DatasheetDynisco 830, 850 & 860 Series General Purpose Pressure Sensors
The Dynisco 830, 850 and 860 Series pressure sensors are flexible general purpose transducers for reliable pressure measurement in a wide range of industrial applications. The sensors offer a measurement accuracy of ±0.5 % FSO including linearity, hysteresis and repeatability.
The interchangeable configuration allows users to specify the pressure range, pressure port and output level to meet the requirements of the application. Available pressure ranges extend from 0…100 psi to 0…30,000 psi. Depending on the model, output signals of 3 mV/V, 5 VDC or 10 VDC are available.
The sensors use a bonded strain gauge design and provide excellent temperature compensation. The compensated temperature range is 0…150 °F or -18…66 °C. Wetted materials are made of 17-4 PH and 15-5 PH stainless steel, while the cover material is 303 or 304 stainless steel.
