This series is suitable for measurement of liquid or gas pressure, even for difficult media such as contaminated water, steam, and mildly corrosive fluids or gases. The transducer pressure cavity is machined from a solid piece of 17-4 PH 1 stainless steel. The standard version includes a / NPT pipe thread allowing 4 a leak-proof, all metal sealed system. There are no o-rings, welds or organics exposed to the pressure media. The durability is excellent. Measurement Specialties proprietary Microfused technology, derived from demanding aerospace applications, employs micromachined silicon piezoresistive strain gages, fused with high temperature glass to a stainless steel diaphragm. This approach achieves media compatibility simply and elegantly providing an exceptionally stable sensor without the p-n junctions of conventional micromachined sensors. This product is geared to the OEM customer using medium to high volumes. The standard version is suitable for many applications, but the dedicated design team at our Transducer Engineering Center stands ready to provide a semi-custom design where the volume and application warrants.SPECIFICATIONS Performance at 77F (25C): Pressure range 0 to 100, 250, 500, 1000, 2500, 5000, 10000 PSI (consult factory for compound ranges) (0 to 7, 17, 35, 70, 175, 350, 700 BAR) Accuracy (combined linearity, hysteresis and repeatability) .5% of FS Span (for higher accuracy consult factory) Media compatibility 17-4 PH stainless steel (for other material consult factory) Pressure ports 1/4 NPT (for other ports consult factory) 8 Pressure cycles >10 full pressure cycles Pressure overload 2X rated pressure Burst pressure 5X or 20000PSI whichever is less Long term stability (1 year) 0.25% FS Span (typical) Electrical: Supply voltage 5VDC 10-30VDC Supply current <10mA <15mA Outputs 1-5VDC, fixed (4) 0.5 - 4.5VDC, ratiometric to supply (3) 4-20mA two wire (5) Interface 2 ft PVC jacketed cable (for other options consult factory) Zero offset 2% of FS Span (for tighter tolerances consult factory) Span tolerance 2% of FS Span (for tighter tolerances consult factory) Output load 5K Ohm (min) for high level voltage 0 Ohms 10V (1100 Ohms 32V) for 4-20mA Noise < 2mVRMS Bandwidth (-3dB) DC to 1KHz (Typical) ENVIRONMENTAL ORDERING Operating temperature range -40 to 185F (-40 to 85C), (For other MSP400 temperature ranges consult factory) Pressure Range Compensated temperature range 30 to 158F (0 to 70C) P = PSI 1= 2 ft.
