Measurement Specialties Expands 154 Series of Media Isolated, Piezoresistive Silicon Pressure Sensors

Measurement Specialties, an expert in sensor design and manufacturing, has now expanded its 154 Series of media isolated, piezoresistive silicon pressure sensors with the small profile, backside compensated 154B.

Versatile Media Isolated Pressure Sensor from Measurement Specialties Withstands Extremely Corrosive Environments (PRNewsFoto/Measurement Specialties Inc.)

Housed in a 316L stainless steel package as standard, the compact 19 mm sensor is also available in an ASTM Grade 2 CP titanium housing for exceptionally harsh environments. This broadens the 154B's uses from process controls, refrigeration and compressors, hydraulic controls and fresh water measurement to medical equipment, such as dialysis machines, as well as more corrosive environments, including brackish and salt water.

The headerless design of the 154B enables a low-cost solution for low pressure applications where the silicon die is attached "upside down" directly to the module. The O-ring mountable sensor is easily and securely incorporated into OEM applications that contain corrosive materials or harsh cleaning chemicals.

Standard ranges for pressure are from 0 psi to 15 psi up to 0 psi to 300 psi in gage reference format as well as from 0 bar to 7 bar up to 0 bar to 28 bar in absolute reference. The sensor features a pressure non-linearity of +/-0.3% span with an overload pressure of 2X rated (up to 500 psi) and a burst pressure of 3X rated (up to 600 psi).

The unit's wide compensated temperature range spans from -20 degrees C to +85 degrees C, and has a typical zero pressure output of 100 mV.

Silicon oil provides a stable, reliable transfer of pressure from the sensing package diaphragm to the sensing element itself.

A ceramic substrate with laser-trimmed resistors is attached to the package to provide temperature compensation as well as offset correction. An additional resistor is used to adjust an external differential amplifier and provide span interchangeability to within +/-1% for exceptional measurement accuracy.
