both relative (up to 60 bar) and absolute (up to 16 bar) versions.

Can the Type 528 be used in a hazardous area?

Yes — ATEX and IECEx intrinsically-safe versions are available for both the 4–20mA and ratiometric output types, suitable for Zone-rated hazardous locations.

Which connector should I choose?

It depends on your panel and cabling standard — Swift connector and M12x1 are common for new installations, while DIN EN 175301-803-A/C suits many existing industrial panels. Share your preference with us for confirmation.
