Titanium pressure sensor resists corrosive materials

A compensated, media-isolated, mV output pressure sensor has been introduced by Measurement Specialties, signalling an expansion of the existing 154 Series. The 154B (Backside) sensor is designed without a header for o-ring mounting for OEM applications where compatibility with corrosive media is required. 

The 19mm small profile sensor is constructed of either 316L stainless steel or ASTM Grade 2 CP titanium. The titanium option offers greater resistance to corrosive materials and harsh cleaning chemicals, opening the range of its application use to things such as dialysis machines and salt/brackish water measurements.

The 154B’s “headerless” design is a lower cost solution for low pressure applications where the silicon pressure die is attached “upside down” directly to the stainless steel or titanium module. From 0 - 300psi in gage and 0 - 28bar in absolute, the 154B compensated has a pressure non-linearity of ±0.3 %Span with an overload pressure of 2x rated and burst pressure of 3x rated. Operating at a -40°C to +105°C temperature range, this pressure sensor accomplishes the feat of having a compensated temperature range of -20 to +85°C — a range currently unrivaled in the marketplace.

This backside compensated pressure sensor excels at various applications such as: medical instrumentation (dialysis machines), process control, fresh/waste/salt/brackish water measurements, refrigeration/compressors, pressure transmitters and hydraulic controls. Please contact our team of experienced engineers for more custom configurations of this pressure sensor to meet your specific application needs.
